HVAC Duct Sensor With Mounting Bracket

Duct Sensor with Mounting Bracket

thermistor sensor
The Sensor Scientific Duct Sensor with Mounting Bracket enables accurate temperature measurement in multiple applications such as mechanical rooms, ducts, pipes and immersion installations. The assembly consists of 304 stainless steel tube housing and mounting. Operating temperature range is from - 10°C to +110°C (+10°F to +230°F) The sensor is also available in an RTD (Resistance Temperature Detector) form with resistance values 100, 500, 1,000 & 2,000 Ohms at 0°C.
