PTJ601 Fire Wind Pressure Difference Controller (Economic Type), PTJ601X (Type 86) Residual Pressure Detector, Wind Pressure Control System

The PTJ601 same type wind pressure differential controller is used to control front rooms, shared front rooms, fire elevator front rooms, and enclosed refuge floors The normally open contact of the pressure difference controller is closed, and the power supply of the rooftop bypass pressure relief valve control box is connected. The bypass pressure relief valve located on the rooftop is opened for air supply and pressure relief, and the bypass pressure relief valve located on the rooftop is opened for air supply and pressure relief, reducing the pressure difference. When the pressure difference drops to a certain value, the contact of the pressure difference sensor is disconnected, the rooftop bypass valve is powered off, and the bypass valve closes to stop pressure relief. Exclusive instruments

The product features include:

1: Using airbag inflation to pull high-speed elastic material,

2: After reaching the set pressure, the high-speed action switch point is triggered

3: The gas source method makes the PTJ601 sensor have strong overload resistance

4: There are fine inspection indicator lights and alarm lights on the surface When working, the green inspection indicator light will turn on, and when the wind pressure is sensed to be too high, the red light will turn on and there will be passive switch action

Mainly used in fire positive pressure air supply, pressure sensing and differential control of pressure relief valves, and action of residual pressure valves Used in industrial systems for the purpose of controlling small pressure differentials This product is also known as a positive pressure air supply sensor, pressure difference measurement and control device, air pressure difference sensor, etc!
