EDL STS series of calibrators were developed to produce a traceable calibration method for surface temperature readings. In order to calibrate the STS a method was required to establish a connection between the device and to a traceable standard. Simply calibrating a single RTD or thermocouple prior to insertion into a plate is unacceptable, as the thermal characteristics of the sensing device will depend on the method of insertion and quality of the fit.
A single sensor during calibration provides no measure of the heat flux within the block. Thermal interfaces and differences in thermal conductivity between the block and sensor prevent traceable calibration. The STS is supplied with a single reference thermocouple output that is modeled from the Reference thermocouples that are placed in precisely machined bores, to establish a consistent and precise fit between the thermocouple and block. These grounded metal sheath 1.52 mm diameter thermocouples, are used to set-up the STS and establish the calibration curve. They are removed after calibration and only the reference sensor is left in the block.
The STS-SC1 is designed for operation from ambient up to 650ºC, while the STS-SC2 is for operation to 350ºC.
