Rectification power large power intelligent underground geological
exploration equipment
Overview
The new generation DC IP transmitter system is composed of WDZ-5A
rectification power (contained balanced load controller) and WDFZ-5
large power intelligent transmitter. This system breaks through the
conventional design mode; uses chip microcomputer for controlling,
and is driven by intelligent IGBT. It has high measurement
accuracy, multi-functions and high dependability. It is small and
light, and can be carried conveniently. It also has the perfect
function of the over-voltage, over-current, open circuit protection
and personal safety protection and so on...

The WDJS-3 series multi-channel digital DC IP receiver uses a
short-wire working mode. It can be powered by a WDFZ-5T or WDFZ-10T
high-power intelligent transmitter. Multiple receivers can receive
at the same time, and the receiver is equipped with multiple
channels that can be measured simultaneously, which doubles the
working efficiency. The instrument can directly measure and store
self-potential, primary field potential, and apparent
polarizability in 4 different time periods. It can also measure and
store secondary field attenuation curves, providing absolute
flexibility for later data analysis and processing. It is widely
used in metal and non-metal mineral resource exploration,
groundwater search, and engineering geology.

Multiple transmission channels, comprehensive understanding of the
spatial distribution of the ore body - by selecting the PDGK-1
multi-channel electrode controller and PDGZ-1 multi-channel
electrode converter, multiple power supply electrodes can be
connected at the same time, and any pair of electrodes can be
selected for power supply during operation.
Support multiple synchronization modes - The instrument supports
software synchronization, quartz clock synchronization and GPS
synchronization (optional). It can be used with ordinary digital DC
IP receivers to form a traditional IP measurement system (only
using software synchronization), and can also be used with our
newly designed WDJS-3 series multi-channel digital DC IP receivers
to form an efficient, multi-channel, high-performance IP
measurement system that supports multiple synchronization modes.
