Calex Electronics announced that its ExTemp intrinsically safe infrared temperature sensor can now be connected digitally in multi-point installations via a new RS-485 Modbus network interface. This opens up new possibilities in applications such as automotive paint curing. Temperatures in hazardous areas, including Zones 0 and 20, can be measured with these ATEX, IECEx, TIIS and UKCA (from 1 Jan 2021) certified sensors.
Multiple locations can be connected with a single network bus cable, cutting costs and simplifying the installation
The new LCT-485 is a DIN-rail mounted unit providing digital RS-485 Modbus RTU communications with an ExTemp sensor via a suitable safety isolator or zener barrier in the safe area. Automatic baud rate and bit format detection allows use with almost any third-party Modbus Master.
