I calibrate all kinds of stuff along with all my other duties supporting mechanical testing systems. Mostly force and displacement but also angle, torque, pressure, strain and even temperature. Oh and acceleration. I work in the field but our metrology department back at the mothership has dead weight calibrators for our field standards we carry.
Pressure can be calibrated in the loop or manually with a strain gage pressure transducer standard. Our systems use pressure sensors for control and data acquisition, and also for control loop stabilization in high inertia systems.
