EDS 3400是一款集成数字显示的紧凑型电子压力开关，用于在高压范围内进行相对压力测量。为此提供带有薄膜DMS的不锈钢测量元件。该设备具有1或2个开关量输出和一个可逆模拟量输出信号（4 ... 20 mA或0 ... 10V）。 EDS 3400的一个特殊功能是可以在2个轴上旋转显示器。该装置可以在几乎任何随机的安装位置上*地对准，这意味着通常需要的机械对准适配器的附加成本被省去。 4字符数字显示器可以显示bar，psi或MPa的压力。用户可以在不同的单元之间进行选择。使用此功能，设备会根据新设备自动重新调整开关设置。另外，EDS 3400也可以使用符合DESINA?的变型。带有前平板隔膜的变型专门针对使用介质会导致堵塞，上胶或冻结标准压力连接的应用而开发。

EDS 3400

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.
