Comparison of Model 232 and 213 WIKA Pressure Gauges

What is a pressure gauge?

The pressure is generally defined as a force that acts uniformly over a specified area. When you press the button on a doorbell, for example, the pressure of your fingertip applies a physical force that triggers an electric actuation switch inside the doorbell, which then sends a signal to chime. In industrial applications, the force that is applied over an area is usually a gas or liquid, but it can also be a solid.

Eugene Bourdon (1808–1884) was a brilliant French watchmaker and engineer who invented the Bourdon gauge in 1849. This revolutionary new pressure measurement device enabled accurate measurement of much higher pressures than existing measurement devices. Bourdon designed the device for steam locomotive engines, but the notably more useful and robust pressure measurement device allowed engineers to develop a range of industrial machinery that operated at higher pressures. Besides its relative simplicity and accuracy, the Bourdon gauge can measure much higher pressures than the U-tube manometer pressure gauges used at the time. With the Bourdon gauge, engineers could now measure pressures in excess of 100,000 psi.

Pressure Calibrator CA700 YOKOGAWA

The new Yokogawa CA700 Portable Pressure Calibrator is equipped with a silicon resonant sensor that uses Yokogawa proprietary DPHARP technology. The CA700 can measure pressures with an accuracy that is within ±0.01% of rdg*, making it one of the most accurate portable pressure calibrators on the market. This highly accurate portable pressure calibrator features a variety of functions that includes a wide selection of measuring ranges, as found/as left data storage, and memory capacity to store calibration procedures. The Yokogawa CA700 provides an accurate and efficient calibration and verification tool for pressure/differential pressure transmitters and other types of field devices for commissioning or regular inspection.

What is Pressure Calibrator

Pressure calibrators come in a wide variety. A pressure calibrator is simply a pressure measuring device capable of verifying (or calibrating) the pressure reading of another pressure measuring device. These devices might also be called pressure standards. The pressure calibrator must be more accurate than the device being calibrated. Traditionally, the calibration ratio is 4:1. This means that the pressure calibrator is 4 times more accurate than the device it is calibrating.

A pressure calibrator can also have secondary features that facilitate the calibration. For example, a pressure calibrator may have the capability to measure the output from the device under test (DUT). It might also have an internal pump capable of generating pressures used in the calibration, or it could have a precision regulator that can control a supply pressure and maintain a precise pressure output. Pressure Calibrator is a widely used term that can mean a lot of different things to a lot of different people.

Applications

1- Field Calibration of Differential Pressure and Pressure Transmitters

Calibration of pressure transmitters is required to accurately measure the input and output values and to calculate the error rate.
The CA700 ensures reliable calibration with its function to accurately measure the input and output values of pressure and current.
Additionally, its embedded calibration procedures enable users to perform certain calibration following the prescribed procedure.

2-Pressure Switch Test

A pressure switch test measures the pressure at the time when the contact opens and closes and the resistance at the time when the dead band contact closes.
A test procedure is embedded to enable users to carry out a test following the prescribed procedure.

3-Check and I/O Adjustment of an Electro-pneumatic Converter

Input and output adjustment of an electro-pneumatic converter is carried out by applying rising and falling currents of 0, 25, 50, 75, and 100% of the span.
A reliable test can be carried out with the CA700 that has a 4-20 mA step function for signal generation and a capability to accurately measure the generated pressure.

4-20 mA SIMULATE (Two-wire Transmitter Simulator)

The CA700 can also be used as a transmitter simulator to carry out a loop test. It can absorb (SINK) the set current from an external voltage generating device (e.g., a distributor system or PLC) of instrumentation equipment.
4-20mA current can be sourced with an accuracy of 0.015% of the reading.

5-Two-wire Transmitter Loop Check

DC mA signals can be measured by supplying power to the transmitter from a 24 V DC power supply.
DC mA signal measurement and zero-point check can be performed with an accuracy of 0.015% of the reading.
A 250-ohm resistor for HART and BRAIN communication is included in this calibrator so there is no need to attach an external resistor when connecting to a handy terminal.

6-Input Command Check and Adjustment of Recorders and Controllers

Instrumentation loop test and operation/command check can be performed by sourcing DC 1-5 V / 4-20 mA instrumentation signals with an accuracy of 0.015% of the reading. Furthermore, two patterns of linear sweep and step sweep can be selected (the sweep time can be specified from 15, 30, 45, and 60 sec).

It is also possible to do filter monitoring with the differential pressure transmitter.

