The OPTITEMP TT 51 C is a universal, programmable high-performance 2-wire head-mounted temperature transmitter with HART® communication. The galvanically isolated dual input device works with RTD elements, thermocouple (TC) elements or other inputs (mV and Ω) in 2-, 3- or 4-wire circuit. It stands for proven stability, reliability as well as high accuracy and boasts a minimum measuring error of ±0.05% of span in 5 years. The HART® transmitter offers extended diagnostic information (e.g. open or short circuit monitoring etc.). Its unique ''SmartSense'' function allows insulation resistance monitoring to prevent measuring errors.
