mag-flux M1

Magnetic-inductive measuring transducer with synchronised d.c. field

The mag-flux M1 measuring transducer was developed specifically for use with the magnetic-inductive mag-flux-series flow sensors. With an optionally available operating module and a local display, the measuring transducer is easy to adapt to customer requirements.

The mag-flux M1 is a microprocessor-controlled, programmable measuring transducer and can be adapted to the user requirements. While the fundamental configuration, e.g. sensor calibration with parameterisation of these values in the measuring transducer is performed in the plant, the customer can make further settings and required changes at any time. The measuring transducer records and processes the measurement signals from the corresponding mag-flux-series magnetic-inductive sensor. It is suitable for medium flow speeds up to 10 m/s.

The mag-flux M1 measuring transducer is available in both separate and compact designs. This applies in particular when combined with the mag-flux A.
The mag-flux M1 is designed with communication capabilities. With an optionally available additional module, it can also be used with the HART® protocol.

Area of application:

The measuring transducer records and processes the measurement signals from the corresponding mag-flux-series magnetic-inductive sensor. It is suitable for measuring all electrically conductive liquids, slurries, pastes and pulps with a minimum conductivity of 20 µS/cm at average flow speeds of up to 10 m/s.

The mag-flux M1 measuring transducer is used in the following industries:

Plant and mechanical engineering
Fire safety
Chemistry
Building services equipment
Food
Metal extraction, production and processing

Oil and gas
Shipping
Water and wastewater
Cement and minerals

Advantages of the mag-flux M1 magnetic-inductive measuring transducer:

Reliability (long-term stability, service life)
Minimal maintenance requirements
Simple commissioning
High measurement accuracy
Flexible installation position (however the measuring tube must be completely full at all times)
Manufacturer’s application expertise
Short lead times

Special properties of the mag-flux M1 measuring transducer:

Rapid signal processing with 16-bit microcontroller
Simple menu-guided operation with two-line alphanumeric display
Self-monitoring function
Analogue output and digital outputs for pulses, device status, limits, flow direction, frequency output
Internal simulation for all output functions
Password protection to prevent unauthorised access
Multilingual user interface

How the mag-flux M1 measuring transducer works:

The flow measurement principle is based on Faraday´s law of electromagnetic induction, in which the sensor converts the flow into an electrical voltage proportional to the flow speed.

The mag-flux M1 absorbs and processes the electrical voltage, and converts it into analogue and digital output values.

A control unit is available as an option. In addition to a local display, it allows customers to configure the measuring transducer based on their requirements. The mag-flux M1 is designed with communication capabilities. With an optional add-on module, it is also suitable for use with the HART® protocol.
