Force sensor combines accuracy and robustness
The new, improved FSL Series Low-Profile Force Sensor from the Sensing and Control Business of Honeywell is a cost-effective, instrument-grade, precision force-sensing product.
Its rugged housing and IP67 sealing ensure durability in harsh operating environments while features such as integrated reverse polarity, short circuit and EMC protection conform to industry standards.
The sensor has a 90deg measuring range with 360deg allowable rotation.
This gives a wide operating angle tolerant to over-travel.
RPN Series rotary position sensors use a magnetically biased Hall effect integrated circuit (IC) to accurately sense angular movement of the actuator shaft.
The IC, together with conditioning and protection circuitry and two permanent magnets, is sealed in a rugged package with integral connector.
Rotation of the actuator shaft changes the Hall effect IC's position relative to the magnets.
This results in a change in the flux density detected by the Hall effect IC as the shaft is rotated.
The output of the IC is then converted to a linear output over 90deg of travel.
Supply voltage is 10 to 30 Vdc and temperature range is -25degC to +85degC.
The measuring range is ñ 45deg and mechanical angle of rotation is 360deg.
