This pressure transmitter uses a high-precision, high-stability pressure sensor component from an internationally renowned company. Through a highly reliable amplification circuit and precise temperature compensation, the pressure of the measured medium is converted into4～20mADC,0～5VDC,0～10VDCand1～5VDCand other standard electrical signals. High-quality sensors, advanced encapsulation technology, and comprehensive assembly processes ensure the excellent quality and optimal performance of this product. The product is available with multiple interface configurations and lead options, meeting customer requirements to the greatest extent and being suitable for use with various measurement and control equipment.

Operating Principle

When a pressure signal acts on the sensor, the pressure sensor converts it into an electrical signal. After amplification by a differential amplifier and an output amplifier, the signal is finally converted through theV/A voltage-to-current converter into a4-20mA standard current output signal that has a linear relationship with the liquid-level pressure of the measured medium (liquid).
