Position and movement sensor solutions company Hamlin is launching its new range of noncontact automotive fuel level sensors at Electronica 2004 in Munich.
Position and movement sensor solutions company Hamlin is launching its new range of noncontact automotive fuel level sensors at Electronica 2004 in Munich.
Hamlin's new sensor will benefit vehicle manufacturers and fuel tank suppliers with its improved sensing accuracy and reduced warranty costs.
The component is of modular design with a standard body and an easy to customise float and float arm.
Accurate and reliable level sensing is achieved using an annular magnet and programmable Hall effect sensing element.
"Our new fuel level sensors use programmable Hall effect technology from Micronas", said Marcel Briers, Hamlin's Director of Global Sales and Marketing.
"This technology allows us to tailor the sensor to each new tank design without burdening our customers with custom tooling expense".
"It also enables us to supply a sensor that will measure accurately even when used in moulded tanks with irregular shapes where the level of fluid will change at a nonuniform rate".
The sensor uses noncontact technology and components parts, such as the sensing element and magnet, are either moulded or hermetically sealed into the device.
This means it is not susceptible to the typical causes of failure associated with current methods of fuel level sensing.
Although the sensor has been designed with the hostile environment of an automotive fuel tank in mind, the product is very well suited to other applications where low cost accurate and reliable fluid level measurement is required.
Visitors to the Electronica show will be able to see a demonstration of programmable level sensor solutions at Hamlin's stand as part of the company's active display exhibit.
Hamlin can be found in Hall 3, on Stand 206.
In 2003 Hamlin and Micronas signed a cooperation agreement under which Hamlin has special access to Micronas' expertise in the field of programmable Hall effect technology.
The two companies work very closely on numerous projects.
