Type FF-
1 Introduction
1.1 Intended use
A moisture detector is a device which signals moisture in the gas flow of a sample gas treatment system. Here the electrodes
separated by a gap are located inside the Gas flow.
The circuit devices Type FF analyse the moisture detector FF-3-N and FF-40. These devices allow the analysis of moisture ingress
in the sample gas detected by the moisture detector, and to trigger an alarm.
1.2 Types
