EDS 3300
Available versions:
Standard; in conformance with DESINA®; Menu navigation in accordance with VDMA; with front-flush diaphragm
The EDS 3300 is a compact electronic pressure switch with integrated digital display for relative pressure measurement in the low-pressure range. It is equipped in this connection with a ceramic measuring cell with a thick-layer 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 3300 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 3300 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 3300 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.

压力继电器工作原理
压力继电器是利用液体的压力来启闭电气触点的液压电气转换元件。当系统压力达到压力继电器的调定值时，发出电信号，使电气元件（如电磁铁、电机、时间继电器、电磁离合器等）动作，使油路卸压、换向，执行元件实现顺序动作，或关闭电动机使系统停止工作，起安全保护作用等。
压力继电器有柱塞式、膜片式、弹簧管式和波纹管式四种结构形式。下面对柱塞式压力继电器的工作原理作一介绍：
当从继电器下端进油口3进入的液体压力达到调定压力值时，推动柱塞2上移，此位移通过杠杆放大后推动微动开关4动作。改变弹簧1的压缩量，可以调节继电器的动作压力。
应用场合：用于安全保护、控制执行元件的顺序动作、用于泵的启闭、用于泵的卸荷。
注意： 压力继电器必须放在压力有明显变化的地方才能输出电信号。若将压力继电器放在回油路上，由于回油路直接接回油箱，压力也没有变化，所以压力继电器也不会工作。根据所测对象的压力来选用,比如所测压力范围在8KG以内,那么就要选用额定10KG的压力继电器,还有要符合电路中的额定电压,接口管径的大小
