The piezo is used at higher pressures, above 10 Torr, to accurately measure pressures. This sensor is media-isolated and is also gas composition independent. The Pirani sensor is a precision welded hot-wire thermal sensor that measures pressures below 1 Torr. An ambient thermal sensor enables the instrument to make adjustments for temperature which in turn enables better accuracy throughout the pressure range of the instrument (0.1 mTorr to 1000 Torr). Between 1 and 10 Torr, a weighted average between the two sensors is used to determine the pressure. The HVG-2020B also features cross-calibration. In short, the low pressure Pirani is able to periodically zero the piezo sensor which gives the user superior accuracy performance. Display Modes The HVG-2020B is easy to install, and the optional display provides the user with several different views, or modes of operation. The "Pressure versus Time" Mode allows the user to monitor the pumpdown (or vent) of their vacuum system. In this mode, it can be possible to identify problems early and save time. Rate-of-rise can be viewed and may help to identify the presence of a chamber leak. For users who want another method to see system pressure changes, we provide the "Bar Graph" Mode. As the pressure changes, the user can view both the numeric value of the pressure in the system as well as the rate of change by viewing the position of the bar. Flexible The HVG-2020B is very flexible and can provide both analog and digital output to easily integrate into process control. A wide variety of analog output signals may be selected (0-1 VDC, 0-5 VDC, 0-10 VDC, 0-20 mA, and 4-20 mA). This makes the HVG-2020B an excellent choice to replace more expensive capacitance manometers. Digital output can include RS232 and RS485 via a small jack on the top of the instrument. A USB connection is also available which makes connection and operation very easy. Free Windows data acquisition software for data logging is available for the HVG-2020B.