Beside the devices with silicon or diaphragm seal for differential pressure, level, dp flow measurement, Deltabar electronic dp is a differential pressure system combining two sensor modules and one transmitter. In level applications, the high-pressure sensor (HP) measures the hydrostatic pressure. The low-pressure sensor (LP) measures the head pressure. The level or differential pressure is calculated in the transmitter using these two digital values.

Differential pressure measurement:

Measuring Principle

Silicon cell:

The operating pressure deflects the process isolating diaphragm and a fill fluid transfers the pressure to a resistance bridge (semiconductor technology). The pressure-dependent change in the bridge output voltage is measured and evaluated.

Diaphragm seal:

The operating pressure acts on the process isolating diaphragm of the diaphragm seal and is transferred to the process isolating diaphragm of the sensor by a fill fluid.

Pressure gauges Snubbers Model 910.12

Pressure gauge snubbers are intended to suppress the effect of pressure pulses and pressure peaks, which are common reasons for gauge failure. Porous snubbers incorporate a fixed mesh disk. Piston snubbers are supplied with five pistons for use with a variety of media. Adjustable pressure gauge snubbers are provided with an adjustable needle valve that enables the operator to restrict the flow as operating conditions may demand even when the snubber is in service.

Pressure gauge snubbers will considerably increase the service life of pressure gauges in harsh applications such as on reciprocating pumps and compressors, hydraulic presses or fluid power systems and will additionally improve the reading accuracy of the gauge.

pressure snubbers protect your pressure gauge or transducer from pressure spikes and surges and damaging pulsation. Snubbers extend the life of your pressure instruments because they protect the bourdon tube and movement from seeing harsh spikes and surges that could cause failure by rupturing the diaphragm of the transducer or the gauge bourdon tube or causing the movement teeth to skip or dislodge.

Snubbers reduce the day to day “wear and tear” on the instrument, lessening the need to replace. Units are available in both brass and 316 stainless steel, and in three different porosities for various pressure media including gas, liquid, and heavy oil.

Overpressure Protectors are triggered to protect your pressure instrument when the pressure exceeds the rated set pressure.  A spring-loaded piston triggers a valve to close when the pressure goes over the pressure range, protecting the instrument from a pressure surge or spike.  Once the pressure falls back to normal the spring will open the valve again.  All units are made of 316 SST for corrosive pressure media.  Three different part numbers are available, depending on your pressure requirements.

Snubbers Application

Snubbers are typically used in-line with a pressure gauge to suppress line pulsations and keep the gauge pointer steady.

Pressure gauge snubbers will substantially increase the life of a pressure gauge where there is pulsation in the line. i.e. for use on pumps, hydraulic presses or fluid power systems. They will also improve the reading accuracy of the gauge.

Bourdon Tube Gauge WIKA Model 213.53

The Bourdon-tube gauge, invented about 1850, is still one of the most widely used instruments for measuring the pressure of liquids and gases of all kinds, including steam, water, and air up to pressures of 7,000 Bar.

The device (also shown in the figure) consists of a flattened circular tube coiled into a circular arc. One end is soldered to a central block and is open to the fluid whose pressure is to be measured; the other end is sealed and coupled to the pointer spindle.

When the pressure inside the tube is greater than the outside pressure, the tube tends to straighten, thus turning the pointer. The pressure is read on a circular scale.

Applications

  • For measuring points with high dynamic pressure loads or vibrations
  • For gaseous and liquid media that are not highly viscous or crystallizing and will not attack copper alloy parts
  • Hydraulics
  • Compressors, shipbuilding

Bourdon tube pressure gauge with switch contacts model PGS23 WIKA

Wherever the process pressure has to be indicated locally, and, at the same time, circuits are to be made or broken, the model PGS23.1×0 switchGAUGE can be used.

Switch contacts (electrical alarm contacts) make or break an electric control circuit dependent upon the position of the instrument pointer. The switch contacts are adjustable over the full extent of the scale range (see DIN 16085), and are mounted predominantly below the dial, though also partly on top of the dial. The instrument pointer (actual value pointer) moves freely across the entire scale range, independent of the setting.

The set pointer can be adjusted using a removable adjustment key in the window.

Switch contacts consisting of several contacts can also be set to a single set point. Contact actuation is made when the actual value pointer travels beyond or below the desired set point.

The pressure gauge is manufactured in accordance with DIN 16085 and fulfils all requirements of the relevant standards (EN 837-1) and regulations for the on-site display of the working pressure of pressure vessels.

As switch contacts magnetic snap-action contacts, reed switches, inductive contacts – for requirements to ATEX – or electronic contacts for triggering a PLC are available.

Applications
