Available versions:
Standard; in conformance with DESINA®; Menu navigation in accordance with VDMA; with front-flush diaphragm
The EDS 3400 is a compact electronic pressure switch with integrated digital display for relative pressure measurement in the high-pressure range. It is provided for this purpose with a stainless steel measuring cell with thin-film DMS. The device has 1 or 2 switching outputs and one reversible analogue output signal (4 ... 20 mA or 0 ... 10V). A special feature of the EDS 3400 is the option of rotating the display in 2 axes. The device can be optimally aligned in practically any random installation position, which means that additional costs for the mechanical alignment adapter which is usually required are dispensed with. The 4-character digital display can show the pressure in bar, psi or MPa. It is possible for the user to select between the different units. With this function, the device re-scales the switching settings automatically in accordance with the new unit. In addition, the EDS 3400 is also available in a variant which conforms to DESINA®. The variant with the front-flush diaphragm was specially developed for applications in which the media used could lead to a blockage, gumming-up or freezing of a standard pressure connection. The main applications of the EDS 3400 are to be found primarily in hydraulics, pneumatics and in refrigeration and air-conditioning technology. Further applications include processes where the medium changes frequently and any residues could cause mixing or contamination of the media.

壓力繼電器工作原理
壓力繼電器是利用液體的壓力來(lái)啟閉電氣觸點(diǎn)的液壓電氣轉(zhuǎn)換元件。當(dāng)系統(tǒng)壓力達(dá)到壓力繼電器的調(diào)定值時(shí),發(fā)出電信號(hào),使電氣元件(如電磁鐵、電機(jī)、時(shí)間繼電器、電磁離合器等)動(dòng)作,使油路卸壓、換向,執(zhí)行元件實(shí)現(xiàn)順序動(dòng)作,或關(guān)閉電動(dòng)機(jī)使系統(tǒng)停止工作,起安全保護(hù)作用等。
壓力繼電器有柱塞式、膜片式、彈簧管式和波紋管式四種結(jié)構(gòu)形式。下面對(duì)柱塞式壓力繼電器的工作原理作一介紹:
當(dāng)從繼電器下端進(jìn)油口3進(jìn)入的液體壓力達(dá)到調(diào)定壓力值時(shí),推動(dòng)柱塞2上移,此位移通過(guò)杠桿放大后推動(dòng)微動(dòng)開(kāi)關(guān)4動(dòng)作。改變彈簧1的壓縮量,可以調(diào)節(jié)繼電器的動(dòng)作壓力。
應(yīng)用場(chǎng)合:用于安全保護(hù)、控制執(zhí)行元件的順序動(dòng)作、用于泵的啟閉、用于泵的卸荷。
注意: 壓力繼電器必須放在壓力有明顯變化的地方才能輸出電信號(hào)。若將壓力繼電器放在回油路上,由于回油路直接接回油箱,壓力也沒(méi)有變化,所以壓力繼電器也不會(huì)工作。根據(jù)所測(cè)對(duì)象的壓力來(lái)選用,比如所測(cè)壓力范圍在8KG以?xún)?nèi),那么就要選用額定10KG的壓力繼電器,還有要符合電路中的額定電壓,接口管徑的大小
