3.2 Intended use

The pressure sensor is used for measuring pressure. The measured pressure is output
as an electrical signal.
The pressure sensor model MH-3 is intended for use in mobile working machines.
The MH-3-HY pressure sensor for mobile hydrogen applications is typically used to
monitor tank pressure and the pressure after the reducing valve in hydrogen-powered
vehicles, especially industrial trucks, utility/municipal vehicles and buses. The exact
position of the sensor is therefore dependent upon the customer and application.
Only use the pressure sensor in applications that lie within its technical performance
limits (e.g. max. ambient temperature, material compatibility, ...).
→ For performance limits see chapter 9 "Specifications".
The instrument has been designed and built solely for the intended use described here,
and may only be used accordingly.
The manufacturer shall not be liable for claims of any type based on operation contrary
to the intended use.
Technical restrictions
Any permanent operation in the overload range is not permitted. Above the operating
■
pressure, up to the overload limit, the pressure sensor is operating outside its speci-
fication. The overload limit 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.
