Gentech Sensors verify minimum oil level for safe engine start-up

Requirement:

The client , a construction and agricultural equipment manufacturer, wished to remove the risk of diesel engines being started with low oil levels. Typically the task of checking levels is carried out manually and is often neglected or forgotten. Ensuring minimum oil levels are safe prevents costly equipment failure and downtime. A sensor, positioned in a confined space in the engine, was required to interface with the engine management system to prevent start up when unsafe.

Design parameters:

• One level of switching required
• Located in the base plate
• Maximum diameter of insertion in the base plate of 16mm
• Limited space inside the engine
• Sensor to operate at +140°C to -40°C
• To operate in standard production oil
• The sensor is mounted at an angle into the engine

Solution:

A low oil sensor was custom designed - packaged in a Nylon 66 housing. The design allowed the sensor to fit into the base plate and a threaded connection made installation straight-forward. To accommodate the limited space the float was restricted to 16mm

Design outcome:

• Based around Gentech EVS Product Range technology
• Nylon 66 housing
• M18 X 1.5 thread connection
• Sealing gasket
• IP6K9K Connector
• Float under 16mm diameter
• Overall length 172mm
• Fitted with a Deutsch two pin connector
