BRL (Ballistic Research Laboratory) Calibration Procedures for Ballistic Pressure Transducers

Pagination or Media Count:
Current procedures used for the calibration of ballistic pressure transducers at BRL are described. Checks include evaluation of continuity, hysteresis, and zero return characteristics as well as calibration against a dead weight system. Static versus dynamic response behavior is evaluated with the aid of a high pressure dynamic positive step calibrator. For the most exacting measurements, adapters are used permitting calibration of transducers in the same mechanical environment as during measurement. Recommended recalibration intervals are indicated.
