The model MH-4 is a powerful, reliable and extremely resilient pressure sensor for mobile working machines. Even under demanding conditions, the maintenance-free sensor delivers constant, precise measured data and ensures high operational safety. Thus it is the ideal choice for OEM use.

Developed for the specific requirements in mobile working machines
The model MH-4 meets high demands and measures with high precision at temperatures between -40 and +125 °C [-40 ... +257 °F]. With its up to 3 times overpressure limit, the sensor withstands hydraulic pressure spikes – and is optionally available with a restrictor. Thanks to metallic shielding, the model MH-4 works interference-free at field strengths of up to 100 V/m. In addition, vibrations up to 40 g and shocks up to 100 g have no influence on the measurement quality.

Highest reliability over the entire life cycle
Whether dust, humidity, heat or mechanical stress: The model MH-4 pressure sensor is optimised for mobile use, particularly safe in operation and thus continuously dependable. The maintenance-free instrument design ensures a particularly low total cost of ownership. Even after more than 100 million load cycles, the long-term drift is still less than 0.1 % FS.
