Product Description
The PM07X series differential pressure transmitter encapsulates the differential pressure chip in the positive and negative pressure chambers of the product. Pressure is introduced through the threaded interfaces at both ends to act on the chip, outputting a linear voltage. Combined with a dedicated digital circuit, after signal processing such as signal amplification, linear compensation, anti-interference, and surge protection, it becomes an integrated product that outputs industrial standard signals.
Product Application
◆Petrochemical industry;
◆Constant pressure water supply;
◆Measurement and control technology;
◆Hydraulic and pneumatic fields;
