Precautions
User's Responsibility for Safety:
•
wide range of process sensors and technologies. While each
of these technologies are designed to operate in a wide
variety of applications, it is the user's responsibility to select a
technology that is appropriate for the application, to install it
properly, to perform tests of the installed system, and to
maintain all components. The failure to do so could result in
property damage or serious injury.
Wiring and Electrical:
•
operated device, only properly trained personnel should install
and maintain this product. Be sure that the power supplied to
the unit is appropriate for the electronics version supplied.

Installation:
1. Mount the transmitter so that the sensor port will not
become clogged with sediment or debris that could
hamper the sensing ability.
2. Although the transmitter is highly vibration resistant, it is
always good practice to mount the device appropriately to
minimize any potentially damaging shock and vibration.
3. Apply PTFE tape, or other appropriate thread sealant to
the NPT pressure fitting thread before installation. Tighten
the device using the 7/8” Hex next to the pressure
connection. DO NOT USE A PIPE WRENCH ON THE
TRANSMITTER HOUSING!
