Position feedback for civil engineering hydraulics
Constantly expanding infrastructure, means increasing use of hydraulics to position, move, and control, locks, gates, and even bridges. Heavy duty Micropulse linear position sensors provide accurate, reliable position feedback in these hydraulic systems.
Floating debris at the infeed end of hydroelectric power plants impairs the performance and efficiency of the plant. The worst-case scenario could result in costly downtime. Balluff BHS pressure-rated inductive sensors reliably detect the rake cleaner end positions and act as a safety and protection system for hydropower plants.
The requirements for a dam go much further than just opening and closing the gate. Fish ladders must be taken into account and the fully automatic control of the water level must be ensured. Balluff BSI inclination sensors reliably and precisely measure the intermediate position of the gate. The sensors with metal housing and a wide temperature tolerance range are specifically designed for use outdoors.
Balluff Micropulse ProCompact magnetostrictive linear position sensors are used in the hydraulic cylinders that control the opening and closing of the lock gates. The hermetically-sealed, IP69K-rated enclosure protects against environmental hazards, and ensures long-term, reliable performance.
Time is of the essence when raising and lowering movable drawbridges, as impact on traffic must be kept to a minimum. Our high-precision Micropulse magnetostrictive linear position sensors, which are integrated in the hydraulic cylinders, allow the bridge to raised and lowered as quickly as possible. Our pressure-rated inductive sensors reliably detect the end positions of the cylinder and position the bridge with precision.
When building bridges, special heavy-duty cylinders carry out horizontal feed and vertical lifting motions to move the bridge elements, which weigh several tons. The synchronous positioning with millimeter precision of bridge elements weighing several tons is undertaken by our BTL rod CD magnetostrictive linear position sensor, which is installed in the pressure range of heavy-duty and high-pressure cylinders.
