Description
Description
The FST1000 Series measures airvelocity and provides two SPSTalarm contact closures correspondingto high and low alarm set points. Thealarm set points are adjustable from 0to 100% of the air flow range. Theunit comes with a green power LED,and two red LEDs for high and lowalarm indications. They can be usedin research and development labs,HVAC applications, exhaust/ventilation hoods and othermanufacturing processes. The sensordesign is based on RTD elements;the air velocity is measured by theheat loss from the RTD sensor as itcools down by the air flow. Thesensor probe comes in twoconfigurations, fixed mount andremote probe.
