For Simulink there is http://www.mathworks.com/help/gauges/index.html but that uses ActiveX and is available for 32 bit Windows only.
There are a series of JFreeChart demos such as at http://www.mathworks.com/matlabcentral/fileexchange/30436-dialplot-demo-2
There is http://www.mathworks.com/matlabcentral/fileexchange/50516-gauges-for-simmechanics Gauges for SimMechanics
Also, http://www.mathworks.com/matlabcentral/fileexchange/37955-two-gauges and http://www.mathworks.com/matlabcentral/fileexchange/21312-activex-control-example-in-gui
And one or two more that are more specific to strain gauges.
Not a lot, but this is what is there.
