St. Louis-based Watlow Electric Manufacturing Co. introduced its Infosense sensor technology for thermocouples, which it claims is twice as accurate than standards, when coupled with the Watlow Series SD controller.
With Infosense, Watlow offers a set of four offset points that can be used to adjust the sensor calibration across the full temperature range. Standard thermocouples use single-point calibration correction, Watlow said.
The four calibration values are recorded on the thermocouple label and can be entered manually in the plant or read by a barcode reader tied to the communication port of the the Series SE controller.
