可視壓差指示器可使操作者在插入元件前讀取污染積聚程度。 指示器安裝在濾清器的頭部位置。 該指示器具有自動回零功能。 標準結構為不銹鋼。 標準壓力設定為 40 PSID。
TESCOM減壓閥編號 E - Electrical P 電子指示器在現場讀取數字有困難或需要集中監控系統裝置的場合下,電子可視壓差指示器是理想選擇。 將指示器接入中央控制臺,就可以對濾
清器進行方便快速的遠程監控。 ΔP 電子指示器安裝在濾清器的頭部位置。 結構材料為 303 不銹鋼。 ΔP電子指示器帶一常開的可調開關,可控制信號裝置。 當 ΔP 增大時開關觸點閉合,當
ΔP 減小時則自動歸零。 電子指示器的連接使用一 3/4" 凸管件接頭。 電壓要求: 10W - DC, 110 VA - AC 接通電流為 0.。 高負荷情況的繼電器要求。

當供應轉換TESCOM調節器的主壓力源 A 消耗完后,第二級壓力源 B 繼續向管道TESCOM調節器及/或應用工序提供壓力介質。 管道TESCOM調節器按要求的精確壓力向應用工序提供壓力介質。 順時針方向旋轉TESCOM調節器旋鈕可向 A 處補充壓力介質。 當 B 處的壓力介質消耗完之后,A 開始繼續對管道TESCOM調節器及/或應用工序供應。 逆時針轉動轉換TESCOM調節器旋鈕,可補充 B 處的壓力介質。

編號 R – 旁通安全閥
在預先設定的條件下,系統中的流體介質不流過濾清器,直到部件被清洗或更換。 標準設定: 50 PSID 開啟壓力。
編號 V – P 指示器
可視壓差指示器可使操作者在插入元件前讀取污染積聚程度。 指示器安裝在濾清器的頭部位置。 該指示器具有自動回零功能。 標準結構為不銹鋼。 標準壓力設定為 40 PSID。
