LMP1 Coolant Level Sensor

May 14, 2014

gill-rd-application-story-lmp1.jpgTo develop an engine coolant level sensor that would meet the accuracy and reliability requirements of Le Mans Prototype Class 1 endurance racing, whilst also satisfying the weight and mechanical demands of the installation.

The Challenge

Motorsport imposes extreme vibration and temperature values that require a sensor of exceptional mechanical durability whilst providing high accuracy, dependable measurement outputs.

Coupled with these needs, the device must have minimal weight, integrated electronics, within a compact and unique mounting flange configuration.

The Results

By using the solid-state, capacitive technology refined by Gill R&D, a compact, lightweight and mechanically dependable sensor was produced to integrate into the customers' installation. By consideration of a number of materials options, a balance of weight, corrosion protection and cost was achieved to satisfy customer need.

The sensor had a unique flange design to fulfil the mechanical constraints and was provided in a unique colour finish to assist in differentiation with the other level sensors used on the car.

Project results and benefits

  • Supply of custom coolant level sensor to specific mechanical constraints
  • Optimised weight and corrosion protection
  • Reliability under extreme temperature and vibration levels
  • High measurement accuracy performance
  • Non-standard colour finish
  • Electronics integrated into sensor housing
  • Supplied calibrated to specific customer liquid mixture

Phases of working with the customer

  • Requirements capture
  • Flange/mounting design to fit within the available space
  • Offered calculated product weights for Ti, St/ST & Al with pricing
  • Discussed corrosion resistance of Al with the coolant the customer used
  • Approval and verification of design and performance
  • Provided custom colour configuration
  • Produced 3 prototype sensors
  • Providing sensors for 2014 race season
