New multi-pyrometer system with data logging

Paul Boughton

The new PM180 touchscreen pyrometer hub from Calex Electronics provides temperature measurement, configuration, alarm display and data logging for up to six non-contact infrared temperature sensors, and may be connected to other PM180 units as part of a larger system.

The Calex sensors are connected in a daisy-chain via the RS485 Modbus interface, and the password-protected touchscreen interface of the PM180 allows full configuration of each sensor.

The bright, backlit display shows all six measured temperatures simultaneously, and the background of each temperature turns bright red in an alarm condition. Optional output modules provide alarm relay and analogue (current or voltage) outputs. Each output may be individually configured via the touchscreen.

Data is logged to a MicroSD Card in .csv format so it can be imported easily into spreadsheet software such as Excel. Multiple PM180 units may be connected to a larger RS485 Modbus network using the isolated slave interface.

The wall-mountable touchscreen unit is tested to industrial standards for electromagnetic compatibility. It is CE Marked and RoHS compliant. The PM180 is compatible with all sensor models in the PyroBus series, as well as all Modbus models in the PyroMini series.
