ERD620 – NUEVO PROBADOR DE VÁLVULAS COMPACTO
Después de 47 años y 250.000 probadores instalados en más de 5.000 clientes en todo el mundo, ATEQ presenta su revolucionario probador de válvulas ERD
Nuevo módulo electrónico, nuevo módulo de medición, nueva interfaz, nuevos accesorios… Todo se ha hecho para mejorar su control de calidad.
El instrumento tiene como finalidad generar una rampa de presión y está a la espera de un evento como la aparición de un flujo (ej: apertura de válvula). Una rampa descendente también puede detectar cuando la válvula se cierra. El instrumento mostrará las presiones del evento y las comparará con los niveles de rechazo. Como opción, el evento de flujo se puede reemplazar por un evento de contacto seco.
ERD620 : APPLICATIONS

ERD620 : TECHNOLOGY
Sometimes a leak can be considered as a “small flow”, or a flow as a “big leak”. When your reject level is too high for other technologies, it may be necessary to use a laminar flow tester. A flow takes place between the pressure line and the leak hole of the part.
Our instrument features a laminar flow element across which our differential pressure transducer is connected.
Every flow generates a pressure difference between the inlet and outlet of the laminar flow element, and this variation is measured by the pressure transducer.
When the fluid (gas) enters the device 1, it moves through a calibrated flow tube 2 which causes a drop in pressure. The pressure drop is measured by a differential pressure sensor 3. The pressure of the part under test 5 is measured by the sensor 4.
