Acoustic Calibrators
-
When you're ready to take noise measurements, it's strongly recommended that you perform a field calibration using an Acoustic Calibrator. You should calibrate your sound meter before you start to measure, and then once you've finished you should perform a reference check against the calibrator and make note of any drift that has occured. You can find out more about performing Field Calibrators by reading this post and watching a short video.

Incremental Encoders
-
Versatile, compact and flexible – Incremental encodersIncremental encoders are used when retention of absolute position upon power loss is not required. These encoders provide information about the position, angle and number of revolutions. The number of lines per revolution determines the resolution. The current position can be determined by counting these pulses from a reference point. Upon activating the machine, a reference run to the reference point is required to determine the absolute position of the encoder.
