Alfa Laval Indication units Sensing and control

Introduction

The Alfa Laval Indication unit - Inductive is an electrical feedback

unit that offers cost-effective operation and standard

functionality for automated indication on the inductive side of Alfa

Laval butterfly valves. Straightforward and easy to use, this

indication unit provides information about valve operating status

24/7 while boosting productivity.

This inductive indication unit is compatible with any

programmable logic controller (PLC) with a PNP/NPN interface.

Application

The electrical indication unit is designed with inductive sensors for

use with Alfa Laval butterfly valves in hygienic applications across

the dairy, food, beverage, biotechnology, pharmaceutical and

many other industries.

Benefits

• Durable and cost-effective

• Precision operation

• Long service life

• Easy to operate

Standard design

The Indication unit – inductive consists of steel and

plastic components, seals, contact pins, and cable connection

with socket, screw and cable gland. Easy to mount, this indication

unit does not require any mechanical adjustments and must be

installed between the air-operated actuator and the valve.

Working principle

The Alfa Laval Indication unit – Inductive sensor is an

inductive proximity switch that has non-contact electronic

switching elements. It is activated by an electromagnet device

known as a roller leaf. The standard output signal is always

a digital signal (on/off) indicating the position of the valve.
