HVAC Stainless Steel Sheath Sensor

Stainless Steel Sheath Sensor

The Sensor Scientific Stainless Steel Sheath Sensor enables accurate temperature measurement on the surface of ducts, pipes and tanks from remote locations. This sensor can be utilized in mechanical equipment rooms. The sensor is usually strapped to a pipe or a duct and secured with cable ties, clips or brackets. The operating temperature range is from - 10°C to + 110°C (+10°F to +230°F). RTD (Resistance Temperature Detector) with resistance values 100, 500, 1,000 & 2,000 Ohms at 0°C is also available as a temperature measuring element.
