    QM20-E-S / Ethernet / Standard Resolution

    EDFelectronics offers so called PC based thickness rate monitors QM20 series, which combine the functionality of an oscillator and measurement converter. All monitors are installed between sensor head and superior control unit (e.g. PC or PLC) on atmosphere. The transducer delivers information about quartz frequency, with extremely high accuracy and temperature stability rate via a serial line like RS232, RS485, USB or PoE QM20 series are available with standard and high resolution.
