The Optitemp TT 51 temperature transmitter from Krohne is especially designed for use in the chemical industry. In keeping with industry requirements, the transmitter guarantees accurate measurements over the long term and superior reliability. For use in safety-related applications, it features SIL2 approval as per IEC 61508. Its electronic system boasts a long-term measuring error of just 0.05% of the span. The SmartSense insulation monitoring detects moisture in the measuring insert. If the measuring insert (and the sensor element) absorbs moisture, the electrical isolation resistance immediately decreases, resulting in a measurement error. This safety risk can thus be quickly detected and eliminated. A second, redundant sensor can be connected to the transmitter by way of a dual input. The device is either mounted directly to the measuring insert (head-mounted transmitter) or it is installed separately in a control cabinet as a rail-mounted transmitter. The head-mounted version is particularly robust. External influences such as the ambient temperature, vibrations, moisture and electromagnetic waves have no significant impact on the measuring result.
