燃气压力开关DG
特点:
●可控制燃气及空气压力
●可实现负压和低电压切断燃气、空气管路
●压力调节刻度显示
●H及N型带有非自锁复位按钮
●根据实际要求有特殊设计的压力开关
●适用于生物甲烷气体 通过上表可以看出运用DG可以实现正压、负压、及差压控制。差压的控制需连接在相应阀体设备前后(如孔板前、后的导压管)且在不同的状况选择控制时需要在该设备上连接不同的空位置,其需注意导入介质的要求(燃气及混合燃气不可导入,烟气不可含腐蚀性成分)

Applications Food and beverage industry Pharmaceutical industry Filling and packaging machinery Sanitary applications
Special features Easily-readable, robust display Intuitive and fast setup Easy and flexible mounting configurations Description
Award-winning in design and functionality The successful design and the excellent functionality of the WIKA switch family were already confirmed by winning the "iF product design award 2009" for the PSD-30 pressure switch. The robust LED display has been designed using 9 mm high characters (the largest possible) and with a slight incline in order to make reading the pressure as easy as possible from a long way off. A 14-segment display has been used, since it represents text very well.
The 3-key operation makes simple, intuitive menu navigation possible, with no need for additional assistance. The menu navigation is designed in accordance with the latest VDMA standard. The VDMA standard for fluid sensors (24574-1, part 1 - pressure switches) has the aim of simplifying the use of pressure switches by standardising menu navigation and display. The control keys have been designed as large as possible and are arranged ergonomically to ensure fast and easy adjustments. Operation without any additional assistance is made easier through the tactile feedback.
Customised installation The installation of the PSA-31 can be flexibly adapted to the individual mounting situation. Due to the almost unlimited rotation of the display and case by more than 300°, the display can be adjusted independently of the electrical connection. The display can thus always be aligned to face the operator, and the M12 x 1 connection positioned to suit the desired cable routing.
High quality During development of the WIKA switch family a high value was placed on a robust design and the selection of appropriate materials suited to machine building applications. For this reason the case and the threaded connection of the electrical connector are made from stainless steel. Overwinding or tearing off the connector is therefore virtually impossible.
