Duct & Outside Air Humidity/Temperature Sensors
NSB-10K-2-H200

Duct Humidity Sensor

NSB-10K-2-H200-D-BB2

Outside Humidity Sensor

NSB-10K-2-H200-O-BB2

The Duct/OA Humidity/Temperature Sensor is a 2% accurate relative humidity sensor that includes a thermistor temperature sensor. The sensor can be ordered for duct or outside air applications. The transmitter can be wired for either a 0 to 5 VDC output or a loop powered 4 to 20 mA output.

Outside Air Temperature Sensor

NSB-10K-2-O-BB2

The Outside Air Temperature Sensoris a thermistor sensor for outside air mounting. The probe is made to protect the sensor from rain, sleet, snow or bird droppings. The enclosure is NEMA 4 and UV rated.
