The TM-950 Series temperature sensors use an open (exposed) thermistor design for faster response to temperature fluctuation than with closed (encapsulated) designs. The sensors can be used to monitor temperatures in any nonconductive fluid. Glass is fused inside the sensor housing, and inductive soldering around the thermistor leads to produce a hermetic seal. Leakage is eliminated while taking advantage of the quick responsiveness of an open, direct contact thermistor.
