These paired temperature sensors are used as components of energy meters. They are manufactured with the Pt 100, Pt 500 and Pt 1000 temperature sensing elements. The sensors are compatible with energy meters manufactured by SIEMENS, LANDIS + GYR, KAMSTRUP, ITRON, CODEA, COMAC CAl, SENSUS METERING, etc. The sensors are intended for installation in heat sinks. The standard operating temperature range is 0 ° C to 180 ° C or 0 ° C to 150 ° C.
