Sensor Wiring - Siemens FUG1010 IP65 NEMA 4X Operating Instructions Manual

Clamp-on Sensors
Clamp-on style sensors are mounted on the surface of the monitored pipe using series
mounting assemblies. Apply a generous quantity of the thermal couplant provided to the tip
of the sensor and attach it securely to the cleaned pipe surface with the proper mounting
assembly. Temperature measurement anomalies resulting from variations in the ambient
conditions can be minimized by insulating the pipe and sensor after installation.

Insert sensors are designed to be used in pipes equipped with Thermowells. These are
spring-loaded, 1/4" diameter sensors with 1/2" NPT integral connection heads, available in
several lengths to accommodate a range of pipe sizes.
