Pressure Transmitter in Mobile Hydraulics

10 Mobile Hydraulics
9 Mobile Hydraulics
OEM Pressure

The pressure transducers of this series are specially designed and developed for Mobile applications and Off-Road Vehicles. Development of EMI and environmental robustness are made for these transducers. These transducers are able to be fitted with a “load dump” module. This module provides protection to load dump pulse according to ISO 7637.

In addition, snubbers can be attached to these transducers. These snubbers are intended to reduce pressure spikes in hydraulic applications. Snubbers are available with opening diameters of 0.6mm (0.0236 inch) or 0.3mm (0.0118 inch). The pressure port and the sensing element are made of stainless steel and fully electrobeam welded in a special process.

  • Fully welded construction
  • High chemical/media compatibility by the use of stainless steel
  • High rate of pressure cycle withstand
SKU: SMO Category:

Due to its stainless steel membrane and to its semiconductor thin-film technology, the transducer has excellent properties regarding its long-term stability, medium compatibility and pressure peaks that suggest its advantageous use in most industrial applications. Also its robustness, even in very rugged ambient conditions in the field of mobile hydraulics, is guaranteed by its welded stainless steel housing. The EMC properties of this series permit its application also in sophisticated environments. Its ratiometric model has been successfully tested up to 300V/m.

Features:

  • Measuring ranges -1…0 bar & 0…5000 bar
  • Output signals 4-20 mA; 1-5 V; 0-10 V; 0.5-4.5 V ratiometric
  • Temperature range of media up to 150°C
  • Shock and vibration resistance > 1000 g shock, > 30 g vibration
  • Protection class IP67 (special version up to IP69K)
  • Compact and rugged model in stainless steel
  • High flexibility for options thanks to modular design
  • Highly reliable
