Hydraulic Cylinder Displacement Transducer System

The DC HydraStar® is a variable inductance linear position sensor specifically designed for installation into hydraulic and pneumatic cylinders and actuators. The DC HydraStar® incorporates a compact, environmentally protected signal processor which requires only DC power to operate and gives outputs of 0 to 10V DC, ±10V DC or 4-20mA.

The DC HydraStar® transducer consists of a sensor body which is mounted to the end cap of the cylinder. The aluminum core includes a mounting collar which mounts to the piston rod. In operation, the HydraStar sensor body senses the position of the movable core and gives an output directly proportional to the piston rod position. The transducer includes a 10 foot (3M) cable for connection to the signal processor.

The DC HydraStar® Signal processor is packaged in an aluminum enclosure rated NEMA 4 (IP 65). This processor box contains all circuitry required by the HydraStar and includes a mating connector for excitation input and signal output.A comprehensive instruction manual is provided with each DC HydraStar® to provide guidance in installation into the cylinder as well as system calibration.
