Product Specification

PSC-SSS (Smart Small Sensor)
Precise non-contact temperature measurement from -50°C to 975°C

PSC-SSS-LT Infrared Temperature Sensor Description
The PSC-SSS IR temperature sensor series is a highly versatile low cost solution for reliable temperature measurement. It features a temperature range of -50° to 1800°C which is fully scalable by an operator via programming keys, or by use of the included, no cost PSC Connect software. Other IR sensor parameter adjustments include peak picking, valley hold, average, and extended hold function with threshold and hysteresis.

The sensor head can be installed in higher ambient temperature, and a full line of rugged industrial accessories is available for its protection and optimum operation. Its small size facilitates temperature measurement in not easily accessible areas and simplifies integration into existing manufacturing systems. All PSC-SSS Sensors feature a choice of outputs including 4 to 20 mA, thermocouple, and linear voltage. Optional digital outputs include USB, RS-232, RS-485, CAN, Profibus DP and Ethernet. Programmable functional inputs for external emissivity adjustment, ambient temperature compensation and trigger reset of hold functions are provided.
