Underwater sensor supply

The underwater sensor supply uses high-precision and high stability resistance strain gauges as the pressure sensing chip of the transmitter. The selected surface mount technology is matched with high-precision and high stability amplification integrated circuits with zero point, full-scale compensation, and temperature compensation. The pressure of the measured medium is converted into standard electrical signals such as 4-20mA, 0-5VDC, 0-10VDC, 0.5-4.5VDC, etc. The product structure adopts a fully sealed welding structure, which greatly improves the impact resistance, overload capacity, and sealing performance of the product. The maximum pressure of the product can reach 150MPa. There are multiple ways to connect the product process and electrical connections, which can maximize the satisfaction of user needs.
