See more clearly with the HVG-2020A Vacuum Gauge!

The HVG-2020A has a 9 pin D-sub connector on top of the assembly that allows an analog output signal to be measured amongst other features.  The selected linear analog output signal is proportional to the full scale range of the sensor (1000 Torr). Available outputs are 0-1 VDC, 0-5 VDC, 0-10 VDC, 0-20 mA, and 4-20 mA.  The sensor will come configured from the factory with one of these outputs active, but can be easily changed by the user should output requirements change.  Through the touchscreen display, there is a menu that allows the user to cycle through the available output options.  If the HVG-2020A was configured without a touchscreen, the analog output can be changed via digital communications, which we’ll talk about in the next section.  In addition to the analog output, the 9 pin D-sub will have Hi & Lo set points.  The Hi set point is active when the pressure is above the set value and the Lo set point is active when the pressure is below the set value.  Finally, the 9 pin D-sub has a pin for input power.  The HVG-2020A can accept 12-36 VDC for power.  In the event, the user doesn’t have 12-36 VDC to send via the 9 pin D-sub, there’s a 24 VDC input connection port that’s compatible with a bayonet-style power supply.

The most powerful feature of the HVG-2020A is the touchscreen display.  The intuitive display allows for quick visualization of the current pressure without needing to have a separate power supply or remote display. There are five available views to choose from (shown left to right below): Pressure View, Pressure & Temperature View, Set Point View, Bar Graph View, and Pressure over Time View.  The pressure is always displayed on each of these five screens.

There is also a menu button which will allow the user to cycle through a number of sub menus.  Through these menus the user can change the screen orientation should they mount the gauge in a position other than vertical, set the zero (this should only be performed if the system pressure is known to be well below 0.1 Torr), view device information such as serial number and firmware levels, change the analog output, cycle between RS232 or RS485 and a number of baud rates, and finally restore the configuration of the gauge back to the original factory setup.  The touchscreen display makes reading vacuum pressure as clear as 20/20 Vision!
