TMT142: Universal HART temperature transmitter for use in the field

TMT162: Universal temperature transmitter with HART, PROFIBUS or FOUNDATION Fieldbus protocol.

iTEMP TMT142 HART temperature field transmitter has been purpose-designed to perform where the job demands. Industries such as chemical, petrochemical and mining pose their own set of challenges. That’s why the TMT142 offers a robust housing with IP65 protection and full ATEX approval.

The TMT142 is also universally programmable with HART protocol for resistance thermometers, thermocouples and voltage transmitters. The large rotatable rear-illuminated display shows the actual measured value, not only as a digital indicator but also as a 10% step trend bar graph for maximum operability. What’s more, the TMT142 fulfils NAMUR requirements: EMC to NE21, failure conditioning in the event of sensor breakdown to NE43 and corrosion detection to NE89. Operation, visualisation and maintenance are carried out via a PC, using FieldCare or ReadWin 2000 operating software.

The TMT162 is a two-wire transmitter with analogue output, two (optional) measuring inputs for resistance thermometers and resistance transmitters in 2-wire, 3-wire or 4-wire connection, thermocouples and voltage transmitters. The LCD display shows the current measured value digitally and as a bar graph with an indicator for limit value violation, The TMT162 (HART) can be operated using a handheld terminal (DXR375) or PC.
