The VA 400 series of compressed air and gases sensor works on the calorific principle in a robust housing with and without display.
The sensor is inserted into the flow path and can be done so even under pressure, the VA-400 is mounted with a standard 1/2“ball valve.
A safety ring avoids an uncontrolled ejection of the probe which may be caused by the operating pressure.
The VA-400 is available in the following probe lengths: 120, 160, 220, 300, 400 mm.
The flow sensors can be mounted into existing pipelines with inner diameters of 1/2“upwards.
The correct sensor positioning is established by means of an engraved depth scale on the sensor bar.
The mounting depth corresponds with the respective probe length.
