Circuit adds Programmability to sensor Amplifier - 03/21/02 EDN Design Ideas /
(added 1/05)The pressure-sensor amplifier circuit of Figure 1 offers a number of
advantages over the traditional approach using the classic three-op-amp
instrumentation amplifier. The circuit can operate from a single supply and uses only
two op amps and 1% resistors. If the reference voltage, VREF, is 0V, the
transducer....
Pressure Gauge Responds Linearly to Altitude - 03/03/03/94 EDN-Design Ideas /
(added 3/03) You can use a common pressure transducer as an altimeter if you employ a
special technique to make the transducer respond linearly. If you were to simply
amplify the output of a pressure gauge's bridge (VB in Fig 1) by a gain of 32.7 and an
offset of 3.2V, ....
Use RS-232C Port to Measure Pressure - 08/01/97 EDN Design Ideas / (added 8/03)
A simple circuit and accompanying software turn a pressure sensor into an accurate and
cheap pressure digitizer that works with any PC's RS-232C COM port. Many manufacturers
make micromachined silicon piezoresistive pressure sensors.
