Networked Infrared Thermometers

Sept. 1, 2011
MI3 series of multichannel non-contact infrared temperature measurement sensors help gather critical operation temperature data for use in applications requiring digital communication for field devices.

The sensors, which are compatible with the Modbus and Profibus network protocols, combine a rugged IP65 (NEMA 4) stainless steel sensing head with a separate communication module. They include a choice of sensing head temperature ranges and spectral responses, as well as a standard USB 2.0 digital interface for troubleshooting. The sensors’ multiple sensing head interface supports up to eight individually addressable heads per communication box and feature response times as fast as 20 mS. For integration into existing control equipment or OEM systems, the sensors offer a choice of scalable 0/4 to 20 mA and 0 to 5/10 V dc analog outputs, or Type J, K, R or S thermocouple outputs, as well as an optional RS485 network interface. The MI3’s optically isolated relay allows for local alarm capability, eliminating the need for separate limit switches or alarms.
