The OPTITEMP TT 51 C is a versatile, programmable 2-wire head-mounted temperature transmitter with HART® communication. This galvanically isolated device accommodates RTD elements, thermocouples (TC) or other inputs (mV and Ω) in various circuits. With a minimum measuring error of ±0.05% of span over 5 years, it ensures stability and reliability. The HART® transmitter provides extended diagnostic information, including open or short circuit monitoring, while the "SmartSense" function prevents measuring errors by monitoring insulation resistance.
