First pressure transmitter for mobile hydraulic applications which fulfills new safety standards.

MHS-1 is the first pressure transmitter launched on the market by WIKA which fulfills already now the new EC Machinery Directive that will come into effect soon. It was especially developed for safety-critical mobile hydraulic applications.

All over the world, there is a trend to increase the safety standards for the protection of human beings and the environment. This is also applicable for the mobile hydraulics sector. For this reason, the new EC Machinery Directive (2006/42/EC) - and together with this directive, the safety standards EN ISO 13849-1 (Performance Level, PL) and IEC 61508 (Safety Integrity Level, SIL2) - will become effective at the end of this year.

In accordance with these new standards, WIKA has developed a special pressure transmitter for load monitoring, brake monitoring and drive control to be used in commercial vehicles. Essential product features are a redundant measurement of pressure and signal processing as well as two output signals working independently of each other (4 … 20 mA, 2-channel) in a single instrument.

Therefore, the MHS-1 has extraordinarily space-saving dimensions and the installation can be done in a shorter time compared to the use of two pressure transmitters. Moreover, a higher process reliability can be reached thanks to the plausibility monitoring of both output signals.
