Water supply pressure transmitter

Overview of Water Supply Pressure Transmitter Products

This pressure transmitter uses high-precision and high stability pressure sensor components. After a highly reliable amplification circuit and precise temperature compensation, the pressure of the measured medium is converted into standard electrical signals such as 4-20mADC, 0-5VDC, 0-10VDC, and 1-5VDC. The high-quality sensor, sophisticated packaging technology, and perfect assembly process ensure the excellent quality and best performance of the product. This product has multiple interface forms and lead methods, which can meet the needs of customers to the maximum extent and is suitable for the matching use of various measurement and control equipment.

Working principle of water supply pressure transmitter

When the pressure signal is applied to 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 4-20mA standard current output signal that corresponds linearly to the liquid level pressure of the measured medium (liquid) through V/A voltage and current conversion.
