Introduction To IndiTop Digital

The Alfa Laval IndiTop is an automated indication unit that does not require the use of any solenoid valve. It transmits the status and condition of the valve position to any PLC system using one of two electrical feedback signals either DC/AC or PNP/NPN. LEDs display the current main valve position and on/off power status at all times. . The sensor system accurately detects valve stem movement, the position of the valve at any given time, with an accuracy of plus or minus 1mm through the use of microchip sensors. To locate the current valve position, sensor chips inside the sensor board calculate the angle between the axial magnetic field produced by an indication pin mounted on the valve stem. Each indication unit fits all Alfa Laval hygienic valves and provides a tolerance band for valves to prevent product failure. This indication unit also eliminates the need to readjust the sensors and boosts productivity. . LEDs conveniently display the main valve positions, setup and local fault indication on the indication unit.
