Description
The Automation Components Inc (ACI) 123301 6″ Thermistor Immersion No Well is a temperature sensing probe to measure liquid temperature in hydronic piping and water-based circuits. It features a 10K Ohm thermistor element housed in a 6-inch probe designed for direct immersion without a thermowell. This sensor is commonly applied in boilers, chilled water lines, and hot water loops during monitoring or control replacement work. It provides resistance-based temperature feedback to control assemblies, supporting accurate temperature regulation and system monitoring in residential and light commercial HVAC systems.
