1.4 Field of Application (Intended Usage)
The integrated flow monitor of a Loctite controller in connection with the Preamplifier
Online Monitor 97211 is used for monitoring the quality and quantity of adhesive
dispensed on parts, i.e. the flow monitor recognizes and evaluates dispensing defects
with respect to quality and quantity. Such defects include:
– Air bubbles in the dispensing system
– Pressure changes in the dispensing system
– Lost or clogged dispensing nozzle
– Touch down of dispensing nozzle onto substrate.
It has been designed specifically for applications requiring high accuracy in dispensing
Loctite adhesives. It is an ideal tool for quality assurance. The flow monitor is used
mainly in the following types of workstations:
– Manual work stations handling precision manufacturing jobs or safety relevant parts.
– Assembly lines with robot stations.
– Assembly lines with automatic in-feed and out-feed.
– CNC workstations.
Necessary Loctite controllers:
– Automatic Controller 97123 or
– Dual Channel Automatic Controller 97103.
In order to integrate such a monitoring system in the production process a special
dispensing valve with an integrated pressure sensor is required.
