Pirani Thermal Vacuum Gauge > Measures: 1 x 10-4 to 1,000 Torr > Traditional Logarithmic Analog Output > Works in Any Installation Orientation > Easy to Install and Operate > Simple Push Button Zero and ATM Adjustment The HVGpr vacuum gauge from Teledyne Hastings Instruments features a thermal-based Pirani sensor in a compact package. The Pirani sensor is a precision welded hot-wire thermal sensor that measures pressures from 1 x 10-4 to 1,000 Torr. This proven Pirani sensor design has been used in high-volume production of the HVG-2020B Piezo/Pirani vacuum gauge since 2019. The HVGpr was designed with convenient features for system integration. Available system connections include KF-16 Flange or 1/8" MNPT connection. Both system interfaces are small, low cost and perfect for OEM designs. The HVGpr also offers two choices for analog output signal: 1V/decade logarithmic (2-9 VDC) or 1.286V/decade logarithmic (1.16-10.1620 VDC). These output curves allow you to measure seven decades of vacuum with distinguishable resolution. In addition, RS485 digital communication is always available. The RS485 communication allows you to query pressure, change analog output configuration, change gas selection and much more. All power, analog signal and digital connections are made with a single RJ45 connection. RJ45 connectors are simple to use and hardware is commercially available anywhere. While it is always recommended to install vacuum gauges with the port facing downward, the HVGpr can be installed in any orientation in your system and maintain accurate measurements. Finally, the HVGpr has a compact design that is optimized for small enclosure OEMs. Vacuum Furnace/Heat Treat Freeze Drying HVAC & Refrigeration Oil Reprocessing • Analytical Instrumentation • Foreline Monitoring • Thin Film Coating ^TELEDYNE I Hastings Instruments
