STATE OF ART INSTRUMENTATION FROM AN INNOVATIVE COMPANY
ORE FACE SCANNING SYSTEM (GM Based) [ Type : FS 900 ]
Print
Technical Data

Uranium Ore Face Scanning System, Type : FS900 manufactured by Nucleonix Systems is exclusively designed to meet the requirements in Uranium mines for oreface scanning and bore hole loggining for mining purposes to estimate the ore grade.
Measuring Unit developed by Nucleonix Systems is a compact, light weight, portable and battery powered unit.
System essentially has three parts consisting of
(a). Electronic measuring unit
(b). Face scanning probe assembly comprising of a detector with adequate shielding is 2p geometry and a long connecting cable.
(c). Bore hole logging probe with a long connecting cable between the probe and measuring Unit.
Unit has three modes for data acquisition namely CPS, CPM and GRADE. In GRADE mode when operated this instrument directly reads, computes and displays ore grade in ppm. Of course the reading is updated on each time constant (TC).
Initially, this unit is to be calibrated using ore standards. First BG (Background) and averaged BG is acquired and remembered by the unit. Then user can place one to three standard graded samples and enter their values into the system. Once this is done, unit gets calibrated and is ready for use.
