MP-3189

Description: Our smallest thermistor with a 0.9 mm diameter sensor heat and 32 gauge wire. High accuracy tolerance of +/-0.1 °C within 0 °C to +70 °C range. Nominal 15K ohms resistance at 25 °C, provides a typical control range from -20 °C to +100 °C.  The thermistor can be mounted in a hole or on a surface. The wire leads can be extended with standard copper wire of any gauge recommended for the controllers (no special alloy necessary).

Description: Our smallest, high-accuracy thermistor with a 0.9 mm diameter sensor heat and 32 gauge wire. Nominal 15K ohms resistance at 25 °C, provides a control range from -20 °C to +100 °C. It offers a +/-0.1 °C tolerance within 0 °C to +70 °C.  Thermistor can be mounted in a hole or on a surface. The wire leads can be extended with standard copper wire of any gauge recommended for the controllers (no special alloy necessary).

This sensor features a high accuracy interchangeable tolerance corresponding to ±0.1°C over 0°C to 70°C. It has a small 0.9mm diameter, 6.35 mm long cylindrical head.  The resistance is 15K ohms at @ 25 °C (TS-67/ 15K-1 curve).  This temperature sensor provides a measurement range of -20 °C to +100 °C and works with all of our temperature controllers.  The thermistor can be mounted in a hole or on a surface.  

Wire is 32 gauge solid, overall length is 152 mm.  The wires have a thin varnish insulation (similar to magnet wire) and are not terminated.  Although delicate, these thin wires have an advantage in that they do not conduct much heat into the measurement head of the sensor, and they are easy to preheat or precool.  This helps ensure accurate temperature measurements.  We do recommend that if you will be bending the wire leads against a sharp metallic edge (such as when exiting a sensor hole) the wires be protected with a thin layer of epoxy or heat shrink so the edge does not cut through the varnish and electrically short the sensor.  Of course, you can radius to the sharp edge so it will not abrade the varnish.

Typically, a larger diameter wire is added to this thermistor as an extension to increase the overall distance from controller to measurement point.  The wire leads can be extended with standard copper wire of any gauge recommended for the controllers (no special alloy necessary).  The sensor does not have “fast-on” spade connectors on the end, so you must add wire and connectors if you wish to use this thermistor with the TC-24-10.
