The portable TEM instrument system: adopt portable power to achieve high-current power supply. With essential difference between single pulse power supply can realize high power positive and negative square wave power supply, with multiple stacking, no longer rely on the large power generator sets or large batteries.
Working with large current and small coils: adopt high current and small coil power supply, integration advantages of large current positive and negative square wave power supply, exploration depth will up to thousands of meters, especially suitable for field construction conditions with poor. At the same time, the field construction costs and efficiency than the traditional large coil method save 60%.
IPC as a operation platform of master machine with Windows: using low power consumption IPC as operation platform of the computer with Windows, for supply current, pulse width, sampling rate, and times stocking and so on, are all set up by Chinese/English menu; the massive computer storage space provides the guarantee for large-capacity sampling: measurements of a variety of data in one day, are all exists in computer.
Selection of military IPC as operation platform with Windows PE, to operation intelligent and friendly.
Using Light emitting diode as backlight LED screen, the feature with non- noise, highlighting and low power consumption to improve the date quality of field collection.
Adopted dynamic floating amplification method to achieve the signal type collection, then enables our instrument operation simplified and convenience, so that reduce the data quality instability which caused by human factors.
High-strength engineering plastic chassis triad as one of receiver, signal amplifiers, power supply system, with which reduces in size and weight, at the same time , easy to carry and construction.
In humidity and dust environment, Water-proof, dust-proof and full-metal stainless steel of keyboard become more adaptable, it’s more sensitive to protect instrument better and use longer life.
Hot-keys makes field operation become so easy and simple.
The Original over-current protective functions: electric current pass through the receiver to select the matching automatically, and protection circuit.
Good stableness and safety: receiving circuit using the latest high quality chip-Assembly, such as A/D converter with 16-bit 1M/S of high speed chip and low noise, so that make the system has a good performance. Within Instrument transmitter, set up comprehensive over-current and over-voltage protection circuit, make the instrument have a good stability and safety.
High sampling rates: to sampling with high density date for power supply current and secondary field potential. The highest sampling rate up to 1 μ s. the massive date gained from it will provides a good foundation for digital filter, time setting channel, power-off time correction, and abnormal form of research, etc.
Multiple anti-interference technology: for 50Hz interference signal, with frequency and phase auto-tracking measurement and compensation, so that eliminate the interference of working frequency and harmonic, because of the frequency automatically tracking, rejected the previous stiff way of using the standard 50Hz with fixed cycle 20ms as the time unit for date sampling and compensation, when the working frequently rate does not stability, also can obtain a good compensation effect. Unlimited stacks, will reduce random interference.
Advanced Interpretation Software System: With the integration of data acquisition and processing, one dimensional positive and converse inversion, 2.5 dimensional positive and converse inversion, automatic output of the results, it can provide the interpreted results maps on the site. Equipped with professional teacher especially for interpretation on site, we can provide all kinds of help for the users whose have any questions, such as the hardware of the instrument, field methods and the interpretation of the results.
