Oil Level switch design for UK commercial trains

May 14, 2014

gill-rd-application-story-alstom.jpgAlstom, a UK manufacturer of flagship passenger rail rolling stock, came to us needing a level switch solution to measure oil in their Pendolino 390 class passenger trains.

The Challenge

Alstom required a non-contact switch which would fit into the engine that would not jam or break, unlike the previously used float switches. Due to the consumer end-use of the application, reliability and durability were paramount to ensure that the solution would support the flagship trains and its service.

The Result

Gill R&D conducted research to utilise its existing capacitive technology, resulting in a superior replacement of the customer's previous sensor.

We developed technical drawings, CAD models and environmental testing include EMC, vibration and humidity testing, to ensure the solutions were suitable for use across the fleet and would meet the rail standard tests.

A reliable, solid-state prototype was manufactured using in-house facilities, providing Alstom with a highly reliable level switch for installation across their fleet of commercial trains

Phases of working with the customer

  • Design specification developed with Alstom
  • Internal review of our technology for form and fit
  • CAD model and technical drawing produced
  • Proposed specification provided, with suite of suggested test programmes to BS standards
  • Quotation with and without test programme provided
  • Design and manufacture of prototypes
  • Prototype redevelopment
  • Product spec units built for testing
  • Fully approved unit provided
  • Production phase and delivery of units
