PWM offers low cost digital signalling

PWM offers low cost digital signalling Penny & Giles has developed a pulse-width modulation (PWM) option for its ICT range of contactless in-cylinder linear transducers. Launched last year, the rugged and reliable ICT range was designed for hostile conditions inside mobile and static hydro-pneumatic actuators. The new option provides further assurance for OEMs as the digital signal of the PWM is more robust and less vulnerable to noise than analogue voltage signals. Penny + Giles' ICT transducers come with a separate electronics package, EICT. This can be located up to 10m away from the transducer protecting it from the harsh environments associated with heavy-duty applications such as steering position actuators and hydro-pneumatic suspension systems. Currently, the EICT provides analogue position feedback proportional to the cylinder rod position for actuator strokes up to 2000mm. The PWM option produces a TTL-level compatible signal which has a duty cycle proportional to transducer displacement. This can be converted easily to a digital value by most microcontrollers without the necessity for expensive high-resolution A/D converters. Four different output frequencies can be selected, 100Hz, 130Hz, 310Hz and 1000Hz, allowing users to choose the best compromise between digital resolution and acquisition speed for their particular system.
