iTEMP TMT142B: Temperature field transmitter with secure Bluetooth® communication using the CPace protocol

Remote device commissioning with SmartBlue

Smart, rugged, innovative: New generation temperature field transmitter with Bluetooth®

The single-channel iTEMP TMT142B transmitter with backlit display delivers highly reliable, accurate and long-term stable measurements in critical processes and hazardous areas.
It offers secure remote operation via its integrated Bluetooth® interface (Endress+Hauser SmartBlue app), packaged in a robust single-chamber field housing. It converts inputs from resistance sensors (RTD), thermocouple (TC), resistances (Ω) and voltage transmitters (mV) to a 4 to 20 mA signal and HART® 7 communication.
