TRH-212X fire positive pressure air supply special differential pressure sensor (display control integrated)Fire air supply system pressure sensor, pressure difference control instrument


The air pressure difference sensor is used to control the front room, the front room, the front room of the fire elevator, and the closed refuge floor. The differential pressure controller is normally open and closes, and the power supply of the control box of the pressure relief valve is connected to the roof. The top bypass pressure relief valve is opened for air supply and pressure relief, and the bypass pressure relief valve at the top of the building is opened to provide air pressure relief, reduce the pressure difference, and when the pressure difference is reduced to a certain value, the wind pressure difference sensor The contact is broken, the bypass valve on the roof is de-energized, and the bypass valve is closed to stop the pressure relief. Exclusive instrument.

Product features are:

1: Using sensing technology, the core components are imported from abroad.

2: And use the microprocessor circuit to directly change the sensor signal into a changeable passive switch signal.

3: The output action point is more accurate and repeatable.

4: This product is equipped with new technology to make the reset process change according to user requirements.

5: Reliable quality is equivalent to a new direction of sensing and controller. The price is equal.

6: Improved high-precision display, so that any part of the time can reflect the current pressure changes.

Mainly used in fire positive pressure air supply sensing high differential pressure control pressure relief valve, residual pressure valve action. High precision required differential pressure control for the purpose of industrial systems. This product is also known as positive pressure air supply sensor, pressure Differential measuring controller, wind pressure difference sensor, etc.!
