Product Description

Yuanben Pressure Transducer PST series
1. Description
The PST-003 high-pressure pressure sensor developed by Shanghai Yuanben, is made of ceramic film piezoresistive chip and integrated circuit technology. The principle is that the resistance printed on the ceramic film changes after being affected by the pressure. The voltage signal output proportional to the pressure change can be obtained through the measuring circuit.

Shanghai Yuanben produces a variety of pressure sensors, widely used in central air, heat pump and variable-frequency multi-split air conditioning systems. The measuring pressure range is 0~4.5MPa. The interface threads are M10, M12, 7 / 16-20unf, G1 / 4, etc. The electrical connection is provided with special plug-ins and cables. The product can be used in industrial environment. The sensor has good medium compatibility, stable and reliable performance and high precision. In fact, the measured life has reached more than 5 million pressure cycles, and the average trouble free working time is more than 50000 hours. At the same time, we have many kinds of pressure sensors for high, medium and low pressure, such as 0-2MPa PST-002.
