德國HYDAC特點
a.檔次高：采用電子式壓力開關(guān)，內(nèi)置式DMS壓力傳感主件，可通過按鍵設(shè)定。精度高、壽命長、操作簡單；
b檢測精度可達0.5%，適用于多種工作領(lǐng)域;
c. 產(chǎn)品穩(wěn)定性能好：在設(shè)計中加入了特別的補償線路，將偏差控制在極小的范圍內(nèi)，使產(chǎn)品在正常使用中，保持很好的穩(wěn)定性;
d. 使用方便：機械電氣連接簡單，可通過按鍵設(shè)定，輸出信號可直接輸入PLC控制系統(tǒng);
e壽命長：采用電子開關(guān)實現(xiàn)了無觸點控制，與機械觸點式開關(guān)相比壽命長.

The programmable electronic pressure switch of the series EDS 4300 was specially developed in order to combine the advantages of a compact, robust and inexpensive device with the virtues of a programmable pressure switch. The EDS 4300 can be programmed conveniently and simply with the HPG 3000 programming device. If the connection between the programming device and the EDS 4300 is separated, then all of the settings will remain in effect in the pressure switch. This prevents the possibility of unauthorised or incorrect modification of the settings being made. The following parameters can be modified: - Switchpoint - Hysteresis - Switching direction (closer / opener) - Switching delay times The EDS 4300 is suitable for low-pressure applications (up to 16 bar) and is equipped with a pressure measurement cell with thick-layer DMS on a ceramic diaphragm. In comparison with the customer-specific permanently set pressure switches, the programmable EDS 4300 reduces the number of variants, which has a positive effect in terms of warehouse storage.
