OEM pressure transmitter MH-3
for mobile working machines
Developed and tested for mobile
working machines
The MH-3 pressure transmitter has been speciﬁcally developed for mobile working machines. Intensive ﬁeld tests as well
as comprehensive internal testing ensure that the MH-3 is up
to the harsh demands of mobile working machines.
A large part of the testing is carried out in WIKA‘s own laboratories. In this way, individual customer requirements can be
taken into account.
Among the tests are:
Environmental inﬂuences
EMC inﬂuences
Shock/vibration
Pressure spikes
IP protection

The next step
Based on market experience with mobile working machines,
the MH-2 pressure transmitter has been enhanced. The existing look and feel of the proven forerunner has been retained.
The MH-3 has also had a diagnostic function added. In addition, signal clamping (limiting the signal value to a customer
settable value) is also available.

Modern manufacturing
The in-house production of the sensor, the population of the
printed circuit board and the complete assembly on a fully automatic production line at WIKA enable continuous traceability of each individual manufactured unit, down to an individual
component level.
