3.2 Intended use
The model MH-4 is a pressure sensor that is used for pressure measurement in mobile working machines. The
pressure sensor may only be used in such applications as are within its technical performance limits, in particular with
regard to its material resistance limit and permissible temperature and pressure limits.
It is the sole responsibility of the manufacturer or operator of a machine or plant to ensure the suitability of the pressure
sensor, and its media resistance, within the application through proper choice of materials and maintenance cycles.
For performance limits, see chapter 8 "Specifications".
The model MH-4 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 GHS1) which are
mainly used for cooling, lubrication, cleaning or power transmission in industrial machines.
The mounting, dismounting, installation, parameterisation and maintenance of the pressure sensor in industrial
environments absolutely requires suitably skilled personnel in accordance with chapter 3.4 "Personnel qualification".
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.
