The Teledyne Hastings Instruments' DAVC (Digital AVC) is a microprocessorbased vacuum gauge. In addition to the linear analog outputs (0-1 VDC, 0-5 VDC, 0-10 VDC, 4-20 mA, or 0-20 mA), pressure measurements can be accessed via the RS232 digital output. Digital readings can be provided in either Torr, mBar, or Pascal units.

A precision A/D converter, along with the microprocessor, measures the thermocouple vacuum gauge tube's output and converts the measurement to a pressure reading employing the gauge tube's well-defined output/pressure function.

The DAVC is a continuous-reading instrument for vacuum measurement and process control applications. The instrument is packaged in a small aluminum case with controls and electrical "D" connector located on the top.

DAVC - Digital Vacuum Controller:
The DAVC includes several enhanced features which makes it an attractive solution for many vacuum control automation applications. The DAVC can provide linear analog output (voltage or current) for integration of vacuum measurement with a PLC or other data acquisition system. In addition, the DAVC provides RS232 communication for direct connection of the instrument to a computer.
