The single-channel iTEMP TMT142B temperature transmitter with backlit display delivers reliable, precise and long-term-stable measuring results under demanding conditions and in hazardous areas. It features a Bluetooth® interface for secure remote operation (Endress+Hauser SmartBlue app) and is equipped with a robust single-compartment field housing. It connects RTD, thermocouple (TC), resistance (Ω) or voltage (mV) signals and converts them into a 4...20 mA signal with HART® 7 communication.
Advantages
Numerous international approvals permit use in hazardous areas:
CSA (IS, NI, XP and DIP) and ATEX (Ex ia, Ex d and dust explosion protection)
Pressure-tight single-compartment housing with integrated overvoltage protection for reliable, long-term, stable and precise temperature measurement even under demanding conditions
Bluetooth® interface: use the Endress+Hauser SmartBlue app to save time and effort on instrument commissioning, configuration and maintenance
Advanced diagnostics and condensed status notifications support preventive maintenance in accordance with NAMUR NE107
Newly developed large-digit backlit display clearly shows process information under all environmental conditions
Application areas
Temperature transmitter supporting secure Bluetooth® and HART® 7 communication
Backlit display for clear on-site display of process and diagnostic information
Universal input signals for connecting RTD, thermocouple, resistance and voltage signals
High reliability, high long-term stability and high measuring accuracy for safe use under demanding conditions
Robust aluminum or stainless steel housing for safe use in hazardous areas or under demanding conditions
