Sampling Accessories
DMT242SC Sampling Cell
The DMT242SC is a basic sampling cell with only the main sampling
cell body. The inlet and outlet are female threaded sample connectors
(inlet G3/8", outlet G1/4" ISO). Refer to Figure 16 on page 26.
The DMT242SC is suitable for users requiring only a sampling cell to fit
the transmitter into and doing further assembly (piping into inlet &
outlet, valves, possible flow meter) by themselves.
DMT242SC2 Sampling Cell with
Swagelok Connectors
The DMT242SC2 is similar to DMT242SC, but connections are made
easy. The sampling cell includes welded swagelok connectors at both the
inlet and outlet that fit directly to 1/4" tubing.
To fit 6 mm tubing to the connectors, an adapter such as Swagelok®
Reducer SS-6M0-R-4 (not supplied by Vaisala) can be used.
DMT242SC2 is the suitable choice in, for example, plastics drying
systems, where the measurement is made by tapping off the dryer system
and bringing a small air stream to the sensor. The swagelok connectors of
DMT242SC2 easily connect to a cooling coil or tubing providing the
essential function of cooling the dry air to ambient temperature before it
reaches the sensor.
