ExTempMini: New ATEX Pyrometer for High Ambient Temperatures

Temperature Measurement, , , , , , ,

The new ExTempMini is an intrinsically safe two-piece pyrometer with a sensing head that can be used in high ambient temperatures, up to 180°C. The sensor is ATEX, IECEx, UKCA and JapanEx certified for all surface gas Zones up to Zone 0 (sensing head) and Zone 1 (electronics module).

The sensor has a two-wire 4-20 mA output and is fully configurable via the LCT and LCT-485 interfaces.

For specifications, including full details of the hazardous area classification, see the ExTempMini on the Calex website and the ExTempMini data sheet. 

Sensors are available to order now. Contact us to discuss your application.

 

New RS-485 Network Interface for ExTemp sensors now available

The new LCT-485 network interface for ExTemp intrinsically safe infrared temperature sensors is now available to order!

It is designed to be connected on the safe side of an Intrinsically Safe barrier or isolator, and allows multiple ExTemp sensors to be monitored and configured digitally on the same RS-485 Modbus RTU network.

The LCT-485 features automatic baud rate detection for use with a variety of Modbus Masters.

Each LCT-485 provides communications for one ExTemp sensor. Up to 224 LCT-485 devices may be connected to a single Modbus Master.
