Specifications

Rugged  design
The extremely high resistance to shock, vibration and pressure peaks (CDS-system), combined with degrees of protect on better than IP 68, offered by mode MH-1 make the  instrument particuarly suitable for the rough operating conditions of mobile hydraulic applications.

Pressure ranges from 0 ... 60 bar up to 0 ... 600 bar are available to meet all standard mobile hydraulic applications.

Proven thin film sensors
The hermetically welded thin film measuring cell eliminates the need for additional sealing materials and ensures long term leak tightness.

The thin film measuring cell is made of high quality stainless steel using sputtering technology to offer long term stability especially in applications subjected to frequent load changes.

The sensor is recessed into the pressure connection on to offer additional protection against oil loss should the sensor become damaged by misuse on site (for example, when the sensors is destroyed by turning crane loads).

The instrument design adapted to mobile applications permits shock  loads up to 500 g and vibrations up to 20 g.

Very good EMC characteristics complying with EN 61 326 as well as DIN 40 839 ensure reliable function even under difficult EMC conditions. Additional protection against load dump up to 200 V is integrated.

High ingress  protection
Even extreme thermal shocks have no influence on the operational safety. This instrument offers a wide range of ingress protection classes particularly for mobile applications. In addition to a locking plug M 12x1 with ingress protection IP 67, the pressure transmitters can be shipped with a plug DIN EN 175301-803 shape C, with IP 65. Cable versions are also available with ingress protection classes up to IP 69K (steam jet protection) or premounted plugs to customer specifications.
