NSTALLATION
HT7S Series transmitter is available in wall
mounting, duct mounting and flame proof duct
mounting. Light weight wall anchors and mounting
screws are included for wall mounting and a duct
mounting kit is also available for duct mount
models.
1. Wall Mount
With mounting Plates (Provided) attach the wall
assembly plate to the wall with two screws.
2. Duct Mount and Flame Proof Duct Mounting
To install these device, loosen up the LNKey screw
available on Flange so that Flange moves easily on
Duct Pipe. Insert the Duct probe in Duct hole at
desired depth and then tighten up the LNKey screw
on Flange. After this step fix the Flange on Ducting.
Mechanical Installation
Relative humidity is extremely dependent on
temperature. Proper measurement of relative
humidity requires that the probe and its sensors be
at exactly the temperature of the environment to be
measured.
Because of this, the location where you choose to
install the probe can have a significant effect on the
performance of the instrument.
