Immersion Temperature Probes

RTD & Thermistor Outputs, 304 SS Probes

TEMPERATURE

The Series I2-1 Immersion Temperature Probes are designed to monitor the hot and

chilled water lines throughout a building’s water distribution loop. The multiple
temperature sensor outputs allow these sensors to connect to virtually any digital building
controller. The Series IW2 SS thermowells allow the temperature sensors to be replaced
without draining the water line. The temperature sensors are available in 4˝ and 6˝
insertion lengths.

Note: A Series IW2 Thermowell must be used on pressurized air and water lines to
prevent leakage around the probe.
