Using the free ConSoft software, the 4…20 mA device can easily be configured from a PC, also in hazardous areas. Parameters like temperature measurement range, TAG identity and failure indication can be set and re-set fast and convenient thanks to a user-friendly interface. High accuracy over transmitter lifetime is provided by a measuring accuracy of ±0.08 °C or ±0.08 % of span, and a drift of ±0.01°C per 1 °C or ±0.01% of span per 1 °C. This low temperature drift makes regular calibration less necessary.
In terms of safety and reliability, OPTITEMP TT 33 C/R is compliant to NAMUR recommendations (NE) 21, 43, 53 and 107, and features ATEX and IEC Ex approvals. Due to a robust construction, external influences such as ambient temperature, vibration (up to 10 g, as may occur in OEM/machinery applications), moisture and electromagnetic waves are negligible.
The new transmitter can provide correction for measuring error of the system consisting of either the sensor itself or sensor and transmitter together. OPTITEMP TT 33 C/R also features a runtime counter, tracking and backup of previous configuration, ambient temperature log as well as an output simulation for loop testing.
OPTITEMP TT 33 C/R adds to KROHNEs OPTITEMP portfolio of industrial temperature assemblies and transmitters. It comprises a large choice of designs, materials and process connections from high to cryogenic temperature applications. Standard as well as custom versions are available for solid, liquid and gaseous mediums, also with high pressures and flow velocities.
