ETS 380 Electronic Temperature Switches for separate temperature probe

The ETS 380 is a compact electronic temperature switch with a 3-digit display.

The version for a separate temperature probe has a measuring range of -22..302 °F 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 models with one or two switching outputs, and with the possible option of an additional analog output signal of 4 .. 20 mA open up a multitude of application opportunities.

The switching points and the associated hysteresis can be adjusted very quickly and easily using the keypad.

For optimum adaptation to the particular application, the instrument has many additional adjustment parameters (e.g. switching delay times, N/C / N/O function, etc.).

Special features:

• 2 transistor switching outputs, up to 1.2 A load per output
• Optional analog output signal 4 .. 20 mA
• 3-digit display
• Switching point or window function
• Switching / switch-back points and many useful additional functions can be set using the keypad

Setting options:

All the settings available on the ETS 380 are combined in 2 easy-to-navigate menus. To prevent unauthorized adjustment of the instrument, a programming lock can be set.

Setting ranges of the switching points and switch-back hysteresis:

Switching point function

Window function

All ranges given in the table are adjustable by the increments shown.

Additional functions:

• Switching mode of the switching outputs adjustable (switching point function or window function)
• Switching direction of the switching outputs adjustable (N/C or N/O)
• Switch-on and switch-off delay adjustable from 0 .. 750 seconds
• Choice of display (actual temperature, peak temperature, switching point 1, switching point 2, display off)
