Will the MicroCal calibrate other manufacturers' pressure sensors?

Yes, the MicroCal can calibrate other manufacturers pressure sensors. 

The MicroCal can provide up to 24 VDC excitation to the Unit Under Test (UUT) or it can read the output of pressure sensors that are powered externally. 

The MicroCal has the ability to read both 2-wire, 4-20mA current loop output signals and 3/4-wire Voltage output signals that are up to +/- 10VDC from the UUT.
