The Teledyne Hastings DAVC-5 (Digital AVC) is a microprocessor based 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-5 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-5 - Digital Vacuum Controller The DAVC-5 includes several enhanced features which makes it an attractive solution for many vacuum control automation applications. The DAVC-5 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-5 provides RS232 communication for direct connection of the instrument to a computer.
