The OPTITEMP TT 51 R is a universal, programmable high-performance 2-wire rail-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). The device is available in 2-, 3- or 4-wire circuit. It also features the option of a 4-wire circuit for two Pt100 inputs. The transmitter 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 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.
The OPTITEMP TT 51 R is SIL2 approved (IEC 61508) and thus the ideal solution for use in Safety Instrumented Systems (SIS). The temperature transmitter is also available as intrinsically safe. As an added bonus, the ConSoftTM configuration software makes the transmitter start-up particularly simple. The temperature transmitter is designed to be mounted on a DIN rail. A dedicated head-mounted version is available with the OPTITEMP TT 51 C.
