Pressure Transducer 4-20mA/Voltage

The signal system of 4-20mA and 1-5V output by the pressure transmitter is stipulated by international standards.In the signal circuit, the pressure transmitter is equivalent to a variable resistor. It is connected in series with the power supply, ammeter (indicator), and load resistance (including wire resistance). The function of the pressure transmitter is to change the current in the circuit in the range of 4-20mA by changing its own resistance according to requirements.The pressure acts on the sensor, and the sensitive element deforms. The deformation will cause the resistance or capacitance value to change. And then it will be converted into an analog 4-20mA output by the conversion circuit.

FAQ

What is pressure transmitter how it works?

Pressure Transmitters are sensors with electrical transmission output for remote indication of pressure. Process transmitters differentiate themselves from pressure sensors through their increased range of functionality. They feature integrated displays, offer high measuring accuracies and freely scalable measuring ranges. Communication is via digital signals, and waterproof and explosion-proof certifications are available. Through connection to diaphragm seals, they are suitable for the harshest operating conditions. Ideal for OEMs, process applications, water processing, and industrial pressure applications.

What is the input of pressure transmitter?

A pressure transmitter is an instrument that converts pressure variables into a standardized output signal that can be transmitted. And there is a given continuous function relationship between the output signal and the pressure variable (usually a linear function). Mainly used for measurement and control of industrial engineering pressure parameters. Differential pressure transmitters are often used for flow measurement.
There are two types of pressure transmitters, electric and pneumatic. The electric standardized output signals are mainly 0mA ~ 10mA and 4mA ~ 20mA (or 1V ~ 5V) DC signals.

How do you calibrate a pressure transmitter?

If the transmitter is used for a period of time, it may cause a change in metering performance. There will be zero drift and increased measurement error. Therefore, it is necessary to perform regular calibration. The accuracy of the calibrator used for calibration should be more than 3 times the required calibration accuracy. Use the pressure calibrator to input the standard pressure values of 0%, 25%, 50%, 75%, and 100% of the range to the transmitter in the forward and reverse directions. Check whether the current output signal is within the allowable accuracy range. If it is out of tolerance, it needs to be adjusted. The adjustment method is as follows (4 ~ 20mA output):
(1) Input a standard pressure of 4mA with a pressure calibrator. Adjust the ZERO (zero) potentiometer. Make the 4mA current output within the accuracy range.
(2) Input a standard pressure of 20mA with a pressure calibrator. Adjust the SPAN (range) potentiometer. Make the 20mA current output within the accuracy range.
(3) ZERO and SPAN will contain each other. Repeat steps (1) (2) until the current output of 4mA point and 20mA point meets the accuracy requirements at the same time. Then check whether the current output of the 25%, 50%, 75% range point meets the accuracy requirements. The transmitter is qualified if it meets the requirements.

What are the types of pressure transmitter?

There are different types of pressure transducers based on their design.
These sensors can come in several shapes and sizes,
but the technology inside can also differ. 
There 4 main types of pressure sensor based on this: 
Strain Gauge Pressure Transducers
Capacitance Pressure Transducers
Potentiometric Pressure Transducers
Resonant Wire Pressure Transducers
