Absolute
Analogue Servo Encoder (A2SE) is operating on Hall's
effect principle. There is no metallic moving wiper contacting
to element and hence no wear and tear or sliding electrical
noise. Shaft is rotating endlessly in double ball bearings
giving very smooth movement. It has excellent mechanical response
with no hystersis in the output. A2SE is enclosed
in anodized aluminium housing with IP-65 protection. It is
ideal for harsh environment applications.
A2SE incorporates excellent concept of providing
two simultaneous absolute analog outputs without any external
device viz: 0-10 VDC, 4-20 mA and SSI corresponding to 0-3600.
Voltage output can be utilized to monitor the position while
at the same time current output can be used to transmit the
signal at the remote for control. Various outputs can be factory
programmed to suit the different use of angular position.
Its 10 bit SSI output (optional) can be directly coupled with
micro controller for further use.
A2SE can be used in numerous applications, few
of which are: As a Feedback element in Dancer application,
Tilt sensor, Angular Displacement Measurement, valve Positioning
Controls, Robotics, Mobility services / Aids, Marine Instrumentation,
CCTV, Camera Positioning, Medical Scanners, Construction Vehicles,
Vending Machines, Industrial Power Tools, Workshop Equipments,
Front Panel Rotary Controls, Automotive Applications, Wind
Direction monitoring, Replacement of Conventional Servo Potentiometer
for long maintenance free life. |
