4.6.5 DSC74C Two-Pressure Sampling Cell with Coil
The DSC74C with an outlet coil is designed for the most critical measurements at atmospheric
pressure. In the DSC74C, the coil is connected to the sampling cell outlet to protect the sensor
from ambient humidity disturbing the measurement. The coil can also be used as a cooling coil
for sampling from high temperature processes.
DSC74C parts are:
• Sampling cell, thread G3/8"
• Connection part with a needle valve and an integrated leak screw
• Reducing nipple (thread adapter), G3/8" - G1/2"
• Reducing adapter (thread adapter), G3/8" - G1/4"
• Diffusion coil (for measurements in atmospheric pressure)
