Interruptores de presión diferencial

Los interruptores de presión diferencial actúan cuando la diferencia de presión entre dos puertos alcanza un punto de ajuste. Los productos de esta categoría abarcan interruptores diferenciales de metal y plástico de ACI, Omega Engineering y Dwyer Instruments, interruptores industriales SPDT y DPDT, interruptores mecánicos OEM, interruptores de control de aire, interruptores diferenciales bajos, diseños de contacto flotante y rangos ajustables en H2O o Pa.

Las aplicaciones incluyen:

  • Alarmas de bloqueo de filtro y de prueba de flujo de aire
  • Presión estática del conducto y control de la compuerta
  • Enclavamientos de estado de ventiladores, sopladores y equipos
  • Puntos de alarma de presión diferencial industrial

Elija según el rango de punto de ajuste, la repetibilidad, la banda muerta, la clasificación de contacto, la carcasa, la compatibilidad con los medios y si el interruptor se utiliza para alarma o control.
