Customization and R&D

TCD3000 SI

The compact and robust TCD3000 screw-in transmitter is ideal for the precise, fast and sensitive measurement of (quasi) binary gas mixtures. The measurement is based on the principle of thermal conductivity. This technology is ideal for measuring gases with very different thermal conductivities, such as H2 and air.

The TCD3000 Screw-in is designed for installation with a G½” thread for flush screw mounting. For installation, a wrench size (SW) of 36 and a torque of 100 Nm are required for direct installation in the process. Sealing is provided by an O-ring.
