930.8xdifferential pressure switch is high performance, high quality differential pressure switch. These DP switch can be used for monitoring over-pressure, vacuum and differential pressure of air or other non-combustible, non-aggressive gases.

where x is:

• 0 = 20-300 Pa with switch differential of 10Pa (0.2 to 3 mbar)
• 3 = 50-500 Pa with switch differential of 20Pa (0.5 to 5 mbar)
• 5 = 200 1000 Pa with switch differential of 100Pa (2 to 10 mbar)

930.8x comes with high repeatability changeover switch to enable pressure control and automation, thus find many applications in HVAC area. Eg. filter status monitoring, AHU pressure / flow monitoring and so on.

Most important feature of Beck 930.8x, is its adjustable switching knob, thus user can set switching contacts at any required differential pressure. This peculiar feature makes pressure switch highly versatile, and thus can be used in many control topology in HVAC and air applications.

Stainless steel, corrosion resistant diaphragm for non-corrosive and aggressive liquids, gases mediaMake: Fischer Messtechnik (Germany)Model: DA08

Fischer DA08 is high accuracy gauge for measuring low and lowest level differential pressure, absolute pressure and partial vacuum pressure of non-aggressive and clean gaseous media. These are mainly suitable for installation in industrial and climate control application eg. pharmaceutical, biotechnology, clean rooms, HVAC, data centres, laboratory, kitchen etc.

A capsule element measuring system is installed into a pressure-tight housing.The higher pressure acts on the inside of the capsule element, the lower pressure is lead into the pressure-tight housing.

The differential pressure arising between the internal and external side of the measuring system leads to a deformation of the capsule element. This movement is turned into a scaled measured value indication via the motionwork.
