Overview / Design Principle:
The HS85 digital tachometer incorporates state-of-the-art
magnetoresistive sensing technology. The magnetically
encoded signals provide pulse codes of A, B, and an
optional index pulse Z, with complements (A, B, Z).
These signals are solid for the life of the encoder.
They do not exhibit the unreliable signal drift that
requires a fault check on other digital tachometers.
In addition, this technology is immune to common contaminants
such as water, oil, grease, dirt, vibration, and overall
harsh conditions of operation.
The HS85 was created as a solution to roller or sleeve
bearing motors with excessive axial and radial play.
This digital tachometer is ruggedly designed with steel
flanges, heavy duty motor style bearings, and cast iron
housing. The mill duty construction is ideal for motor
and nonmotor applications, or where the motor casting
is otherwise unavailable. As an example, the HS85 is
perfect for mounting as a line shaft reference encoder.
By virtue of design, the HS85 is more forgiving of older
motors which are unable to hold precise tolerances.
The HS85 is shipped pre-assembled. The installation
is quick and easy; just slip the unit over the motor
shaft, tighten the clamp, and add the anti-rotation
arm. The sensor alignment of the HS85 is entirely independent
of the motor frame. Wiring is simple due to the industrial
duty connectors. No field soldering or crimp pins are
required. Simply strip conductor ends, insert and tighten
the connector screws. The interchangeable stainless
steel sensor modules are available in a wide variety
of pulse counts. There are no field gap checks, axial
alignments, or radial run-out checks required.
.Features and Benefits:
- Easy Installation
- Rugged, cast-iron and steel enclosure and zero-speed,
magnetoresistive sensing technology
- Immune to grease, salt water, dust, and other contaminants
- Heavy duty, double sealed, deep groove, radial ball
bearings to
tolerate axial and radial runout
