The HVG-2020A vacuum gauge from Teledyne Hastings is a media-isolated, gas composition independent, the piezoresistive instrument that provides accurate pressure measurement throughout the rough vacuum region.
The HVG-2020A is easy to install, and the optional display provides the users with several different views or modes of operation. The HVG-2020A is very flexible and can provide both analog and digital output to easily integrate into process control. A wide variety of linear analog output signals may be selected.
The Teledyne Hastings Instruments (THI) Reference Tube is an evacuated, sealed vacuum gauge tube accurately calibrated to precisely simulate a gauge tube at a given operating pressure. It is electrically equivalent to the metal and glass gauge tubes used with THI instruments. It permits quick and easy recalibration of THI Vacuum Gauge Indicators by merely plugging the instrument into the reference and adjusting the calibration “current set” potentiometer
until the instrument reads the exact pressure noted on the reference. THI Reference Tubes are available equivalent to most THI Gauge Tubes.
The HVG-2020B wide range, dual-sensor vacuum gauge takes measurement to the next level. With a Piezo based sensor and a thermal-based Pirani sensor accurately and confidently measure pressures across seven decades. The Piezo sensor is media isolated, gas composition independent, and periodically zeroed by the Pirani sensor. An ambient thermal sensor enables the instrument to adjust for temperature and therefore better accuracy.
The HPM 4/5/6 features a precision A/D converter along with a microprocessor to measure the thermocouple vacuum gauge tube’s signal output. The microprocessor converts the measurement to a pressure reading by employing the gauge tube’s well-defined output/pressure relationship. The result is displayed using a bright, easy-to-read graphical display. Tubes are matched and interchangeable without calibration adjustments.
