GrowControl PresSense negative pressure sensor

The negative pressure sensor measures the current negative pressure value at the end of the connected pressure measuring hose. The digital climate controller receives the negative pressure values ​​and regulates the speed of the supply air fan to maintain the negative pressure at the desired value.

The vacuum sensor is connected to the controller using a 5m cable with an RJ45 connector. The included hose is connected to the blue hose labeled "Inside" on the sensor, which is then routed into the box or room where the vacuum is to be controlled.

If the sensor is located in the room where the negative pressure is to be controlled, the long hose is connected to the black hose on the sensor labeled "Outside" and led to the outside.

Scope of delivery:

• Pressure sensor with 5m cable
• 4m hose for pressure measurement
• Wall mounting (Velcro)
