with the product.
▶Keep this documentation in a location where it is accessible to all
users at all times.
▶Always pass the product together with the required documentation
to third parties.
2.2 Intended use
The product is an electronic component. These pressure sensors
comply with the Pressure Equipment Directive and are designed and
manufactured for group 2 uids in according with sound engineering
practice. You may use the product as follows:
• For acquiring the system pressure in hydraulic and pneumatic
systems.
• While adhering to the operating and ambient conditions and
specied performance limits according to the data sheet.
• In the original condition, without damage.
• Only in applications for which they are suitable without any
restrictions.
• Only within the pressure limits provided in the operating range.
The product is intended exclusively for professional use and not for
private usage.
Operation according to the intended use also implies that you have
read and understood this documentation completely, especially
chapter 2 “Safety instructions“.
2.3 Improper use
Any use other than described in the section “Intended use” is
considered as improper and is therefore not permitted.
