TRH***2 fire air pressure difference controller (expanded economy type)Pressure sensor for building fire supply, pressure sensor for fire protection industry, fire pressure difference controllerThe wind pressure difference controller is used to control the front room, the front room, the fire elevator front room, and the closed refuge floor. The differential pressure controller normally opens the contact closure, and connects the power supply of the control box of the roof bypass pressure relief valve. 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 for air supply pressure relief, reducing the pressure difference, when the pressure difference
The value is reduced to a certain value, the wind pressure difference sensor contact is disconnected, the roof bypass valve is de-energized, and the bypass valve is closed to stop the pressure relief. Exclusive instrument.
Product features are:
1: Using the airbag to expand and pull the high-speed elastic body,
2: After reaching the set pressure, the high-speed action switch point is activated.
3: The way of air source makes the PTJ**1 sensor have strong anti-overload capability.
4: There are fine inspection indicators and warning lights on the surface. When working, the inspection indicator green light is on. When the wind pressure is exceeded, the red light is on and there is passive switching action. The main application is in the positive pressure supply of fire. Sense differential pressure control pressure relief valve, residual pressure valve action. There is a small differential pressure control for the purpose of industrial systems. This product is also known as positive pressure air supply sensor, differential pressure measurement controller, wind pressure difference sensor, etc.!
