The ETS 300 is a compact electronic temperature sensor with digital display. Two different models are available for optimum adaptation to particular applications.

The ETS 300 with built-in temperature sensor has a measuring range from -25 °C to +100 °C. It is pressure-resistant to 600 bar and can therefore be mounted directly on the hydraulic block, if required.

The model with a separate sensor input has a display range of -30 °C to +150 °C. The unit is mainly used together with the temperature sensor TFP 100 which was specially developed for tank mounting. However, commercially available PT 100 temperature sensors can also be used. Different output models with one or Iwo switching outputs, optionally with an additional analogue output signal 4 to 20 mA, offer a variety of application possibilities.

The switching points and the associated hystereses can be adjusted very quickly and easily via the membrane keypad. For optimum adaptation to the particular application, the unit has many additional adjustment parameters (e.g. switching delay times, N/C / N/C function of the outputs).

Special features:

Compact temperature sensor with integral or separate temperature sensor
2 transistor switching outputs, output capacity 1.2 A each
Option: analogue output 4 to 20 mA
Switching point function or window function
Many useful additional functions

Electronic Temperature Sensor | ETS 1600

Temperature range: 0 to 100 °C
Display range: 0 to 100 °C
3–digit temperature display: in °C
Accuracy: Better than 1.0 °C

Special features:

4 adjustable value contacts with relay output switching points and switch–back differential are freely adjustable, without opening the unit switch–back differential
0.5 to 20 °C switching point display via key command at any time without affecting the performance
Analogue output optionally 4 to 20 mA or 0 to 10 V safety type IP 65 can be combined with the pressure switch EDS 1600 of the same design.
PT 100 temperature sensor separately connected via a cable in the tank mounted immersion tube (4–conductor technique).
