Built for non-invasive pipe surface monitoring, this strap-on pipe temperature sensor clamps a 1.5" (3.81 cm) square copper plate to the pipe wall. In addition, a 1000 Ω nickel RTD element reads through the plate on 1-1/4 to 4" (32 to 100 mm) pipe, wired out of a plenum-rated ABS plastic enclosure. It suits retrofit chilled water and hydronic line monitoring.

The ACI Nickel Strap-On Series features a 1.5" square copper plate with the sensor encapsulated to the back side of the plate to improve the thermal conductivity between the pipe and the sensor when an Immersion style sensor can’t be inserted into the pipe in a retrofit application. Each sensor has two, 14" 22 AWG Etched Teflon colored lead wires to differentiate the many different sensor types.
The sensors in this series are manufactured using ACI’s proven double encapsulation process to eliminate the effects of moisture upon the sensors as well as to improve the thermal response times using our high quality, thermally conductive epoxy. The Strap-On Series sensors can be used to monitor pipe sizes from 1-1/4" to 10" in diameter.
For best accuracy and increased thermal conduction between the pipe and sensor, ACI recommends to clean the pipe before applying thermal grease and insulating the sensor from the effects of the ambient air. Optional Weather Proof enclosure and NIST Certificates are available as referenced in the ordering grid on the back of the Product Data Sheet.
Please contact ACI for more information regarding this sensor or to discuss your application in further detail. Other Options may be available upon request.
