With gauges being vital to any vacuum system in order to efficiently control and monitor processes, you can find a wide selection of technologies to best suit your application. From Active to Passive and 2000mbar to 1e-12mbar we have the solution for you.
In all cases we offer gauges that span the complete range from Atmosphere to UHV pressures
Capacitance manometer gauges are the most accurate “active” gauges we sell, with accuracies of <1% and the ability output a linear 0-10V signal or communicate via RS232. They are Electro-mechanical gauges using a ceramic membrane to form an electrode of a capacitor. Available in a number of temperature controlled variants, our new Capacitance range can be integrated into many applications where accuracy is key.
Active gauges are a complete self-contained head and driver electronics in a compact unit. These gauges typically need 24 V dc and then provide a 0-10 V output that relates to the pressure. This output can be S-shaped or Linear depending on the chosen unit
Digital gauges are similar to Active in that they are self-contained including driving electronics, however they take this one step further and eliminate the need for a separate controller. The Digital gauges simply need a supply voltage in the range of 15 to 48Vdc and then are serial comms enabled, so can be directly interrogated via a PC or PLC using either RS232 or RS485 communications.
Passive gauges completely separate the measuring part from the driver electronics. The head that is attached to the system only contains the items needed for the physical measurement and all other electronics is contained in the controller. As such the controller and cable have to be specific to the desired gauge.
Portable gauging offers the opportunity to be free of cabling and power and take spot measurement checks. The Edwards P3 handheld all in one measuring system is the essential device for on-site service calls and on the spot flexible checking due to it being mains power independent
