Smart temperature.

Rugged field transmitter provides innovative functionality, improved measurement performance, and ease of use for applications in harsh environment conditions.

The iTEMP TMT142B, a new generation smart temperature transmitter with Bluetooth has been launched by Endress+Hauser. The transmitter delivers highly accurate and reliable measurements, wireless communication via Bluetooth, and user-friendly operation—all packaged in a robust single-chamber field housing. The technology offers significant improvements in process efficiency and plant availability while reducing costs.

In industrial process engineering applications, temperature transmitters are an important link between temperature sensors in the process and the higher levels of automation. Measurement instruments are often installed in difficult-to-access locations, which frequently makes commissioning, operation and servicing more difficult.

To address these and other issues, the transmitter features a highly secure integrated Bluetooth interface that enables users to wirelessly visualize measured values, NAMUR NE 017 diagnostic information, as well as perform configuration tasks. The device is extremely easy and fast to operate using your phone or tablet and the Endress+Hauser SmartBlue app. No special tools required. Access to the device is password-protected, and Endress+Hauser security provisions for Bluetooth communication complies with the highest standards.

The newly developed backlit display provides excellent readability under all environmental conditions, both in the dark and bright sunlight. Diagnostic messages are highlighted when the normally white background turns red.

The conversion of different sensor signals into a stable, standardized output signal (4 to 20 mA) represents a logistical challenge as it often requires multiple transmitter variations. To meet this challenge, the configurable single-channel device transmits converted signals from resistance sensors (RTD), thermocouples (TC), resistances (Ω) and voltage transmitters (mV) via the 4 to 20 mA signal or the HART 7 communication.

iTEMP TMT142B temperature transmitter is designed for safe operation in hazardous areas as certified by international approvals (ATEX, CSA C/US, IECEx). Safe operation is enhanced by the incorporation of an integrated overvoltage protection that protects the device from damage and permits continued functionality after common upset events.
