RDP introduces Integral Field Position Sensors.
RDP Electronics Ltd has announced a Profibus-DP
field bus solution for position sensing with the
introduction of new integral electronics versions of the
versatile MTS Temposonics III range of magnetostrictive
Demands for measurement systems with the ability to transmit
data directly from transducer to other devices networked on the
field bus such as PLCs and drives, or to real-time monitoring
locations, depend on smart¹ devices with inbuilt communication
capability. Supplied exclusively by RDP in the UK, the MTS range
of Temposonics long-stroke displacement transducers now
includes a Profibus-DP version for direct digital transmission of
Ideal for long stroke displacements, the magnetostrictive technique
pioneered and perfected by MTS involves the interaction between
a current pulse present in a fixed waveguide and a magnetic field
produced by an adjacent magnet attached to the movable piece.
The waveguide runs the length of the transducer and at the point
the current pulse and magnetic field coincide, an acoustic pulse
- the strain pulse¹ - is generated. The time interval between the
current pulse and strain pulse is proportional to the position of the
magnet. Internal digital processing provides a direct digital output
that is then converted to the Profibus DP protocol.
These versions of Temposonics III sensors now have the capability
to be connected directly to a Profibus-DP network along with drives,
actuators, other sensors and displays, and interact both with the
master controller and other distributed intelligent field devices.
In addition to the Profibus-DP field bus option, RDP¹s range also
includes magnetostrictive position sensors for CANbus, DeviceNet
and SSI industry-standard networks
