9820/9830-OWS傳感探頭監(jiān)周圍的電容有源探頭尖端域。 由于分離油分離器的體積增加是吸引到探探電容變化了。 種變化是用于激活報接口和控制繼電器。
特點和優(yōu)點
- 沒有移動件
- 標準的雙絞線程電子
- 現(xiàn)有的本安全屏危場所
- 四氟乙烯和不接液件
- 電容技術響應所有類型的油
- 電容技術不日常清潔
- 簡單的校準和控制置
Probe Mounted Level Switch W/ Diff. — 9820-OWS
The 9820/9830-OWS sensing probe monitors the capacitance field around the active probe tip. As the volume of separated oil increases in the separator or is drawn down toward the probe tip, the probe capacitance changes. This change is used to activate the relay for alarm interface and control.
Features and Benefits
- no moving parts
- remote electronics via standard twisted pair
- available with Intrinsic Safety Barrier for Hazardous Locations
- high corrosion resistant Teflon and stainless steel wetted parts
- capacitance technology responds to all oil types
- HF capacitance technology does not require routine cleaning
- easy calibration and control set-up
