Installation and Use Guide for A3S Digital Differential Pressure Gauge

The A3S digital differential pressure gauge is one of the important products under the TRD brand of Tianjin Runda Zhongke Instrument,The A3S digital differential pressure gauge/transmitter is suitable for micro differential pressure applications that require pressure monitoring and alarm. It is a complete intelligent system, including LED display, button settings, sound alarm, and relay output.This digital differential pressure gauge/The transmitter is divided into a high-pressure chamber and a low-pressure chamber by a rubber diaphragm inside. When the pressure in the high-pressure chamber is higher than that in the low-pressure chamber, the rubber diaphragm will move towards the low-pressure chamber, driving the mechanism to produce a small displacement. The electronic circuit measures the pressure difference through radio frequency non-contact displacement measurement technology.
