The iTEMP TMT71 and TMT72 have an integrated Bluetooth interface that enables users to wirelessly display measured values and perform configuration tasks. Accessed through the company’s SmartBlue app, the temperature transmitters can be configured without the need to previously install device drivers, since they are already stored in the transmitter’s electronics. The configurable transmitters are compatible with signals from resistance sensors (RTD), thermocouples, resistance (Ω) and voltage transmitters (mV). They provide an output via the 4 to 20 mA signal or the HART 7 communication. Integrated sensor monitoring functions, device troubleshooting and diagnostic information in accordance with NAMUR NE 107, allowing for a high level of measuring point availability. The transmitter sensor’s precision of the temperature measurement is increased for the entire system as it matches calendar-Van-Dusen coefficients.
