Descripción

Cámara termográfica OGI FLIR GF77a

para monitorización de escapes de gas

La cámara termográfica FLIR de detección de gases FLIR GF77a es la primera cámara OGI autónoma no refrigerada de detección de fugas diseñada específicamente para detectar y visualizar el gas metano. Esta solución asequible de cámara fija proporciona las características necesarias para monitorización permanente de una instalación de metano, controlando en todo momento que no se producen fugas de metano. La cámara OGI FLIR GF77a es pequeña y ligera e incorpora características patentadas de FLIR, como el Modo de Alta Sensibilidad (HSM) para una mejor visualización del gas.

Solución OGI fija y asequible

La cámara OGI FLIR GF77a es una forma eficiente para las empresas del sector petroquímico y de distribución de gas de mantener sus instalaciones seguras y cumplir con los estándares de reducción de emisiones. La GF77a es ideal para aplicaciones de monitorización 24/7, ya que dispone de características líderes en la industria para vigilancia OGI permanente, incluyendo el Modo de Alta Sensibilidad, enfoque motorizado remoto y arquitectura abierta para la integración de terceros.

Detección y visualización de gases industriales

La cámara FLIR GF77a utiliza filtros espectrales para detectar los gases de metano, con lo que se logra mejorar la seguridad de los trabajadores y la identificación del punto de fuga sin necesidad de inspección presencial.

Conectividad estándar

La cámara térmica OGI FLIR GF77a que cumple con los protocolos GigE y RTSP, con lo que se consigue máxima flexibilidad y estandarización en comunicación industrial, nunca ha sido tan fácil la detección remota de fugas de metano.
