INSTALLATION
2.3 Transmitter Mounting
Take care to prevent any contamination of the sensor before installation (handle the
transmitter by the main body only, avoiding contact with the fi lter disc).
The SF52 can be mounted either into a fl ow-through sensor sampling block (optional)
or directly into a pipe or duct. It can be operated at pressures of up to 2 MPa (20 barg
/ 290 psig) when fi tted with the bonded seal provided.
The recommended gas fl ow rate, when mounted in the optional sampling block, is 1 to
5 Nl/min (2.1 to 10.6 scfh). However, for direct insertion applications, gas fl ow can be
from static to 10 m/sec (32.8 fps).
NOTE: Pass the seal over the mounting thread and assemble into the sampling
location, by hand, using the wrench fl ats only.
When installed, fully tighten using a wrench until the seal is fully compressed and to the
following torque settings:
• G ½” BSP 56 Nm (41.3 ft-lbs)
• ½” NPT 56 Nm (41.3 ft-lbs)
