Model 6150AD Dose Ratemeter and Accessories (6150AD1 through 6150AD6)

Automess - North America

1. TECHNICAL INFORMATION CONCERNING THE DOSE RATE METER 6150AD
The 6150 AD series includes a built-in GM counter and additionally provides a probe socket to connect external probes. If a probe is connected, the internal counting tube is automatically turned off; the detector of the probe is now measuring. The type of the probe is automatically recognized. Display range and units are chosen automatically according to the type of the probe. Furthermore, there is no fixed assignment between probe and instrument. The user may connect any probe with any 6150AD, where probe indication will not depend on the 6150AD in use. One pin of the probe socket serves as serial interface and can be used to transmit and evaluate the display (dose rate) of the instrument on a PC. Cables to connect external probes may be up to 100 m long (depending on probe type). Standard lengths available from stock are 1.25 m, 3 m, 10 m, 20 m, 75 m, and 100 m.  

1.1 Model summary

The basic 6150AD models are 6150AD1 to 6150AD6, henceforth generally designated as “6150ADn” (where n stands for 1 to 6). Models 6150AD1/3/5 have the same range of up to 1 Sv/h. They only differ in number and extent of functions, that is in software (EPROM). The 6150AD3 was the more intelligent successor of the 6150AD1. The 6150AD5 is again the successor of the 6150AD3 with additional support for the scintillator probe 6150AD-b. Likewise, models 6150AD2/4/6 have a range of up to 10 mSv/h, where the 6150AD4 was the more intelligent successor of the 6150AD2, and the 6150AD6 again corresponds to a 6150AD4 with additional support for the scintillator probe. In that sense models 6150AD1 to 6150AD4 are outdated (but are still available, particularly the models 6150AD1 and 6150AD2 for those users who prefer easier operation of a simple model). The following Table 1 summarizes all models 6150AD1 to 6150AD6 with their essential features.
 

The additional functions comprise: protection against unintentionally switching off, non-volatile storage of the dose measured with the internal tube, dose alarm, programmable alarm thresholds for dose and dose rate, better resolution (more places after the decimal point) when indicating dose, alarm threshold, etc.

DOSE RATE METER 6150AD-6

The 6150 AD-6 is useful for measuring photon radiation (gamma- and X-radiation) Features include analog and digital display, automatic range switching, non-volatile dose memory, individually programmable dose and dose rate alarm thresholds, indication of relative standard deviation. The 6150AD-6 is powered by a 9V-battery (IEC 6LR61).

Ranges:
Analog range: 0.1 ĩSv/h - 10 mSv/h
Digital range: 0.01 ĩSv/h - 9.99 mSv/h
Energy range: 60 keV - 1.3 MeV
