3050-AP Moisture Analyzer
gas streams, is a function of the moisture content of the sample gas. Thus, the
moisture concentration of the sample gas is determined from this frequency
difference. The calibration data, which relates the moisture concentration of
the gas stream to the measured frequency difference, are stored in an EE-
PROM within the QCM sensor module.
Controller Communication
All analyzer functions are controlled by a microprocessor housed within the
smart sensor. Communication with the smart sensor is achieved through the
following connections:
• One analog input, 4 to 20 mA
• One analog output, 4 to 20 mA, isolated. Can be either loop powered or powered by
the analyzer.
• Three alarm contacts, (dry relay contacts)
• One RS-232 serial port
• One RS-485 serial port.
