Vaisala DSC74SP

Sample Cell with Quick-connector and lead screw

The DSC74 has been designed especially for compressed air lines. The sampling cell contains an adjustable leak screw that allows keeping up the pipeline pressure at the sensor. The leak screw should be ½ turn open. This can be verified by first closing the leak screw, then turning ½ turn to open it. Then the air coming out will make a hardly audible little fizz and it can be lightly felt when putting a hand in front of the air stream.

The DSC74 comes with a quick connector that fits to the industry standard compressed air line connectors. This allows for easy installation and detachment of the dewpoint transmitter without having to shut down the process.

Alternative ways to connect are through the two different thread adapters (G⅜” to G½” and G⅜” to G¼” ISO) that are supplied with each DSC74 unit.

Compatible with the DM70, DMT132, DMT142, DMT143, DMT152, DMT242, DPT146, and DMT347* transmitters.* with ISO½” Swagelok connector
