November 17, 2006 - A new sensor of IBJ Technology from PVDF arrays for the measurement of the piston position with ultrasonic achieves high local dissolution, how it was unequalled for sensors on ultrasonic basis so far.
A PVDF foil (ultrasonic sensor array) lies full-laminar on the cylinder wall. The single sensors of the array are queried over multiplexers lively and. The patented evaluation procedure works without disturbing absorption influences and without temperature dependences. The measurement of longer procedure distances of the piston is possible by lining up of several sensor arrays. The expenditure of discrete elements is very small.
Economical end position switches with redundancy can be developed with a simple sensor array. Replacement past mechanical end position switch in hydraulic's applications. The structure height of the sensor amounts to only few millimeters. Additionally also the range of application for simple, economical hydraulic's applications within the range opens automotives. Priority applications: Controlling and regulation of any hydraulic cylinders, monitoring of energy storage (piston accumulator), end position monitoring of hydraulic conveyer systems, stabilizers in shipbuilding and offshore one, monitoring of construction machines, monitoring of hydraulic door clamps, control and monitoring of hydraulic components of wind-powered devices, plants for seawater desalination, additional assembly to existing hydraulic cylinders without interferences.
