New Angle Sensors.
Part of the Schreiber Messtechnik range of inductive displacement sensors recently introduced to the UK , is the SM60 series for measurement of
This range of inductive angle transducers offers measurements from 30° up to 90° full-scale range. Most types are available with built in electronics requiring a simple DC voltage supply, with the rugged SM62 model having either voltage or 4-20mA output signals. Standard accuracy is specified at less than 0.5% full scale, but more accurate options are available if required.
The operation principle of the inductive sensors, involves a nickel iron core rotor moving through two coils of a differential choke. The position of the rotor leads to an inductance variation in the coils and either internal or external electronics converts this variation into a signal proportional to the angle of rotation. Units without built in electronics require external conditioning which can be supplied in either single channel rail mount modules or multi-channel modules, which contain the oscillator and demodulation required for this type of sensor.
These transducers complement the existing Techni Measure range of low cost potentiometers that can also be used for angle measurements, but the SM60 series offer longer life (no contact wiper), greater accuracy and environmental protection to IP65.
