Page 9: Principle Of Operation
Principle of Operation 4.1 General The SWTD-1000 is controlled by a microprocessor. It works according to the period measurement principle whereby the input period is measured with subsequent computing of the reciprocal value corresponding to the frequency or speed. The relationship between frequency and speed is established with the Machine factor. -
Page 10: Machine Factor
Operating Instructions SWTD-1000 DYNALCO 4.2 Machine Factor The machine factor establishes the relationship between sensor frequency (Hz) and corresponding speed (RPM). Machine Factor = Frequency If the # gear teeth and RPM are known, use the following formula to calculate corresponding frequency:... -
