The pressure transmitter uses a high-precision, high-stability pressure sensor component. After high-reliability amplifier circuit and precise temperature compensation, the pressure of the measured medium is converted into 4~20mADC, 0~5VDC, 0~10VDC and 1~. Standard electrical signals such as 5VDC, high-quality sensors, superb packaging technology and a complete assembly process ensure the superior quality and performance of the product. The product has a variety of interface forms and a variety of lead methods, to meet the needs of customers to the maximum extent, suitable for a variety of 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 by differential amplification and output amplifier, and finally converted into a linear relationship with the liquid pressure of the measured medium (liquid) by the V/A voltage current. 4-20mA standard current output signal.
