9 DESCRIPTION
The PMA 20 is a reliable and easy-to-operate instrument. It is built into a compact wall mounting
housing. The transducer unit maintains a constant operating temperature of 50 °C and a flashing
LED on the control panel indicates the proper operating temperature of the analyser. The four
measuring ranges are displayed on the analogue meter with 30/ 100% scale. Two output signals
are available. Sample gas connections as well as connectors for incoming power supply and out-
put signals are located inside the terminal box of the housing. The sample gas enters the analys-
er via an external protective fine-filter. The required flow rate can be adjusted at the flowmeter
with needle valve, mounted on the front panel upstream the M&C measuring cell. The internal
tubing is made of FPM and PP.
Option: ”TÜV certificate” or chlorine resistant version.
