Overview
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.
