Application Scenarios
It is widely used in pressure monitoring and process control for boiler air supply, underground mine ventilation, cleanroom automation, covering power generation and coal mining industries.
Structural Features
The transmitter is assembled with OEM silicon piezoresistive differential pressure sensing cores. The default housing is made of aluminum alloy, and stainless steel housings are available for harsh working conditions. Its dual pressure ports adopt M10 thread + cock structure, which can be mounted directly on pipelines or connected externally via pressure impulse tubing.
