① Operating Pressure Range: Pressure measuring range the sensor can be safely operated. ② Operating Mode: Absolute pressure, or gauge pressure ③ Maximum Pressure or Burst Pressure: The maximum value of pressure that can be withstood by the sensor without damaging itself. If the applied pressure is more than this maximum pressure value, it might result in device failure or inaccurate signal output, even damage the sensor itself, which named burst pressure. ④ Output Type: It could be Ratio-metric mV, 4~20mA, 0.5Vdc~4.5Vdc, 0~5Vdc, 0~10Vdc, digital I2C and digital SPI. ⑤ Full Scale: Maximum pressure that the sensor can measure from zero pressure. ⑥ Operating Temperature Range: The temperature range the sensor can operate reliably and provide an accurate output signal.

Output types of pressure sensors include the following four types: ① Ratiometric Millivolt Output(mV): Pressure sensor with ratiometric millivolt output are widely used in many applications because of their cost-effective nature. The full scale output of a millivolt sensor is from 40mV（Min.）to 120mV(Max.); 70mV (Typ.) under power of 5VDC or Idd=1.5mA. The output is directly proportional to the excitation power. ② Current Loop Output(4~20mA): These are pressure sensors with a current output of 4-20 mA. Since this kind of signal outputs are not much affected by electrical noise, the signals can be transmitted over a long distance. ③ Analog Voltage Output(Vdc). These are pressure sensors with a voltage output of 0.5~4.5Vdc, 0~5Vdc, and 0~10Vdc etc, which could be easily read by PCL, controller or indicator. ④ Digital output: The output signal in the case of a digital signal of I2C, SPI with digital code for pressure output values.

The base body is made of stainless steel. The resistance structure is produced by photolithography. Thin-film measuring cells stand out due to their excellent resistance to pressure peaks and bursting pressure.

Industrial pressure sensors also referred to as pressure transducers, pressure transmitters, pressure indicators and pressure switches, normally have a diaphragm type design that uses strain gauges, which are either bonded to or diffused into it, with the strain gauges acting as resistive elements.

Terms of pressure sensor, pressure transducer and pressure transmitter are somewhat interchangeable in the industrial world. Pressure sensors can be described with a 4-20mA output signal and pressure transducers with a millivolt signal.
