| This Sensor Scientific Duct Sensor with Handy Box enables accurate temperature measuring in multiple applications such as mechanical rooms, ducts, pipes and immersion installations. The assembly consists of 304 stainless steel tube housing and handy box. Operating temperature range is from - 10°C to +110°C (+10°F to +230°F) Duct Sensor is also available in RTD (Resistance Temperature Detector) form with resistance values 100, 500, 1,000 & 2,000 Ohms at 0°C.
Standard Configuration: Sensor in stainless steel tube and wall mountable handy box.
Optional Configuration: Sensor in stainless steel tube, handy box and mounting bracket.
Wiring:
All electrical connections and wiring must comply with the National Electrical Code and with local electrical codes.
Ordering Information
Thermistor: Select the appropriate type of thermistor to suit your instrumentation.
Housing: Select the appropriate length of stainless steel tube.
For example: 10K Ohm, 0.2°C accuracy /8" long tube -Model No. HVDB-WM103C/8
REFER TO THE HVAC EQUIPMENT AND SYSTEMS COMPATIBILITY CHART.
