load cell

[jyothi prasad]

sir

 i have kistler load cell .i want to interface this load cell to USB 9237 via RJ 50 connector.RJ 50 has 10 pins.now my question is to which pin i should connect my load cell

The easiest way would be to read the manual

Since you did not give a model number I could only guess, so try looking here and match your model number

sir
my kister load cell type:9712B250.the out put of the load cell have to be taken through BNC connector and that should be connected to NI 9237 via RJ50.my problem is RJ50 had 10pins and BNC connector has two pins,now to which pins in RJ50, BNC connector to be connected.

No idea what BNC you are referring to and do not make it hard to get help. Post a link to the actual data sheet or attach the information.

There is a link to the 9237 data sheet, which gives the pinout of the RJ50.

You just need to convert the BNC to the RJ50.  Which they sell RJ50 to wires and you can get a BNC to wires and hook them together.

I just looked at the specs for the 9237 and it says the max input is -25 mV/V , 25 mV/V .  And it looks like your sensor puts out 5 volts, so I don't think it will work the way you want.  You might just need an analog input.

If this is the sensor, it looks like you just need to read the output of the power supply/conditioner which should be a max of 5 volts.

There is load cell and load cell 🙂

Kistler makes piezoelectric load cells for dynamic ampplications, the USB 9237 is designed for strain gage type load cells for more "static" applications.

So for the Kistler sensor you need an IEPE e.g. Kistler 5100 series amplifier/conditioner and any USB DAQ device from NI to read the voltage output of the 5100 unit.

If you need to use the USB 9237, then you have to buy a strain gage based load cell and drop the Kistler one.

Make a choice based on what you want to measure, static loads (strain gage) or dynamic loads (piezo cristal).
