| Also
available is the Deva 023 reader head pre-amp for use
with standard Brown & Sharpe reader heads commonly found
on MicroVal EM and MicroVal series machines. The Deva 023
performs the necessary signal conditioning required for use
with the Deva 018 to expand the use of Deva's motion and measurement
cards as a complete CMM retrofit solution for a variety of
machines from manufacturers such as Brown & Sharpe, Tesa
and DEA.
The Deva 023 has a 15 way 'D'-type
connector at one end, which is pin compatible with the existing
reader head and the other end of the module has a high-density
15 way 'D'-type connector that mates directly with the Deva
018. The module incorporates 4 trim pots which are used to
scale and offset the sine wave signals in the same way as
found on existing equipment. The trim pots may be linked out
if they are duplicated on the existing cable.
