Dens-e-mat, Electronic Density Control
The Dens-o-mat Electronic Density Control is an object-pro-grammed exposure control which automatically provides optimalexposure based on patient type, film type, and tooth structure beingradiographed. It incorporates a Line On-Off switch and indicatorlight, selector knobs for Patient Type, Film Type, and Tooth Struc-ture, and is provided with a "dead-man" type exposure switch withcoil-cord for operation of the x-ray system. When the exposure but-ton is depressed, the x-ray ON indicator lights and an audible signalsounds. The exposure is terminated when the exposure button isreleased or when the programmed exposure is completed. This isindicated by the audible and visible x-ray ON indicators going off.
The Dens-o-mat automatically compensates for line voltagefluctuation, consistently providing films with optimal density.
Note: To determine actual mAs, multiply mAs setting bycorrection factors for patient type and film type.Example: mAs Patient Film Actual
setting x Type x Type = mAs2.3 .66 1.5 2.3

Measurement Basis DefinitionskVp - stationary high voltage which settles under load after
the pre-heating time.
Direct measurements in the laboratory using a Philips Elec-tronic kV Meter, F. S. 200kV, with a high voltage divider network,accuracy 1%.
Indirect measurements during production as the high voltageterminals are not accessible. The factors considered are (1) ratedline voltage, (2) turns ratio of the high voltage transformer, (3) peakvalue of the tube current, (4) rated mains resistance, (5) primary re-sistance of high voltage transformer, and (6) secondary resistanceof high voltage transformer. Maximum deviation based on worstcase calculations.
mA - The average value of the stationary current which sett/esafter the pre-heating time.
Direct measurements made at the midpoint of high voltagesecondary using a precision mA meter, F. S. 10mA, class 1.
Time - The first 7.5 pulses (warm-up pulses) are pulses withless than a minimum threshold voltage pulse amplitude and are ex-cluded from the measurement.
Total time consists of "preheating time" and the "exposuretime." The first 7.5 pulses (125ms) during which no significant X-raysare generated, are considered as "preheating time."
The "exposure time" is the time that can be selected andduring which X-rays are generated.
The exposure time is checked with a special crystal-controlledtiming device with an accuracy of 1o-eseconds. The Dens-o-mat istested with a dummy load, at nominal conditions of 120 volts A.C.,at all mAs settings and at each setting of the Patient and Filmselectors. The Dens-o-mat compensates for line voltage fluctua-tions by increasing the exposure duration when the line voltage fallsbelow 120 volts. It reduces the exposure duration when the line volt-age exceeds 120 volts, thus providing consistent film density.
