About ETS 1700 Temperature Switches:
The electronic temperature switch ETS 1700 is used together with the temperature sensor TFP 100, which was specifically developed for tank mounting. The 4 digit display can indicate either the actual temperature, one of the switching points, or the maximum temperature. The maximum temperature indicates the highest temperature which has occurred since the unit was switched on or last reset. The 4 switching outputs can be used to control heating and cooling processes in hydraulic systems, as an example. All switching and switch-back points, which are independent of each other, can be adjusted very simply via a membrane keypad. For incorporation into monitoring systems (e.g. with PLC), an analog output (4 to 20 mA or 0 to 10 V) is also available.
