Pressure / Temperature measurement with Virtual Bench

[Sean0908]

Hi everyone.

I'd appreciate if you help me out here.

I am completely new to VirtualBench (VB 8012) and Labview.

I am trying to figure out if VirtualBench is available to function as data acquisition station like DAQ when it is hooked up with Pressure/Temperature sensor.

There is not much information regarding my question on Internet and I am the only one who is working on VirtualBench in my lab.

I'd like to know how this device works (work flow) if it can be connected to mechanical measurement sensors in order to detect Pressure/Temperature etc.

Thank you.

It would really depend on the sensor, but you do have 2 options for measuring a signal: DMM or oscilloscope.  Neither one will do the conversion into physical units for you though.

Hi Sean,

VirtualBench has a Mixed Signal Oscilloscope, which is different than a DAQ device [1].

I would say VirtualBench would be a good tool to explore a sensor's behavior and characterize its response, but not a good tool to log data during a test or experiment. It's a good exploration tool because it has a power supply, a DMM, and scope channels. You can use the power supply to find the excitation value you want to use and measure how much current the sensor requires as it operates. You can use the DMM and the scope to see the steady-state and transient responses from stimuli. However, once you want to install the sensor in its final setup, you will want a DAQ device that can continuously acquire and stream data, which is something the VirtualBench MSO cannot do.
