Crane Electronics UTA transducer

[Dennis S.]

I'm trying to get a Crane Electronics UTA Rotary Transducer to talk to MAX with no luck. This is a steel drive shaft located in low friction ball bearings. The shaft incorporates a Wheatstone Bridge strain gauge circuit and precision slip ring assembly rigidly attached to the input end of the shaft. You can view it at http://crane-electronics.com, click on Products then Transducers. I'm using a PCI-1200 DAQ card with a CB-50LP I/O connector block. The attachment shows the schematic, but I don't know which to connect to for the power and data. I think the unit is a floating ground but I could be wrong. This is my first project as I am learning LabView and DAQ. Crane Electronics doesn't want to help me other than give me the schmatic. Ca
n someone give me a hand with this?

Dennis,

Sounds like you need to find another vendor for your UTA Rotary Transducer.

However; I can probably suggest a method for getting the answers you need. Contact Crane and ask them how to get a scaled 0-10 volt linear output from the transducer, and/or to recommend a signal conditioning unit or method. I once had to build my own signal conditioner for a high accuracy gas pressure transducer. It cost about $35 and took about two hours to do. All it was was a 24V power supply to supply the transducer, some wires, and a BNC connector to allow me to route the actual signal(I believe it was a referenced signal, referenced to the PS reference) to the breakout box of my DAQ device.

Since I don't know the output of your transducer, I can't say wether or
not you can directly use the 1200 DAQ card to supply the necessary excitation to your transducer, but I would have to guess that you can't, and that you need a 24V power supply. Looking at the schematic doesn't help me at all, so I understand your issue.

Get back in contact with Crane, and TELL them you need to know how to excite the transducer, and what signal to expect and where, and what scale you need to be using.

Good luck
