Prosig USA, Inc. Data Acqisitiion Tacho Card

The 8420 card is intended as a solution for situations with rotating machines where positional information and time relative to position information are required. This would classically be a very high speed shaft encoder with a fine resolution. This card is used in applications where there is a requirement to accurately measure rotational speed at several points in a drivetrain. The high speed and resolution of this card mean it is suitable for in-depth rotational machine analysis such as torsional and angular vibration. The 8420 card measures the time between pulses with a 16ns resolution. Programmable signal conditioning to de-bounce inputs 60MHz resolution Pulse counting Noise Offset’ & ‘Hold Off’ setting Programmable threshold & slope Pulse time stamping
