PR-36XW / PR-46X – KELLER hydrostatic fuel level transmitters

KELLER PR-36XW and PR-46X hydrostatic transmitters are professional solutions engineered for precise, continuous fuel level monitoring in rail vehicle fuel tanks. Installed directly inside the fuel tank, they eliminate measurement errors and guarantee maximum signal stability under demanding railway operating conditions.

The devices integrate seamlessly with the ASP3000 central telematics module, delivering real-time fuel data directly to server systems.

Why choose KELLER PR-36XW and PR-46X transmitters?

High-precision measurement: hydrostatic level detection provides repeatable accuracy regardless of vehicle operational dynamics.
Comprehensive consumption analytics: tracking level shifts, automated refueling detection, and average fuel consumption calculation (per 100 km and 1,000 km).
Flexible installation options: multiple probe lengths allow an ideal fit for varying tank heights across different vehicle series.
Resource protection: immediate detection of unrecorded fuel drops and complete auditing of refueling processes.

This solution sets high safety and quality benchmarks in the railway sector. It holds compliance certificates for EN 50155 (railway electronic equipment on rolling stock) and EN 45545-2 (fire safety).

Additionally, data transmission via the ASP3000 telematics module adheres strictly to the cybersecurity provisions of the Cyber Resilience Act (CRA).

Benefits:

complete, real-time fuel level visibility across the entire rolling stock fleet
error-free refueling control and rapid detection of unauthorized fuel removal
operational cost optimization and precise fuel management reporting
robust mechanical and environmental resistance designed for harsh railway conditions
tailored fit for fuel tanks with diverse geometries and depths
compliance with EN 50155, EN 45545-2, and Cyber Resilience Act (CRA) guidelines
