When properly mounted, this sensor can detect temperatures in the range of -40 to 185 degrees fahrenheit. The thermistor is contained within a 5 inch stainless steel housing that can be used in air, food products, and most liquids. It is available with a 6 inch and 3 foot cable.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 .25 inch round by 5 inch long stainless steel tube. It comes with a .25 inch NPT compression fitting that can be used to mount the probe in a tank, duct, or any other surface with a properly sized hole.It should be mounted so that the bottom half the tube is fully submerged in the medium you are monitoring.Take care not to crimp or otherwise damage the stainless steel tube 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-Medium DiagramRecommended Wiring:ConnectorPinSensor WireDescription11RedSensor power supply12 or 3Blue/BlackThermistor output
