b检测精度可达0.5%，适用于多种工作领域;
c. 产品稳定性能好：在设计中加入了特别的补偿线路，将偏差控制在极小的范围内，使产品在正常使用中，保持很好的稳定性;
d. 使用方便：机械电气连接简单，可通过按键设定，输出信号可直接输入PLC控制系统;
e寿命长：采用电子开关实现了无触点控制，与机械触点式开关相比寿命长. 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.
