3. Safety
The model PSD-4-ECO has been developed for the pressure measurement of non-hazardous fluids, liquids and gases
(classification in accordance with Directive 2014/68/EU Article 13, Regulation (EC) No. 1272/2008, or GHS 1) ) which
are mainly used for cooling, lubrication, cleaning or power transmission in industrial machines.
WARNING!
Physical injuries and damage to property and the environment through exceeding the perfor-
mance limits
Exceeding the performance limits can destroy the instrument and lead to danger in the end-use
application.
▶
Only use the instrument in applications that lie within its technical performance limits. → For
performance limits, such as derating (maximum current consumption at a corresponding medium
temperature), see chapter 9 “Specifications”
▶
Any permanent operation in the overload range is not permitted. Above the highest operating
pressure permitted, up to the overload limit, the pressure sensor is operating outside its specifica-
tion. The overload range is intended to prevent damage to the pressure sensor, as part of a pressure
vessel system, during the pressure containment test.
▶
The overload limit must never be exceeded, even when failures occur in the end-use application.
Loads above the overload limit can cause irreversible damage, which can lead, for example, to
permanent measuring errors.
▶
The manufacturer or operator of the machine or plant in which the product is used must ensure the
compatibility of the materials of the wetted parts with the medium used.
▶
The pressure switch should not be used with abrasive or unstable fluids, in particular not with
hydrogen.
Special versions for oil and grease-free applications, as well as for use with oxygen (dangerous fluid according to
Directive 2014/68/EU Article 13, Regulation (EC) No. 1272/2008, or GHS 1) ), are available on request.
1) Globally Harmonized System of Classification, Labelling and Packaging of Chemicals
The (dis-)mounting, installation, parameterisation and maintenance of the model PSD-4 ECO in industrial
environments absolutely requires suitably skilled personnel in accordance with chapter 3.3. “Personnel qualification”.
