Sensor de nivel de líquido: CO2, butano y propano

Datos técnicos: HBLC-CO2

Los sensores capacitivos de nivel de líquido HBLC-CO2 se utilizan para medir niveles de líquido en sistemas industriales, p. ej. CO2, butano y propano. El sensor transmite una señal de corriente de 4 a 20 mA (4 mA cuando el transmisor no registra líquido y 20 mA cuando todo el transmisor está rodeado de líquido).

El sensor está diseñado en acero inoxidable y se puede utilizar en entornos corrosivos. El sensor debe alimentarse con 24 V CC a través de una barrera Ex, que debe ser una barrera de interfaz aislada galvánicamente aprobada y certificada colocada fuera de la zona peligrosa. El sensor tiene un diseño de 2 cables con salida analógica con 4 mA (tanque vacío) y 20 mA (tanque lleno). La salida analógica se conectará a la barrera Ex. Con el sensor no se suministra la barrera Ex que debe pedirse por separado.

El sensor se puede configurar para el tipo de líquido en la HB-Tool, que se puede descargar de nuestra página web. Por favor mira el “HB-Tool”. El diagnóstico también es una posibilidad con la herramienta. La programación debe realizarse en un área no peligrosa.

La gama de sensores incluye sensores para zona 0 y 1 según ATEX / IECEx. Los sensores se pueden utilizar en la categoría de dispositivo 1G y en la clase de temperatura T1 ... T6.

Se incluye un cable de 5 m con conector M12 tipo IEC61076-2-101.

Applications

 Applications

  • Process plants
  • Storage tanks

Intrinsically Safe design:

Intrinsically Safe (IS) sensors are designed and wired to work on such a low current and voltage that it cannot possibly ignite flammable material. By limiting the energy available within the defined hazardous area, electrical equipment can operate safely even amid hazardous mixtures of gasses.

The HBLC sensor is designed for many kinds of liquidsbased on the dielectric constant. The liquid type is selected in the HB-Tool. 

The measuring principle and the influence of the dielectric constant:

Capacitors are designed with minimum two conductors, where one of them is electric isolated. The dielectric constant are key for operation of capacitors, the capacity size is measured in pF.

Dielectric constant (Relative permittivity) is a unique value on a scale of 1 to 100. The value can be seen as a media’s DNA, because it`s unique and related to the molecular structure and polarization.

The Dielectric Constant is always greater than or equal to 1. The larger the dielectric constant, the more charge can be stored (like a battery).

The dielectric constant changes with temperature and pressure, the sensor comes with automatic temperature compensation calibrated/adapted to the measured media.
