Automatic and continuous transducer-drift compensator for endpoint detection systems.
Amarillo, TX: U.S. Department of the Interior, Bureau of Mines, RI 8568, 1981 Jan; :1-9
This Bureau of Mines report describes an automatic and continuous transducer-drift compensator. The compensator formed a part of the instrumentation used to indicate the saturation by hydrogen of a cryogenic, adsorption column. It has a variable delayed-response characteristic and will respond only to signals having rise times faster than component drift times. Zero drift due to varying ambient conditions and component aging is nullified. Equations relating the output as a function of the input signal are given.
