Lightweight, catch tank oil level sensor
- ACO approved for endurance motorsport
- Compact and lightweight
- Simple to install

Originally designed for the ACO Le Mans Racing Series, the oil catch tank sensor is based on Gill’s proven capacitive level sensor technology.
Because of the length of an endurance race, the ACO has to be confident the sensor will remain accurate, reliable and repeatable over the course of the race, providing a continuous analogue output relative to the level of oil within the catch tank. This is important as the sensor was introduced to prevent overfilling which leads to spillage and unsafe racing.
Weighing just 90 grams with two 3mm diameter mounting holes for simple installation, the sensor builds on the success of the pit-tank level sensors installed in refuelling rigs for the Le Mans 24 Hours race.

CatchTank Oil Level Sensor - more details
Designed & Manufactured by Gill Sensors & Controls in the UK, the catch tank level sensor provides precision level measurement of oil for motorsport applications where weight and space are at a premium.
Gill catch tank sensor provides proven reliability in demanding motorsport environments delivered by lightweight, solid-state capacitive level sensing technology.
This is a component part to be incorporated into a larger system and as such the catch tank level sensor is not a finished unit intended for an end-user. Therefore the product is not classed as apparatus within 2014/30/EU.
Every sensor is factory calibrated with temperature compensation to provide market leading accuracy as well as quick and easy setup.
A tank profiling feature allows the level sensor to provide accurate tank volume output results even in irregular tank shapes.
Environmental protection to IP68.
Gill capacitive level sensors have no moving parts and as a result are extremely reliable and accurate, requiring minimum maintenance.

Liquid Level Sensor Accessories
Gill liquid level sensors are supported by standard accessories to assist with specific installation requirements.

USB to RS232 adaptor
The USB to RS232 cable adaptor allows connection of a Gill LevelPro LevelLite or CatchTank liquid level sensor to a computer where the sensor can be quickly configured using GSlevel software. (only the FTDI USB-RS232-WE-1800-BT_5.0 is fully supported – other converters may not be compatible).

Liquid Level Display
Gill Liquid Level Display can be programmed to ‘map’ the tank shape to display true volume rather than simply liquid height.
Provides a real-time quick visual reference and an accurate numerical reading (using 29 bright LEDs and a seven segment panel) with light-sensitive auto-dimming for night use.
Fully programmable with a low level alarm.
Compact and lightweight for easy installation on dashboards and instrument panels (shallow 6mm depth aluminium bezel).
GSlevel Software

Overview
GSlevel software is designed for easy level sensor customisation and is free to download. The software allows control over output settings, minimum and maximum levels and alarm switch levels for ultimate adjustability.
GSlevel also allows the user to achieve a volumetric output using its tank profiling feature. Users can reconfigure the sensor using the simple configuration wizard or by uploading a CSV file to profile a cross-section of the data to gain a volumetric output.
Compatible products: LevelPro, LevelLite, LevelSlick and CatchTank level sensor.
Compatible operating systems: Windows® 7 or later
