Siemens 536-811 : Duct Temperature Sensor, 100K Ohm Thermistor, Point Sensor, 4 inches (rigid), bracket mount Probe, -40°F to 180°F (-40°C to 82°C)
The Siemens 536-811 duct temperature sensor monitors and transmits changes in duct air temperature to your HVAC control system for accurate, reliable temperature measurement. This point sensor uses a 100K Ohm Thermistor element with a 4 inches (rigid), bracket mount probe. Measuring range is -40°F to 180°F (-40°C to 82°C). Accuracy is ±0.50°F (±0.28°C) @ 77°F (25°C). Bracket-mounted units do not include housing.
