Field of application
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.
Temperature transmitter with secure Bluetooth® and HART® 7 communication
Backlit display for clear process and diagnostic information in the field
Universal input for resistance sensors (RTD), thermocouples, resistances (Ω) and voltage transmitters (mV)
Reliability, long-term stability and high precision for safe operations in critical processes
Robust aluminum or stainless steel housings for use in hazardous areas and harsh process conditions
Benefits
Certified for use in hazardous areas:
CSA (IS, NI, XP and DIP), ATEX, INMETRO, NEPSI (Ex ia, Ex d, dust ignition-proof)
Reliable, long-term stable and accurate temperature measurement even under harsh environmental conditions thanks to a pressure-encapsulated single-chamber housing and integrated overvoltage protection
Bluetooth® interface: Save time and effort on commissioning, configuration and maintenance using the Endress+Hauser SmartBlue app
Predictive maintenance with advanced diagnostic functions and condensed status notification according to NAMUR NE 107
Newly developed backlit display with large digits for clear process information under all ambient conditions
