mounted, slotted disc. An internal pulse-shaping amplifier circuit delivers a
rectangular pulse signal from the current sinking output in response to the passing
slots as it rotates. They can be direct-coupled to a machine shaft by means of a
flexible-bellows, spring, or rubber sleeve type coupling that allows for axial and
radial misalignment. They can also be coupled with light instrument timing-belts.
Timing-belt drives also allow convenient gear-up or gear-down speed ratio
changes that can be useful for obtaining non-standard PPR rates.

The units contain an L.E.D. light source and a photo sensor that scans a shaft-

MODEL ZHG - HEAVY-DUTY SEALED HOUSING
(Replaces Model RPGH)

These heavy duty units feature a heavy cast aluminum housing with 1/4"
thick aluminum cover plates and 0-ring seals. Heavy duty bearings are double­sealed and allow radial shaft loading of 40 lbs (18 Kg).

A 1/2" (12.7 mm) NPT Conduit entry permits signal wiring to be run via flex­conduit to an internal terminal block. Electrical characteristics are identical to
those for the Model ZBG. Terminal board markings correspond to the Pin-Out
identification of the ZBG.

use these outputs as conventional “Open-Collector” outputs as long as
the supply voltage for the ZB is supplied by the indicator or control
receiving its output signal. The ZB’s internal load resistor also allows the
output to be used as a current source, however, load current must be

ADAPTS APPROPRIATE ZBG and ZBH ROTARY PULSE GENERATOR TO LENGTH MEASUREMENT

DESCRIPTION

This conversion bracket allows the customer to assemble a custom length

sensor by purchasing the following items separately.

1. Length Sensor Conversion Bracket (P/N LSCB1000)

2. An encoder with appropriate connector, PPR and output type.

3. One or two measuring wheels. Install OF & OK measuring wheels with set
screw hub facing encoder shaft (as shown). Apply thread locking material to
wheel set screw threads during installation to the encoder shaft.

4. Hinge Clamp Assembly (P/N LSAHC001)

Note: To complete installation, insure guards, shields or other devices are in
place to protect personnel from rotating equipment.

The tubular arm length of this bracket, related to the wheel axis center-line of
the encoder is 6.8" similar to the length sensors. The 10´ long, 4-wire, shielded
cable with 6-pin MS connector (included with conversion bracket) has the same
color coding as described for the encoder cable P/N CCARPG01. Screws for
mounting the conversion bracket are included.

LENGTH SENSOR MEASUREMENT ACCURACY

Factors which affect measurement accuracy include Measuring Wheel
accuracy and wear, and material conditions. Ideally, materials which are hard,
thin and strong provide good readings, conversely, soft, thick and elastic
materials can present problems in obtaining true readings. The great majority of
these situations, where this effect is consistant, can be compensated for by
applying a multiplier to the quadrature output pulse train so as to obtain a

SELECTING APPROPRIATE WHEEL SIZE & PPR (Pulses Per Rev.) OF ROTARY PULSE GENERATOR

When the desired output of a length sensor and wheel combination is either in feet or inch units, selection
of the proper combination is relatively straight forward. For example, with a 1-foot wheel circumference, a
1 PPR Rotary Pulse Generator will deliver 1 pulse/ft, 12 PPR would deliver 12 pulses/ft (1 pulse/inch); 100
PPR would yield 100 pulses/ft; and 120 PPR would permit measuring to 1/10th of an inch (1/120th of a foot).

The Length Sensor Hinge Clamp Assembly provides an easy method for
attachment and mounting of the Length Sensors and LSCB1 Conversion
Bracket. The removable top on the solid zinc LSAHC mounting block
allows quick installation of the Length Sensor handle tube and provides
secure clamping retention. The mounting block pivots freely in zinc right
angle brackets to allow mounting the assembly via clearance holes for 1/4"
dia. bolts.

The lock washers must be used as indicated (between the bolt head and
the top clamp piece). Assemble the top clamp piece as follows.

1. Tighten both bolts so that the top clamp half draws down evenly on

the sensor tube.

2. Tighten the bolts until both lock washers are flat.

3. Then turn each bolt an additional ½

to ¾ turn.
