Smart temperature transmitter with Bluetooth

- Advertisment -

The new iTEMP TMT142B HART 7 temperature transmitters deliver highly accurate and reliable measurements, wireless communication via Bluetooth and user-friendly operation packaged in a robust single-chamber field housing. The technology offers significant improvements in process efficiency and plant availability while, at the same time, reducing costs.

To keep the effort for commissioning, device configuration and maintenance low, the transmitter features an integrated Bluetooth interface that enables users to wirelessly display measured and status values as well as to perform configuration tasks. The device is extremely easy and fast to operate using the company’s SmartBlue app. Access to the device is password-protected with the highest security standards. The device can be configured without needing to previously install device drivers, since they are part of the transmitter.

The newly developed backlit display provides excellent readability under all environmental conditions, both in the dark and in strong sunlight. Diagnostic messages are indicated by the display through variable backlight colour (white to red) and facilitate maintenance work in the field.

The conversion of different sensor signals into a stable, standardised output signal (4 to 20 mA) represents a challenge when it comes to industrial temperature measurement. Precision and long-term stability, particularly at critical measuring points, are crucial for safe and smooth process operations. 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.

The transmitter guarantees a high level of measuring point availability through integrated sensor monitoring functions and device diagnostics. Diagnostic information is available to the user in accordance with NAMUR NE 107, Condensed Status. The unit’s integrated overvoltage protection supports continued accurate measurement even after common upset events and protects the device against damage.

The transmitter-sensor matching capability using the Callendar-Van Dusen coefficients further improves the entire system’s temperature measurement precision.

This temperature transmitter, the latest addition to the complete offering of HART-compatible transmitters, is designed for safe operation in hazardous areas as certified by international approvals (ATEX, CSA C/US, IECEx).

Together with the SIL 2/3-compliant two-channel devices iTEMP TMT82 and iTEMP TMT162 and the single-channel iTEMP TMT72, Endress+Hauser offers the right device for all application scenarios. When paired with modular thermometers such as the new iTHERM ModuLine TM111 or TM131, the assemblies deliver innovative high-performance temperature measurement technology for both simple and extreme process environments.
