P26 Instruction Manual

Safety precautions
2.1 Appropriate use
The P26 is used to measure pressure, volumetric flow, mass flow and flow rate.
Always observe the operating requirements
– particularly the permissible supply voltage –
indicated on the rating plate and in the “Technical data” section of this manual.
The instrument may only be handled as indicated in this manual. Modifications to the
instrument are prohibited. The manufacturer is not liable for damages caused by improper use
or failure to follow these instructions. Violations of this type render all warranty claims null and
void.
2.2 Shipping, assembly, electrical connections and start-up
Do not close the pressure inlets during shipping. Changes in barometric pressure may
damage devices with low measuring ranges.
Assembly and the electrical connections should only be handled by professionals. They should
be given proper training and be authorised by the operator of the facility.
Although the P26 pressure transducer is highly robust, it is nevertheless a precision instrument
and should be handled with care. Avoid mounting the P26 in the direct vicinity of any sources
of heat or radiation. Ideally, the instrument should be mounted vertically on a wall not subject
to vibration.
The instrument may only be operated by appropriately trained individuals who have been
authorized by the operator of the facility.
Do not carry out a function test with compressed or breathable air. This would damage
instruments with low measuring ranges.
The pressure ports may only be connected and disconnected when the device is switched off.
Measurement errors may occur if the instrument is not kept protected from sunlight.
Specific safety precautions are given in individual sections of this manual.
