www.teledyne-hi.comDescription & Specifications DESCRIPTION The Teledyne Hastings Instruments’ DAVC (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...
