2. Safety
DANGER!
Danger of death caused by electric current
Upon contact with live parts, there is a direct danger of death.
■
Electrical instruments may only be installed and mounted by skilled electrical personnel.
■
Operation using a defective power supply unit (e.g. short circuit from the
mains voltage to the output voltage) may result in life-threatening voltages
on the instrument!
WARNING!
Residual media in dismounted instruments may result in a risk to people, the
environment and the system. Take sucient precautionary measures.
Do not use this instrument in safety or Emergency Stop devices. Incorrect use
of the instrument can result in injury.
Should a failure occur, aggressive media with extremely high temperature and
under high pressure or vacuum may be present at the instrument.

4. Design and function
4. Design and function
4.1 Description
Principle of operation
This instrument is designed to detect limit levels of
liquids. For this purpose the sensor is equipped with a
V-shaped glass-tip. The model is also ideally suited for
level control, particularly in applications requiring high
precision. The measurement principle is independent of
the colour, refractive index, density, conductance and
dielectric constant of the liquid.
Integrated electronics include limit sensing and selfcalibration. The output is an open-collector pnp-transistor.
Gas
Liquid
4.2 Instrument design
The sensor is a one-piece device consisting of a mechanical connection which depends
on the type of sensor, and integrated electronics built into a stainless steel housing. The
measuring length, ML, to the sealing face is always 24 mm.

Keep the packaging as it will provide optimum protection during transport (e.g. change in
installation site, sending for repair).
5.3 Storage
Permissible conditions at the place of storage:
■
Storage temperature: -25 ... +70 °C
■
Humidity: 35 ... 85 % relative humidity (no condensation)

■
Proximity to hot objects
■
Mechanical vibration, mechanical shock (putting it down hard)
■
Soot, vapour, dust and corrosive gases
■
Potentially explosive environments, ammable atmospheres
Store the instrument in its original packaging in a location that fullls the conditions listed
above. If the original packaging is not available, package and store the instrument as
described below:
1. Wrap the instrument in an antistatic plastic lm.
2. Place the instrument, along with shock-absorbent material, in the packaging.
3. If stored for a prolonged period of time (more than 30 days), place a bag, containing a
desiccant, inside the packaging.
