Linear transducer uses hall-effect technology

March 5, 2012

Model ELA linear transducer uses Hall Effect technology and mounts externally to mobile hydraulic cylinders. They can be used in double-ended cylinders, steering and long-stroke cylinders where gun drilling had previously been cost-prohibitive. They are easily filed replaceable and operate in temperatures from –40° to 105°C. Output ranges include voltage, current, PWM and CanBus. They offer stroke lengths up to 33 ft and resolution from 0.1 to 10 mm.

The brain of the linear transducer is a microprocessor, which controls and receives signals to a surface-mounted Hall effect microcircuits, all of which are mounted to a printed ciruit board. The completed PCB, containing the Hall effect chips and microprocessor are then inserted into a stainless steel or aluminum housing depending upon the user’s application. A magnet, which is supplied with every linear transducer, causes a voltage drop when it passes over the Hall-effect chip. The microprocessor reads the position of the magnet and correlates the voltage drop to a proportional voltage, current, PWM or CANBUS output.

Transducers can be designed up to 54 ft in length, for use 20,000 ft below the surface of the ocean, for hazardous environments.
