The PreCon Model ST-O* Outdoor Air Thermistor Sensor provides precision remote temperature sensing for building automation systems and mechanical equipment room instrumentation. The active sensing element is a highly stable precision thermistor material accurate to within ±0.36°F (0.2°C).
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 weather shield is mounted on a weatherproof outlet box for easy installation on an outdoor surface. This rugged enclosure will assure a long life, even under extreme weather conditions.
