Digital thermometers solar operation / Marine version

The digital thermometers of the SolarTemp product series work with a discrete-time measuring method. The cycle time of the measurement starts from 3 sec, so that the operator can read the current measured value in passing. The SolarTemp has an easy-to-read LCD-based display. The instruments of the SolarTemp series have a robust mechanical construction and are designed for industrial use as well as for use under difficult environmental conditions. The IP65 protection class (front side) meets these requirements. The immunity to electromagnetic interference complies with the requirements of the applicable industry standards. After start-up, the instrument performs an internal self-test, checking the functionality of the connected sensor as well. Automatic diagnostic routines in the microprocessor permanently monitor the sensor signal for plausibility and can thus signal a sensor break via the display unit. The results are displayed as a message. By supplying the measuring instrument via the transmitter, the solar cell is only loaded in the event of failure of the current loop, thus providing a safe, independent local display.
