OPTITEMP TT 33 C – Head-mounted temperature transmitter

OPTITEMP TT 33 C – Head-mounted temperature transmitter

The OPTITEMP TT 33 C is a universal, programmable 2-wire head-mounted temperature transmitter. The galvanically isolated transmitter works with RTD elements, thermocouple (TC) elements or other inputs (mV and Ω). Due to its rugged design, it withstands external influences such as shocks and vibrations (up to 10 g, as may occur in OEM/machinery applications). With a fast step response time of just 0.15 s and high accuracy (±0.08 % of span) over transmitter lifetime, it is well suited for many industrial applications. Its low temperature drift (±0.01% of span) makes regular calibration less necessary. The temperature transmitter provides a temperature linear current output (4…20 mA). It is also approved for use in hazardous areas.

The OPTITEMP TT 33 C features various useful functions including runtime counter, tracking and backup of previous configuration, ambient temperature log, output simulation for loop testing as well as extended diagnostics complying with NAMUR NE 107. The head-mounted transmitter supports wireless Near Field Communication (NFC) as well as Bluetooth® communication. It can thus be remotely configured and monitored using mobile devices with the OPTICHECK Temperature Mobile app installed. Alternatively, the OPTITEMP TT 33 C can be easily configured from a PC using the ConSoft™ software with OPTITEMP TT-CON EX configuration kit. Thanks to the user-friendly interface, parameters like measurement range or failure indication can be set or re-set within seconds. The temperature transmitter is designed to be mounted in a "B connection head" or larger. As an alternative it can also be mounted on a DIN rail using an optional rail mounting kit. A dedicated rail-mounted version for DIN rails is available with the OPTITEMP TT 33 R.
