This pressure transmitter uses a high-precision, high-stability pressure sensor element from an internationally renowned company. Through a highly reliable amplification circuit and precise temperature compensation, it converts the pressure of the measured medium into4～20mADC,0～5VDC,0～10VDCand1～5VDCand other standard electrical signals. High-quality sensors, exquisite sealing technology, and complete assembly processes ensure the excellent quality and optimum performance of this product. This product offers a variety of interface forms and wiring methods, enabling it to meet customer needs to the greatest extent and making it suitable for supporting use with various measurement and control equipment.

Working Principle

When the pressure signal acts on the sensor, the pressure sensor converts the pressure signal into an electrical signal, which is amplified through differential amplification and output amplification, and finally converted byV/Avoltage-current conversion into a4-20mAstandard current output signal with a linear corresponding relationship to the liquid level pressure of the measured medium (liquid).
