MAGNETOELASTIC DYNAMOTER DYNAMAG

DynaMag allows non-contact mechanical tension measurement in prestressed steel parts of concrete constructions, suspended bridges and ground anchors.

Prestressed steel parts of concrete constructions are used as a sensor component of DynaMag system.

DynaMag advantages 

Simple and clear tenet

• the tenet is based on utilization of physical principles

Non-contact and non-destructive method

• no direct physical contact between the sensor and the measured element
• allows measurement of mechanical stress through anti-corrosive protection of prestressed elements without damaging them
• link between the meassured element and the sensor is provided purely by means of magnetic field

High accuracy and long term reliability

• sensors include neither moving parts not parts that are liable to material ageing and performance reductio

Direct measuring method

• prestressed parts of structures are direct components of the sensor

High resistivity of sensors

• sensors are resistant to dust, shocks, vibrations, water, salt water, water under pressure, chemicals and radioactivite rediance

Unlimited lifetime of sensors

• the life span of sensors exceeds the life span of standard constructions

Sensors cannot be overloaded

Simple installation

• Only for ferromagnetic materials
• Requires laboratory calibration for new or unknown materials

• are designed for measuring and monitoring of prestressed elements of structures such as wires, bars and cables
•  have shape of hollow cylinder, in middle of which the measured element passes through
• can be placed on free parts of prestressed elements, can be sealed in concrete or can be part of prestressed elements of anchor systems
• can measure overall mechanical stress in prestressed elements or can measure stress in individual strings of prestressed cables
• are equipped with electronic identifier and accurate thermometer which measures the temperature of the structures in the sensors area
• enables measurement of mechanical stress with resolution under 1 Mpa in serious industrial environment where usage of other methods is limited or impossible

Readout box

• portable device intended for gathering measured data from sensors
• enables measuring of prestressed elements of diameter from 5 mm to 240 mm
• power is supplied by 24V accumulator or line adapter
• notebook connection for data collecting and evaluation
