Model MH-3 OEM Pressure Transmitter
Brand: WIKA Alexander Wiegand SE & Co. KG
Durable and Robust Shock and vibration resistance, resistance to pressure spikes from the WIKA Cavitation Dampening system (CDS), and an ingress protection of up to IP 69K make the model MH-3 pressure transmitter especially qualified for the harsh operating conditions in mobile hydraulics. Even extreme temperature shocks do not affect its performance.
The case is made of a highly resistant fiberglass reinforced thermoplastic (PBT). This material is successfully used within the automotive industry.
A metallic shield inside the instrument provides excellent EMC characteristics in accordance with EN 61326, thus ensuring reliable operation, even under high exposures of up to 100 V/m.
The hermetically-welded thin-film measuring cell ensures long-term leak-tightness, without the need for additional sealing materials. Especially in applications with high dynamic load cycles, the thin-film measuring cell features high long-term stability and load-cycling resistance.
State-of-the-Art Manufacturing Our manufacturing concept is optimally designed for the production of OEM needs. Also customer-specific modifications of the instruments are possible.
Diagnostic Function As a measuring instrument of the latest generation, the MH-3 features a diagnostic function. By means of the output signal, fault conditions can be detected and evaluated via software. Thus it is possible to differentiate between permanent and temporary faults.
