賀德克溫度傳感器ETS 1700電子溫度開關主要用于與專為油箱安裝而開發的溫度探頭TFP 100配合使用。
4位數字顯示屏可顯示實際溫度、一個開關點或***高溫度值。
***高溫度表示設備接通或上次重置以來出現的***高溫度。
這四個開關輸出可用于控制液壓系統中的加熱和冷卻過程，例如。通過按鍵板，可以非常簡單地調整四個獨立的開關和開關回位點。
為了集成到監控系統（例如，與PLC配合使用），還提供模擬輸出（4 .. 20 mA或0 .. 10 V）。

Setting Options
|
The microprocessor integrated into the ETS 1700 enables many useful extra functions in addition to the switching functions, when compared with a normal mechanical temperature switch. It is possible, for example, to activate switching delay times or to change the relay switching direction. All settings are made via the key pad. |
Additional Setting Options
|
- Switching direction of the relays 1 to 4 (N/C or N/O)
- Switch-on delay relays 1 to 4 in the range 0.00 .. 90 seconds
- Switch-off delay relays 1 to 4 in the range 0.00 to 90 seconds
- Switch-back mode (either switch-back point or switch-back hysteresis)
- Display of the actual pressure, a switching point or of the peak value
- Display filter (slow/medium/fast)
- Display range scale individually adaptable (Fahrenheit, Celsius, user-selectable)
- Measurement unit (Celsius, Fahrenheit) is displayed
- Analog output (4 to 20 mA or 0 to 10 V)
- Programming disable
|
Setting Ranges of the Switching Points
|
- Switching point relay 1 to 4: 1.5 % to 100 % FS
- Switch-back relay 1 to 4: 1 % to 99 % FS or alternatively switch-back hysteresis 1 to 4: 1 % to 99 % FS
|
|
Reverse polarity protection of the supply voltage, excess voltage, override and short circuit protection are provided.
