(14)The ETS 3200 is a compact electronic temperature switch with digital display.
With its integrated temperature probe, the ETS 3200 is particularly suitable for direct tank installation and is available in various lengths.
Different output models with one or two switching outputs, optionally with an additional analog output signal, offer a variety of application possibilities.
The switching points and the associated hysteresis can be adjusted very quickly and easily using the keypad./Asset/ETS_32XXTempSwitch.jpg
(4)The ETS 3800 is a compact electronic temperature switch with a 4-digit display.
The version for a separate temperature probe has a measuring range of -22..+302 ºF and is used primarily with the TFP 100 temperature probe which was specially developed for tank installation.
It is also possible, however, to evaluate commonly-available PT 100 temperature probes.
Different output versions with one or two switching outputs, and with the possible option of an additional analog output signal, offer a variety of application possibilities.

(2)The electronic temperature switch ETS 1700 is used mainly together with the temperature probe TFP 100, which was specially developed for tank mounting.
The 4-digit display can indicate the actual temperature, one of the switch points or the maximum temperature value.
The maximum temperature indicates the highest temperature which has occurred since the unit was switched on or was last reset.
The four switching outputs can be used to control heating and cooling processes in hydraulic systems, for example. Four switch and switch-back points which are independent of each other can be adjusted very simply via the key pad.
For integration into monitoring systems (e.g. with PLC), an analogue output (4 .. 20 mA or 0 .. 10 V) is also available./Asset/ets1700.jpg
(3)The TFP 100 temperature probe was developed primarily for tank installation. The PT 100 precision resistor in 4-conductor design can be connected directly to HYDAC temperature switches ETS 3800, ETS 380 and ETS 1700.
The standardized electrical connection also means that other evaluation or control systems (e.g. PLC) can easily be connected.
For adaptation to different applications and fluids, a nickel-plated brass installation sleeve which is pressure-resistant up to 10 bar is available as an accessory./Asset/TFP 100 picture.jpg
