Resistive level sensor

liquidanalogstainless steel

Auxitrol Weston has become a leader in sensors for measuring level in engine lube oil tanks and has delivered parts for more than 15 years and achieved > 20 million flight hours including use on recent engine programmes. The sensor operating principle is based on a resistive/potentiometric technology with the design as a network of reed switches and resistors activated by a magnetic float moving along an inner tube. This assembly is integrated in an external tube which plays the role of both a liquid movement damper and mechanical structure. Lube oil temperature measurement can also be implemented in the same device depending upon the application. Low oil level measurement is possible using a platinum RTD. Features Linear resistance/voltage output Current or voltage supply Vibration capability up to 50g across the standard bandwidth Benefits Full hermetic stainless steel design
