The ACI Thermistor Pipe Mount Series features a 1.1” long Brass probe with a small curvature on the bottom that is designed to increase the surface area and improve the thermal conductivity between the pipe and the sensor. Each sensor has two, 24 inch 22 AWG Etched Teon colored lead wires to dierentiate the many dierent sensor types. All sensors in this series are manufactured using ACI’s proven double encapsulation process to eliminate the eects of moisture upon the sensors and to improve the thermal response times using our high quality, thermally conductive epoxy. The Pipe Mount sensor should be used to monitor pipe or coil sizes from 1/2” to 1” in diameter. A 7.5” nylon wire tie is supplied for fastening the sensor to the top of the pipe. For best accuracy and increased thermal conduction between the pipe and sensor, ACI recommends to clean the pipe and to apply thermal grease between the sensor and pipe before securely fastening to the pipe and insulating the sensor from any eects of the ambient air. An optional Plenum rated cable, Zip wire or NIST Certicate are available as referenced in the ordering grid on the back of the Product Data Sheet. Applications: Cooling Coils, Heating Coils, Hot Water Systems, Chilled Water Systems, Hydronic Heating Systems, Chillers
