Antena com lente de gotejamento com frequência de transmissão de 80 GHz para aplicações de transferência de custódia

Micropilot NMR81 é usado para aplicações de transferência de custódia e controle de estoque com certificações NMi e PTB e atende aos requisitos segundo as normas OIML R85 e API 3.1B. NMR81 é especialmente adequado para aplicações de espaço livre de até 70m. A antena de lente de gotejamento com frequência de transmissão de 80 GHz produz um ângulo de feixe fortemente focado de 3° e evita obstáculos mesmo perto da parede do tanque.

  • Benefícios

    • Hardware e software desenvolvidos de acordo com IEC 61508 até SIL3 (em redundância homogênea) para alto nível de segurança

    • Máxima confiabilidade com precisão até ±0,5mm (±0,02")

    • Desenvolvido de acordo com as recomendações internacionais de metrologia,...

  • Campo de aplicação

    Antena de lente de gotejamento de 80 GHz adequada para aplicações de espaço livre até 70m oferece feixe de alta focalização para aplicações com bocal situado perto da parede do tanque.
