Scanmatic - Model SM4441 -Humidity Absorption System

SM4441 is used in installations with gauge pressure sensors. It is important that water is not allowed to enter the pressure compensation capillary. This may damage the sensor. SM4441 consist of a desiccant breather, including silica gel to absorb the humidity, mounted on an aluminum bracket. A plastic tube is used to connect to the capillary of the pressure sensor. The dimension for the tubes may vary depending on the type of sensor that shall be used. The wires from the pressure sensor is connected to terminal blocks including overvoltage protection. The overvoltage protection must be connected to ground with the shortest possible cable as possible. SM4441 is typically delivered without encapsulation and is installed inside a cabinet together with the datalogger. The SM4441 can also be delivered in a dedicated box or cabinet of steel, aluminum or composite material.
