Two new ranges of fully programmable, digital panel indicators from Penny and Giles Controls Ltd - offer high performance features at a very competitive price.
To provide high system accuracy the AF111 and AF145 LVDTs have been designed primarily for use in the "difference over sum" (or ratiometric) configuration, where the output is not affected by temperature and supply current changes.
However, they can also be used in the differential output configuration more commonly used by other LVDT manufacturers.
A choice of mounting styles is available.
The AF111 has a threaded, unguided core assembly with the transducer body suited to clamp mounting.
The AF145 has self-aligning rod end bearings with an outer sliding sleeve, which provides an extremely rigid configuration that is resistant to vibration, mechanical shock and hostile environments.
Both models have a very small transducer "Body Length to Stroke" ratio (Penny & Giles claim it is better than any other LVDT available) as well as being smaller than comparable stroke linear potentiometers.
Models are available with strokes from 5mm up to 150mm and can be supplied from stock for immediate delivery.They are manufactured from 300 series stainless steel with welded and vacuum brazed joints to provide excellent corrosion resistance.
A new signal conditioning module (SCM100) has been developed for the AF111 and AF145 LVDTs, to provide the optimum performance measurement system.
The signal conditioning module will operate from a supply of 18 to 30Vdc or +/-15Vdc, and will provide an output voltage of 0-5Vdc, 0-10Vdc or +/-10Vdc.
Additionally, the option of a 4-20mA output is also available.
The SCM100 is supplied in a DIN rail format enclosure, and can be mounted up to 90 metres from the transducer, whilst being able to drive up to 300 metres of cable.
Used together, the Penny & Giles AF LVDT and Signal Conditioning Module, are as simple to use as a linear potentiometer, yet with all the LVDTs advantages of extreme ruggedness, low friction, infinite resolution, high temperature operation and long service life.
