3 Qualified Personnel

All manuals and user guides at all-guides.com
are persons familiar with the insallation, assembly, commisioning and operation of the product and who have the
appropriate qualifications for their activities such as:
► training or instruction or authorization to operate and maintain devices/ systems according to the standard of safety
technology for elecrical circuits, high pressures and corrosive as well as hazardous media.
► training or instruction according to the standards of safety engineering in the care and use of suitable safety equipment.
Only trained qualified personnel shall execute this work.
Modules which are sensitive to electrostatic charge may be destroyed by voltages which are far below the human level of
perception. These voltages occur already when you touch a component or electrical connections of a module without first
discharging yourself electrostatically. The damage incurred by a module as a result of an overvoltage is not usually imme-
diately perceptible but only becomes noticeable after a long time in operation. Therefore, a suitable equipotential bonding
must be guaranteed when repairing the device.

4 Construction
The level sensor consists of a ceramic measuring cell (relative pressure) with an amplified electronic and is adjusted in the
requested pressure range. The sensor, the electronic and the connection cable are hermetically encapsulated in a stainless
steel case. The measuring diaphragm is protected from outside influences by a protection cover. A venting pipe is included
in the connection cable for the pressure compensation. The sensor, the electronic and the connection cable are placed in a
hermetic encapsulated small case.
The wide temperature range of the level sensor is compensated.
5 Application
The pressure level transmitter is used for hydrostatic measurement of liquid levels, e.g. in water supply, ship installations, in
the oil and gas industry etc.
CAUTION
Consider the chemical resistance of sensor, case, O-ring and connection cable with the media.
