Fisher Globe Control Valves

Fisher Globe Control Valves are available in a variety of sizes (NPS ½ thru 36) and provide users with performance and flexibility.

They can help solve an array of application needs from big to small, hot to cold, general to severe. Fisher globe control valves have a selection of valve cages or plugs that can be interchanged to modify the inherent flow characteristic to linear, equal percentage, or quick opening to meet capacity demands from 0.0001 Cv up to 12,000 Cv. Fisher easy-e™ control valves pioneered the use of cage-guided trim.

Globe Valve

Globe Valves use a linear motion to move a closure member into and out of a seating surface. They have a body distinguished by a globular-shaped cavity around the port region. Many single-seated valve bodies use a cage or retainer-style constructions to retain the seat ring, provide valve plug guiding, and provide a means for establishing particular valve flow characteristics. Cage or retainer-style single-seated valve bodies can also be easily modified by the change of trim parts to provide reduced capacity flow, noise attenuation, or reduction or elimination of cavitation

HART® field Temperature Transmitter WIKA

HART® field Temperature Transmitter WIKA

The TIF series field temperature transmitters, consisting of a rugged field case, model T32 temperature transmitter and a model DIH display, have been designed for general use in process engineering.

They offer high accuracy, galvanic isolation and excellent protection against electromagnetic influences (EMI). Via the HART® protocol, the TIFxx is configurable (interoperable) with a variety of open configuration tools.

In addition to the different sensor types, e.g. sensors in accordance with DIN EN 60751, JIS C1606, DIN 43760, IEC 60584 or DIN 43710, customer-specific sensor characteristics can also be defined, through the input of value pairs (user-defined linearisation).

Through the configuration of a sensor with redundancy (dual sensor), on a sensor failure, it will automatically change over to the working sensor. Furthermore, there is the possibility to activate sensor drift detection. With this, an error signalling occurs when the magnitude of the temperature difference between sensor 1 and sensor 2 exceeds a user-selectable value.

The field temperature transmitter also has additional sophisticated supervisory functionality such as monitoring of the sensor lead resistance and sensor-break detection in accordance with NAMUR NE89 as well as monitoring of the measuring range.

Moreover, these transmitters have comprehensive cyclic self-monitoring functionality. Via the display, it is possible to show range alarms as well as MIN and MAX values.

The field temperature transmitter is available in various field case variants. Plastic, stainless steel and aluminium can be specified. It can be mounted directly on a wall. A pipe mounting kit is also available for fitting to pipes with a diameter of 1 … 2″. The field temperature transmitters are delivered with a basic configuration or configured according to customer specifications.

Valve Positioner Samson

Valve Positioner Samson

Valve Positioner Samson Type 3730

A valve Positioner is a device used to increase or decrease the air load pressure driving the actuator until the valve’s stem reaches a “POSITION” balanced to the output SIGNAL from the process variable instrument controller.

Valve positioners are used on controlling valves where accurate and rapid control is required without error or hysteresis.

Positioners are generally mounted on the side-yoke or top casing of the pneumatic actuator for linear sliding stem control valves, and at/near the end-of-shaft for rotary control vales. For either basic design type, “mechanical feedback linkage” connected directly to the valve’s stem provides feedback to the controller. The process controller tells the positioner to “change” position; the feedback linkage reports back to the positioner confirming that a change has occurred and gives a “sense” of the magnitude of the change in position.

Emerson Micro Motion

For over 30 years, Emerson’s Micro Motion has been a technology leader delivering the most precise flow, density and concentration measurement devices for fiscal applications, process control, and process monitoring.

Emerson’s Micro Motion Coriolis, density and viscosity technologies deliver superior flow measurement expertise while providing customers with the confidence and insight they need to continuously improve safety and efficiency in the most critical process applications.

The Micro Motion flow meter’s measuring tube comes in a variety of shapes, and vendors have sales pitches for each of them. So you’ll have to decide for yourself which suits your purposes best. The most common is the omega or “U” sensor.

Whatever the shape, the tube has a drive coil to vibrate the tube at a specific frequency. And at the inlet and outlet ends of the tube, you find pickoffs measuring this frequency.

If there’s no flow, then both pickoffs vibrate at the same frequency, creating identical waveforms. When you have a flow, it creates the Coriolis effect, a small twist that phase-shifts the waveforms from the pickoffs. Thus by measuring the amount of shift, you can calculate the mass flow rate.

And as for density, you’ll use the natural change of frequency that occurs in a change of fluid density. High density makes the frequency decrease, and low makes it increase. So you can use these changes to find the density of the product with great accuracy.
