SAFETY INSTRUCTIONS
1
1.4 Pressure equipment directive
A conformity assessment in accordance with pressure equipment directive has been carried out
for the devices described. Conformity is certified by applying the CE mark. The number of the
notified body is also stated.
The PED key describes the rating of the devices:
Example: PED/G1/III/H
G
1
III
H

The PED key identification can be found on the nameplate of the device (for details refer to
Nameplate
INFORMATION!
The stated pressures (PS) and temperatures (TS) only apply as refers to the pressure resistance
of the sensor body. As regards the functionality of the entire device, further restrictions of the
maximum temperature may need to be observed (e.g. ATEX approval). Devices rated below
category I due to their size, do not receive the CE mark in the scope of the PED. These devices
are subject to applicable sound engineering practice (SEP).
Residual risk
A risk analysis in accordance with the pressure equipment directive has been carried out for the
devices . The residual risk is described as follows:
• The devices are designed according to the valid and applicable rules and standards for static
operation and their pressure resistance is calculated for the declared maximum pressure
and temperature (no calculation for cyclical change).
• Responsibility for the use of the measuring devices with regard to corrosion resistance of the
used materials against the measured fluid lies solely with the operator.
• Don't use abrasive and high viscous media.
• Avoid pulsation and cavitation.
• The maximum allowable ambient temperatures are depending on the device equipment and
declared in the technical data.
• The draining of the device will be performed in the same way as the connected pipeline.
• Protect devices from vibration and high-frequency oscillation.
• Implement appropriate measures to counteract external fire hazards
