COMPACT / REMOTE MAGNETIC
SKF TURNS UP THE HEAT WITH INDUCTIVE FLOWMETER IN STAINLESS
A PORTABLE BEARING HEATING STEEL
SOLUTION

INSTROTECH is pleased to announce a new product development
in Kobold’s MIM Magnetic Inductive Flowmeter. MIM now features
IO-Link, a short distance, bi-directional, digital, point-to-point, wired,
industrial communications networking standard used for connecting
The new portable induction heater TWIM 15 from SKF uses digital sensors and actuators to either a type of industrial fieldbus
medium-frequency technology to heat up roller bearings or a type of industrial Ethernet, a world-first in magnetic inductive
as well as other ring-shaped, metallic components. flowmeters. MIM is now also available in a remote version for medium
temperatures of up to +140°C.
This innovative device heats the bearing mounted with
an interference-fit onto a shaft, generating up to a 90°C The MIM flowmeter was developed for measuring and monitoring
temperature difference between the bearing and shaft, causing smaller- and medium-sized flow of conductive liquids in pipes and
the bearing to expand. This solution eliminates the need to use operates according to the electromagnetic measurement principle.

in a conductor moving through a magnetic field. The electrically
