DSC74B Two-Pressure Sampling Cell

The DSC74B and DSC74C sampling cells are enhanced versions of the

DSC74. The body is designed in a way that it is possible to measure at

both system pressure and atmospheric pressure.

The DSC74B limits the flow rate with a fixed leak screw. The flow is

optimized for pressures 3 ... 10 barg. The fixed leak screw eliminates the

risk of opening the leak screw fully by accident and this way emptying a

gas vessel. The maximum flow can be increased, if needed, by removing

the leak screw and adjusting the flow manually with the valve. Harmful

gases can be recovered by connecting a collection system at the outlet

(not available from Vaisala).
