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 brains of the linear transducer are the microprocessor which controls and receives signals to the surface mounted Hall Effect chips, all of which are mounted on a PCB. The completed PCB with all 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 understands the position of the Hall Effect chip and correlates the voltage drop to a proportional voltage, current, PWM or CANBUS outputs.
Transducers can be designed up to 54 ft in length, for use 20,000 ft below the surface of the ocean, for hazardous environments.
