The WZP series industrial thermistor, as a sensor for measuring temperature, is usually used in conjunction with display instruments, recording instruments, and electronic regulators. It can directly measure the surface temperature of liquids, vapors, gases, and solids in the range of -200 ℃ to 420 ℃ during various production processes. The WZP series industrial thermistor is the most commonly used temperature detector in the medium and low temperature range.







Basic parameters: Measurement range: Platinum resistance Pt100-70~250 ℃ Copper resistance Cu50-50~100 ℃;
