Learn about Pressure Transducers
What is a pressure transducer? A pressure transducer or pressure transmitter converts an applied pressure into an electrical analog output signal that is both linear and proportional to the applied pressure to the transducer. Pressure sensors, pressure transducers, and pressure transmitters are commonly referred to as just pressure transducers. The output electrical signal from a pressure transducer is sent to computers, PLC's, chart recorders, digital panel meters or other devices that interpret this signal and use it to display, record, and/or change the pressure in the system being monitored. Most transducers use a strain gauge as the primary sensing element. Pressure transducers with strain gage sensors feature small size, fast response and high reliability.
Electrical Output of Pressure Transducers
Most industrial pressure transducers are available with either a 4-20mA or a 0-10 volt electrical output signal.
4-20mA Output Pressure Transducers
Current output transducers are also referred to as pressure transmitters. The 4-20mA 2-wire loop powered signal is widely used in the industrial and process industries. Advantages of current output pressure transducers include; high immunity from electrical noise, low installation cost – only two wires needed, wiring distances up to thousands of feet may be possible, and built-in diagnostic capabilities.
Voltage Output Pressure Transducers
Pressure transducers with 3-wire voltage outputs are available with 0-10 volt, 0-5 volt and 1-5 volt signals. Transducers with voltage output signals are used with many types of meters, programmable controllers and chart recorders.
Types of Pressure Transducers
Industrial Grade Pressure Transducers
Industrial pressure transducers are precision engineered to fit the majority of industrial pressure measurement applications. These transducers feature enhanced accuracy of 0.25% of span, zero and span adjustment for recalibration and circuit boards with surface mount technology potted in silicone gel for protection against vibration, shock, and humidity.
