Область применения

The Liquitrend QMW43 is developed for the food and beverage industry to help customers to ensure product safety, improve quality and increase the availability of installations. Base your decisions on the unique and reliable measurement of buildup thickness and conductivity via the combination of conductive and capacitive measuring modes.

Cleaning optimization, blending homogeneity monitoring and media differentiation of liquids, suspensions, pasty media etc.

For the use in storage, mixing and process vessels with or without an agitator, pipes and equipment periphery

Process connections: Threads and hygienic connections

Sensor design: Flush-mounted, surface roughness Ra<0.76µm

Temperature: -20 to +100°C (-4 to +212°F), CIP/SIP to 150°C (302°F) for 1 hour

Certificates and declarations: 3A, FDA, EHEDG and EG1935/2005, EN10204- 3.1

Преимущества

Reliable, repeatable and accurate measurement of buildup thickness and conductivity regardless of media type

Conductive as well as capacitive measuring cycles, the device automatically detects the most accurate measuring mode and uses it automatically

Verification of cleaning status without the need to open the tank

Compact and flush-mounted stainless-steel sensor offers the perfect insight into the conditions in pipelines or tanks at all critical locations

Plug and Play - simple commissioning without presettings

Hygienic safety by Design and material traceability are a matter of course

Integrated digital communication option via IO-Link
