Anyone know of a triaxail accel compatible with a -24 vdc power supply?

John,

What's your application? Sounds like a Bentley system?

The standard ICP-type accelerometers require a constant current source of around 4 mA at a maximum voltage of between 18 - 24 volts.

A fairly simple switching power supply circut could convert the negative voltage into a positive ICP supply, enabling the use of standard accelerometers. Using more commonly available accelerometers would probably offset the cost of the conversion circuit.

If you provide details of what you're connecting the accelerometer to, I'll sketch up a circuit.
