Coleta de dados da mais alta qualidade com um Instrumento de EM bem leve

O Profiler EMP-400 é a poderosa ferramenta de indução magnética da GSSI. Este produto EMI foi desenvolvido a partir do zero com a utilização de um sistema-fonte próprio de cancelamento e calibração, que levou ao instrumento de sinal mais estável que há no mercado, a um preço acessível.

A estrutura, a parte eletrônica e as bobinas do sistema Profiler foram projetadas para atingir o máximo de estabilidade estrutural e térmica. Essas importantes características minimizam a variação do sinal e mantêm um nível zero preciso e o nulo estável em todas as faixas de freqüência do sistema, evitando o problema comum de variação do sinal que ocorre com o uso de outros equipamentos EMI disponíveis no mercado. Esses instrumentos mais antigos, que não incorporam a eletrônica avançada e o controle por software empregados no Profiler, produzem dados problemáticos que levam a resultados incorretos.

Utilizando-se da tecnologia Bluetooth™, o Profiler opera com um gravador de dados PDA, por conexão sem fios, eliminando assim o ruído causado pelos cabos, o que permite obter os dados de EMI mais precisos do mercado. O Profiler pode ser configurado para medir, simultaneamente, até três freqüências entre 1.000 Hz e 16.000 Hz, com uma separação fixa de bobinas. Ao coletar dados em freqüências múltiplas o usuário pode selecionar as freqüências que        permitam adquirir os melhores dados para cada aplicação. Os dados ficam disponíveis em tempo real para obtenção rápida de resultados no campo.

A aquisição de dados usando a interface gráfica do Profiler é simples e o instrumento pesa apenas 4,5 kg, o que o torna extremamente portátil. O Profiler pode ser utilizado para investigações de sub-solo em áreas acidentadas onde a maioria dos outros instrumentos não funciona por causa das condições inóspitas do ambiente. Isso faz com que o Profiler possa ser utilizado como uma tecnologia complementar aos nossos produtos GPR.

Benefícios do Profiler:

  • Sistema de utilização muito fácil

  • Estabilidade de sinal sem igual

  • Sistema Multi-freqüência

  • Leve – pesa apenas 4.5 kg

  • Gravação de dados sem fios elimina o ruído causado pelos cabos

  • GPS integrado

  • Sistema bem portátil que facilita a movimentação em terreno acidentado

  • Sistema lacrado, à prova de ataques do ambiente, durável e fácil de transportar

  • Várias opções de bateria

  • Obtenção de dados em tempo real  

  • Os arquivos são gravados na memória interna em formato Excel

  • Baixo custo inicial

  • Fornece dados que não podem ser obtidos por qualquer outro método  

Os vários usos possíveis do Profiler incluem:

  • Estudos ambientais

  • Arqueologia

  • Pesquisas Geológicas  

  • Avaliação de áreas

  • Pesquisa de água subterrânea

  • Pesquisas para uso agrícola  

O Profiler oferece nosso sistema a prova de agentes ambientais, comunicação sem fio com o gravador PDA, baterias recarregáveis Li-Ion, carregador de baterias de CA, GPS WAAS, alça para transporte, embalagem resistente para trânsito e manual de instruções.

Contractors and construction professionals can quickly identify tanks, pipes, and leech fields in septic areas using GSSI ground penetrating radar (GPR) and electromagnetic induction (EM) equipment:



Plotted EM data of a septic tank in a residential back yard in southern New Hampshire.  The data shown was collected on a closely-spaced grid with the Profiler EMP-400 and shows a very distinct, high-response target in the middle of the survey area.


Measure Soil Conductivity with GSSI Profiler EMP-400

Soil scientists measure ground conductivity data for evaluating ways to remediate contaminated soils. Ground conductivity measurements are also invaluable to precision agriculture applications, where the GSSI Profiler EMP-400 is used to determine how best to apply fertilizer to farmlands and vineyards.

 


Soil conductivity map of a farm field in North Dakota, USA collected with the Profiler EMP-400 and differential GPS. Data shows areas of high conductivity that are the result of salt intrusion into the overlying soils.




EM is used in environments that have higher ground conductivities, such as clayey soils. The EM data set illustrates the lateral extents of a resistive anomaly common to sinkhole geology. Note use of GPS for data positioning.


Locate Contaminated Areas with GSSI GPR and EM Instruments

Environmental scientists use GPR, EM and other geophysical methods to delineate the extent of former landfills and location of contaminated soils.
