Features

COLOR DISPLAY WITH TOUCH PANEL. The HVG-2020A has an optional integrated touch panel color LCD
display. This gives the user easy configurability, stand-alone operation and local control over the instrument.
SUPERIOR ACCURACY. The output of the piezo-resistive sensor is thermally compensated and linearized to
provide accuracy of ± (0.1% of reading + 0.5 Torr), and better than ± (0.6% of reading + 0.5 Torr) over the
entire operating temperature range after zero adjustment.
GAS INDEPENDENT. The piezo-resistive sensor is media isolated and provides a direct pressure measurement
that is gas species independent.
300 SERIES STAINLESS STEEL. The vacuum envelope of the HVG-2020A is entirely 300 series stainless steel
with welded construction. Using metal seal vacuum connections eliminates the permeation, degradation and
outgassing problems of elastomer O-rings.
FLEXIBLE POWER REQUIREMENTS. The HVG-2020A can operate with any power supply capable of providing 12
– 36 VDC via the 9-pin D connector or a 2 mm bayonet jack connection.
DIGITAL COMMUNICATIONS. The HVG-2020A is equipped with RS232/RS485 and USB for digital
communications. The USB connector serves as a virtual COM port for serial communication, eliminating the
need for a USB to Serial converter.
ANALOG OUTPUTS. The pressure is available as a linear voltage or current analog signal. The 0-20 mA or 4-20
mA current option gives the user the advantages of a current loop output to minimize environmental noise
pickup and signal loss over long cable runs.
TTL ALARMS. Two alarm signals are provided with an open-drain configuration, one to indicate when pressure
goes above a value and the other below a value.
LED INDICATORS. Two LEDs provide instrument status and system pressure information.
