ST-O* Series

Precon Outside Air Thermistor and RTD Sensor

The PreCon Model ST-O Outside Air Sensor provides precise remote temperature sensing for building automation systems and mechanical equipment room instrumentation. The active sensing element is a highly stable precision thermistor material or platinum RTD. The temperature sensitive element is sheathed in a stainless steel tube and mounted inside a ventilated, treated, white PVC shield to minimize radiant energy and weather related effects. The air sensors have a weather shield mounted on a weather resistant outlet box for easy installation on an protected outdoor surface. This rugged enclosure will assure a long life, even under extreme weather conditions.
