Description

3.1

Overview

SITRANS F M Transmag 2 is a pulsed alternating field magnetic flowmeter where the
magnetic field strength is much higher than conventional DC pulsed magnetic flowmeters.
This makes it ideal for difficult applications as:
● High concentrated paper stock > 3 %
● Heavy mining slurries
● Mining slurries with magnetic particles
The complete flowmeter consists of a flow sensor 911/E and the associated SITRANS F M
Transmag 2 transmitter.
Transmag 2 is available in a remote or a compact version. The 911/E sensor is available
with diameters from DN 15 to DN 600 (½" to 24").
As a standard protective washers are fitted permanently on all PTFE-coated sensors to
protect the coating.

Operating principle

SITRANS F M Transmag 2 is a microprocessor-based transmitter with a built-in
alphanumeric display in several languages. The transmitters evaluate the signals from the
associated electromagnetic sensors and also fulfil the task of a power supply unit which
provides the magnet coils with a constant current.
The magnetic flux density in the sensor is additionally monitored by reference coils. Further
information on connection, mode of operation and installation can be obtained from the
sensor data sheets.
