Pressure Sensor for Flow Bench

[goflo at pacbell.net]

Hi Garfield,

Motorola pressure sensor part # is MPXL5010 0-1.45 psi range (approx
41 in.H2O). Output span is 4.5 V temp compensated on-chip.
Used this part to build a data logger for a SuperFlow 600.
The -dp version of the part reads the test manometer - Output to
LTC1286 12-bit A/D, interrogated by an old hand-held 8-bitter (TI74)
which logged the data for later upload to PC. The thing is fast enough
to see the pressure transients in the flow bench so I've employed active
and/or software filters between the device and the A/D, depending on 
what I'm doing. Seems to work. Keep threatening to close the loop with
servos on the pressure valves!
Motorola's got a Sensor data book with all the variations and some good
app stuff. Hope this is useful.

Jack
