Personal injury hazard. Removal of a sensor from a pressurized vessel can be dangerous. Installation and
removal of these sensors should be done by individuals trained in proper high pressure and temperature
installation. Always use industry approved hardware and safety procedures when dealing with high pressure
and/or temperature fluid transport systems.
Refer to Figure 4 for installation of the sensor in different applications. The sensor must be calibrated
before use. Refer to Calibrate the sensor on page 20.
Make sure that the routing of the sensor cable prevents exposure to high electromagnetic fields (e.g.,
transmitters, motors and switching equipment). Exposure to these fields can cause inaccurate
results.
