I have a Vision Microsystem VMS 1000 engine-fuel
management system which has now been in service for ten years on my
fuel-injected 320. I'm more than satisfied with it's performance;
however, in spite of a 'by the book' installation of the fuel pressure
transducer, I've had three fail in the past ten years. JP Instruments (who purchased Vision
Microsystems several years ago) now wants an outrageous $400 for a replacement
transducer. They keep the manufacterer/model a secret in order to support their
price, but some research revealed it to be a Honeywell 'MediaMate' model
MM050PG1HA http://sensing.honeywell.com/index.cfm/ci_id/142358/la_id/1/document/1/re_id/0
It has a 0-50mVDC output over its 0-50
psi range. I contacted Honeywell and learned
that their suggested retail price is $268.
I did a more research and found a lower cost and, I
believe, superior replacement. It's a Measurement
Specialties MSP 340 model M3421-000006-100PG
