¡¡¡¡WDJF-1 digital
amplitude-frequency induced polarization instrument
¡¡The apparatus is a new generation frequency domain induced polarization
instrument, which is made by referring to other advanced AC induced
polarization instrument home and abroad. It is characterized by
multi frequency, large transmitting power, and strong anti-interference,
lightweight. The instrument can be extensively applied in metal
and nonmetal mineral resources exploration, city geophysical exploration,
ground water detection and other applications.
Features:
- Large power---- maximum voltage: 800 V, maximum current:
3A, be capable of either constant current or non constant
current supply.
- Multi-frequency measurement: four pairs frequencies from
0.308Hz to 32Hz, adaptive for all kinds of conditions.
- Flexibility of operation----single frequency operation (one
frequency measurement) or double frequency operation (two
frequencies measurement, high frequency and low frequency),
improving work efficiency greatly as data quality is ensured.
- Digital and intelligent----transmitter and receiver is based
on single-chip£¨SCM£©control, simplifying hardware design and
improving reliability, operation with flexibility and simplicity.
- Strong anti-interference----anti-interference is enhanced
by using suppressing 50 Hz disturbances, special anti-coupling
circuit, and software filter. Even in the strong interference
environment where DC induced polarization instrument can not
work normally, it can gain satisfied results.
- Light weight----transmitter 7Kg (2.4 KW) receiver 3Kg.
