Pressure and continuous level measurement

Competitive pressure sensor for railway applications

• Tested according EN 50155
• High dielectric strength of 1 kV AC exceeding the standard according EN 50155
• High accuracy over a wide temperature range (-40 … 125 °C) due to active compensated temperature compensation
• Extended EMC immunity compared to EN 50121-3-2
• Traceability according GS1 standard
• Designed for a wide range of railway applications as e.g. pantograph pressure control, coolant recirculating pumps and pneumatic and hydraulic brake systems
• Frontflush pressure connection available for requirements of water applicatons as e.g. fluid management, water pumps, level monitoring, lavatory equipment and high viscosity media
