Flow Switches & Sensors

SWL Air flow monitoring

The SLF... sensor can be used in combination with an ASL… evaluation device to monitor the flow in the air (e.g. in air-conditioning systems). The switching point is adjustable.

Overview

The SLF... sensor can be used in combination with an ASL… evaluation device to monitor the flow in the air (e.g. in air-conditioning systems). The switching point is adjustable. While the fan starts up the switch-on bypass is active. The bypass duration (2 – 60 s) is adjustable.The air flow monitors work according to the calorimetric principle. A thermistor is heated up. As heat is withdrawn by the flowing air, the thermistor resistance alters. The change in resistance is evaluated. As the resistance also depends on the temperature of the medium, the difference must be determined by a second thermistor. The difference is compensated and in this way the switching point is kept stable.Suspended materials adhering to the sensor can have an insulating effect and so affect themeasurement result and hence the defined switching point. Therefore it is advisable to remove any dirt during routine maintenance operations.
