medium to be measured is liquid. If there are water hammer effects in the system, it is
recommended to use a sensor complete with a hydraulic shock dampener.
To reduce the temperature acting on the isolation diaphragm when measuring vapor pressure, it
is recommended to use impulse tubes. The impulse tube must first be filled with water.
Attach the equipment in a safe configuration that prevents unwanted stress (vibration, physical
impact, shock, mechanical and thermal stresses). Do not install the equipment where it can be
damaged by a material that causes corrosion. Provide additional protection for the equipment if
it may be damaged in service.
When installing power supply and signal wiring, the possibility of condensate entering the sensor
cable entry should be avoided.
3.3 Connecting to a Pressure Source
When mounting the sensor, seal the mating surfaces. Failure to properly seal may affect
performance or calibration accuracy.
Male threaded pressure connectors must not be sealed or constrained against the face at the
base of the thread. The forward cone or flat face should always be used as indicated below.
Depth versions should not be used at hyperbaric pressures above 70
bar (1000
psi),
approximately 700
m (2300
ft) of water.
3.3.1 Media Compatibility
The media compatibility of the sensors is shown in Table
Note:
Fluid classification complies with European Regulation (EC) No 1272/2008. Statements
comply with European Pressure Equipment Directive 2014/68/EU.
