When properly mounted, this sensor can detect temperatures in the range of -40 to 185 degrees fahrenheit. The thermistor is contained within a 8 inch stainless steel housing.We offer other temperatures probe configurations that can be used in a variety of applications. The WBP-TR-02-xx is a 5 inch version of this probe, the WBP-TR-03-xx is designed to be mounted in HVAC ducts, and finally the WBP-TR-04-xx is a lug mounted probe that can be used on equipment such as motors.PowerPower for the sensor is provided by the Whisker.Block®.MountingThe sensor is housed in a 8 inch long tube with a top mounted flange. The flange has two .3 inch holes for mounting to the duct.It should be mounted so that the sensor is fully inserted into the duct and is oriented so that the air will flow over the sensor as it passes through the duct.Take care not to crimp or otherwise damage the sensor as that might adversely affect proper operation or might shorten the operating life of the sensor.Compatible Whisker.Blocks®Part NumberWB1-9-xx-TRNNNNNN-0000-xxWB1-9-xx-TRTRNNNN-0000-xxWB1-9-xx-DCTRNNNN-0000-xxWB1-9-xx-DCTRTRNN-0000-xxWB1-9-xx-DCTRTRNN-7000-xxWB1-9-xx-C1TRTRNN-0000-xxWB1-9-xx-C2TRTRNN-0000-xxWB1-9-xx-C3TRTRNN-0000-xxWB1-9-xx-C4TRTRNN-0000-xxWiringD6 Labs Probe-Long DiagramRecommended Wiring:ConnectorPinSensor WireDescription11RedSensor power supply12 or 3Blue/BlackThermistor output
