Princípio de medição de pressão

Sonda de nível confiável e robusta com célula de cerâmica para medição e HART

Geralmente, o transmissor Waterpilot FMX21 com célula de cerâmica capacitiva e livre de óleo é usado em aplicações de processo e ambientais para medição de nível hidrostática. Com a saída HART, as faixas de medição podem ser ajustadas livremente e a medição de nível com compensação da densidade pode ser ativada. Ele é certificado para água potável e oferece medição da temperatura integrada. Há também versões para aplicações em efluentes e lodo ou em água salgada.

  • Benefícios

    • Sensor de cerâmica robusto, de alta pureza (99,9% Al2O3) resistente à sobrecarga

    • Expansão flexível de 4 a 20 mA com saída HART 6.0 sobreposta

    • A mais alta precisão de nível usando correção de densidade com compensação de temperatura

    • Medição simultânea de...

  • Campo de aplicação

    Três diferentes versões para água potável, efluentes e esgoto, água salgada.

    • Conexões de processo: braçadeira de suspensão, prensa-cabo

    • Temperatura: –10 a +70°C (14 a 158°F)

    • Faixa de medição: 0 a 20 bar / 200 m H20 (0 a 300 psi / 600 pés H2O)

    • Precisão: ±0,2...
