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.

Gas Actuated Thermometer WIKA model 73

Dial thermometers use a metal pointer on a circular scale to indicate temperature measurements. They have two main components: the needle and a temperature sensor.  The way a dial thermometer works depends on the type of thermometer it is. Options include bimetal, liquid or gas-filled and vapor-tension, they are described below.

The model 73 gas-actuated thermometer has been developed and is manufactured in accordance with the EN 13190 standard. The high-quality thermometer has been designed especially for the requirements of the process industry. Especially in the chemical and petrochemical, oil and gas, and power engineering industries, the thermometer completely manufactured from stainless steel is used successfully.

The stem, the process connection and the case of the gas-actuated thermometers are made from stainless steel. To allow optimum fitting to the process, individual insertion lengths and process connections are available. The thermometers have a high ingress protection of IP65 and can be used in outdoor applications even at negative temperatures. With liquid damping operation under high vibration, conditions are possible. Due to the wide variety of possible designs, the model 73 gas-actuated thermometers can be perfectly adapted to any process connection or location.

With the adjustable stem and dial version, the case can be adjusted precisely to the desired viewing angle. With the contact bulb version, temperature measurements are possible without any contact with the medium, even when the pipe diameter is extremely small. The contact bulb is intended for external mounting on pipes and tanks. When mounting this thermometer version, it must be ensured that the contact bulb is in contact with the measuring point over its complete length.

Bourdon Tube Gauge WIKA Model 213.53

Bourdon Tube Gauge WIKA Model 213.53

/0 Comments/in /by

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

General Service Solenoid Valves ASCO series 8210

ASCO solenoid valves control the critical flow of air, gas, water, oil, and steam in applications spanning numerous industries. ASCO’s RedHat power management technology sets a new industry standard for reliability and power consumption, accepting both AC and DC voltages while improving performance.

These 2-way, 3-way, and 4-way solenoid valves can handle most fluid control applications and are now available with Class I, Division 2 approvals

ASCO General Service Valves

ASCO general service valves control the flow of neutral gases. They are known for their long life and fast response time available in multiple mounting configurations.

The solenoid is an electromagnetic part of a valve, comprised of a coil, core tube, core, and enclosure. The ASCO RedHat brand offers the world’s largest selection of 2-way, 3-way, and 4-way solenoid valves, designed to handle the most demanding fluid control applications.

ASCO’s 2-Way solenoid valves have one inlet and one outlet and are used to permit and shut off fluid flow. The two types of operations are Normally Closed (NC) and Normally Open (NO). Two types of constructions apply to 2-way solenoid valves, which are direct acting and internally piloted.

With Direct acting constructions, the solenoid is energized, the core directly opens the orifice of a Normally Closed valve or closes the orifice in a Normally Open Valve. The valve will operate at pressures from 0 psi to its rated maximum.

Internally piloted constructions use line pressure to assist operation. When the coil is de-energized (on a Normally Closed Valve), the pilot orifice is closed and line pressure is applied to the top of the piston or diaphragm through the bleed orifice, closing the valve.

ASCO 3-Way Solenoid Valves have three pipe connections and two orifices. When one orifice is open, the other is closed and vice versa.

They are commonly used to alternately apply pressure to exhaust pressure from a valve actuator or a single acting cylinder. These valves can be normally closed, normally open or universal.

ASCO 4-Way Solenoid Valves have four or five pipe connections, commonly called ports. One pressure inlet, two cylinder ports providing pressure to the double acting cylinder or actuator and one or two outlets to exhaust pressure from the cylinders. They have three types of construction, single solenoid, dual solenoid or single air operator.

Remote Mount Industrial Thermocouple Model TC15

Thermocouples generate a voltage directly dependent on temperature. They are particularly suited for high temperatures up to 1,700 °C (3,092 °F).

Instrument designs from mineral-insulated sheathed cable are very resistant against extremely high vibration loads (depending on instrument model, the sensor element and wetted materials). For WIKA thermocouples, the accuracy classes standard and special limits (ASTM E230) or classes 1 and 2 (IEC 60581) are available.

TC15 series thermocouples are remote mounted industrial assemblies supplied with or without a temperature transmitter.

They are designed for applications where direct mounting is inaccessible, where there is excessive radiated or conducted heat, or applications where high vibrations exist.

An extensive range of elements, connection heads, insertion lengths, and process connections can be individually selected for the appropriate application.

Replacement sensors can also be configured for this model. Thermocouples in this series can be inserted directly into a process, or combined with a variety of thermowell designs.

Special Features

  • The sensor can be mounted into a thermowell or directly into a process with the use of a spring-loaded or compression process fitting.
  • The assembly can be supplied with or without a transmitter. Transmitters convert the millivolt input from the thermocouple to a linear analog or digital output (commonly 4-20 mA). This signal reduces potential inaccuracies in the circuit and negates the requirement for thermocouple extension wire.
  • The assembly has electrical approvals for explosion proof hazardous locations, ingress protection, and general purpose areas.
  • The thermocouple sensors available for this assembly are provided with a variety of sheath materials including austenitic 300 series and ferritic 400 series stainless steel, corrosion resistant and high-temperature oxidation resistant alloys.
  • Thermocouple diameters range from 0.063 inches to 0.250 inches and 1.5 mm. to 6 mm. Standard diameters are 0.125 inch & 0.250 inch and 6 mm.
  • For applications that are exposed to outside weather conditions or where moisture is present, the flexible armor extension can be provided with a moisture-proof jacket of PTFE or PVC.
