Penny & Giles • Contactless design - Inductive technology • Wear-free operation • Separate signal conditioning (EICT) o High performance driver circuit o Zero and span adjustment o Choice of enclosure designs The ICT050 Contactless In-Cylinder Linear Transducer has been specifically designed for smallbore, mobile and static hydro-pneumatic actuators. Designed primarily for the off-highway markets, the ICT050 linear transducer provides reliable, fit-and-forget position sensing of the cylinder rod in actuators with strokes up to 500mm, with a body diameter of only 5.4mm. It is a robust, non-contact transducer suitable for the harsh conditions of lifting and steering position applications and hydro-pneumatic active suspension systems. It works on an inductive coil principle, with virtually infinite resolution and is capable of withstanding temperatures down to -20°C and up to +200°C, with working pressures to 500Bar (7250psi). The EICT signal-conditioning module has been specifically designed to operate with the Penny and Giles range of SLT and ICT contactless linear position transducers. The module incorporates a high-performance circuit that drives the transducer and provides a choice of output signals with zero and span adjustment for simple user configuration. The module can be supplied in a choice of enclosures, with sealing to IP66 or IP68 protection.

The green wire is internally connected to the transducer case. Due to the construction of the transducer external moving parts, the green connection should not be used as a ground connection. The enclosure is not connected internally to ground, so it can be mounted on a chassis carrying a voltage potential other than 0Vdc Misconnection of the supply may cause permanent damage. Maximum recommended distance between transducer and signal conditioning module is 10m. Each transducer is supplied with a sensor calibration module card (SCMC), calibrated to match the electrical stroke length. The EICT...

If using a voltage module, connect the VM card by inserting connector into position on header JP2 of EICT/EICTM PCB. Do not insert CM or PWM cards at this stage. Connect a DMM set to measure voltage to the output (terminal 5) and GND (terminal 6) on the EICT/EICTM PCB. Move the transducer core to the fully 'Lo' position (See Step 4 and Fig. 2) and power up the EICT/EICTM. Adjust ZERO trim pot until the required output voltage is achieved on the DMM display (0.5Vdc if no VM card is fitted in JP2). For Dual Supply option, output over the full range, relative to ground ('GND' 0V) will appear on...

• EICT/EICTM must be disconnected from the transducer to carry out following check. • Using a DMM, set to the resistance range: • Measure between connections assigned to transducer 'yellow' and 'blue'. Value should lie between 400 and 1700. • Measure between connections assigned to transducer 'green' and 'yellow' and/or 'blue'. Value should be 'open circuit'. • Measure between connections assigned to 'green' and the transducer body. Value should be 'short circuit'. • 'Screen', if used - Connections assigned to 'screen' should be 'open circuit' to all the other electrical connections and transducer...
