Pressure Transducers Keep Environmental Conditions Exact

Sales contact



Calibration labs typically require specific knowledge of local environmental conditions. Environmental chambers allow the pressure, temperature, humidity, and light levels inside calibration labs to be controlled precisely.

How can they achieve such exact barometric conditions? The answer is simple: pressure transducers.

How Environmental Chambers are Used

Environmental chambers come in a variety of sizes, from reach-in, like the one pictured on the right side, to walk-in, and are used for in applications such as mechanical testing and archiving and storage.

A hydraulic dynamometer uses pressure transducers to measure the pressure of hydraulic fluids and can be networked with computer systems to determine correlated torque or other desired values.

Typical environmental chamber atmospheres include standard air, inert gases, and hazardous or combustible substances at a wide range of pressures. Because of this, pressure transducers used to measure pressure in environmental chambers must be compatible with all those types of media. Hazardous environments rated Class I, Division 1 or 2 require the use of explosion-proof, non-incendive, or intrinsically safe components.

The Role of Pressure Transducers

Pressure transducers monitor the pressure inside the environmental chamber and interface with a control system to actuate the compressors and pressure-relief valves inside the chamber.

The following WIKA electronic pressure transducers have been designed for performance, quality, and precision in environmental chambers in test and measurement calibration lab applications:
