Description

Temperature transmitters for head mounting

The iTEMP range of temperature head transmitters feature two input channels and a choice of HART (TMT82), PROFIBUS (TMT84) or FOUNDATION Fieldbus (TMT85) protocols for the conversion of different input signals into digital output signals. Resistance thermometers, thermocouples, resistance transmitters and voltage transmitters can all be fed through these compact devices and, for maximum versatility, they are suitable for use with 2-, 3- and 4-wire technology!

The iTEMP head transmitters also offer sensor diagnostics: sensor failure, cable corrosion, wiring error and device hardware error are all monitored for improved plant optimisation. Better still, with galvanic isolation between fieldbus and sensor inputs and ATEX, FM, CSA, IECEx and NEPSI certification for hazardous area use, you can be sure of accurate and reliable temperature data.
