MIST55 RTD Pt 100 Thermowell Temperature Sensor Transmitter is a complete RTD temperature sensor probe, signal conditioner and 4-20mA output. You provide the 12 to 36 Vdc loop power. The Intempco MIST patented RTD (Pt100) sensor probes contain the temperature transmitter within the probe assembly.

The transmitter is hermetically sealed from moisture or contaminants and provides tamper-proof vibration resistance. The 2 wire 4 to 20mA output is stable and accurate.

MIST transmitters are shipped at the factory calibrated temperature range, selectable via the ordering code. If it becomes necessary to re-calibrate or re-range the MIST the MIST PKit-2 USB is a quick and easy software tool. Calibration using a temperature bath is not required.

The MIST55 has a spring loaded probe and is designed to fit snugly into the bottom of a thermowell. Contact us to discuss correct thermowell ordering and to determine the correct length thermowell.
