Description
QM20-U-S it is PC based thickness rate monitor with USB interface and standard resolution of 0.1 Hz, 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 and are available with 2 inputs – one requires external oscylator – model QM-EO. The transducer delivers information about quartz frequency with extremely high accuracy and temperature stability rate via a serial USB port. All the other parameters are calculated and shown on included PC software
