Top 5 Considerations For Selecting a Pressure Transducer

Industrial pressure transducers are used in a wide variety of applications ranging from HVAC/R compressors, refrigeration and variable speed pumps to hydraulic pressure, oil and water. A transducer can be used anywhere there's a pipeline or chamber, its function is to sense and convert pressures into a proportional electrical output signal that is transmitted to monitoring or control system.

Setra's Pressure Transducer Handbook

The sensing and measurement of physical quantities through small changes in electrical capacitance is scarcely a new concept. The natural benefits of this approach were recognized for many years. But it was not until Setra engineers introduced new materials, new designs, and innovative, dedicated circuitry that the techniques full potential was realized in the practical, real world of pressure measurement.

How Do Shock & Vibration Affect a Pressure Transducer?

Shock & vibration are two potential mechanical problems for pressure transducers.

Shock is a sudden, unexpected impact that transmits energy to a device in a relatively short time interval. For a pressure transducer, that energy passes through the stainless steel up through the housing. Shock may originate from rough transportation and handling, such as by trucks, forklifts and conveyors. Alternately, shock can be caused simply by dropping the transducer on the shop floor or by an assembler slamming a cabinet door adjacent to it. A transducer may not be damaged by a single shock, but can experience fatigue failure with numerous low-level shocks over the course of its life.

Will Extreme Temperatures Cause Transducer Failures?

Excessively high temperatures are a common source of pressure transducer difficulties.

Like most other electronic equipment, pressure transducers are effected by temperature, shock and vibrations. They consist of numerous components that only function within specified temperature ranges. Transducers exposed to temperatures exceeding those ranges during the assembly process can be adversely affected.

How to Convert mA to Voltage

Converting mA to voltage is common in HVAC when working with pressure transducers. Terminology to keep in mind includes:

  • 1 mA = 0.001 AMP (short for amperes)
  • Amps are referred to as CURRENT
  • Resistor values are in OHMS (Ω is the symbol for ohms)
  • VOLTAGE is the result of passing amps through a resistor
