Page 16: Product Description
Product description 3 Product description 3.1 Function 3.1.1 Gauge mode of operation The measurement currents of the measurement systems (Bayard-Alpert and Pirani) are converted into a measured value-dependent frequency in a current/frequency converter. A micro-controller generates a digital value from this frequency signal as a measure for the total pressure measured. This value is available again as an analog measurement signal from 0 to 10.2 V at the output (pin 2/3), and the valid pressure measurement range goes from 0.774 V to 10.0 V (atmospheric pressure). -
