3 length sensor conversion bracket with 6-pin ms connector 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. ordering information model no. description part number lscb length sensor conversion bracket, w/10' cable lscb1000 length sensor conversion bracket, w/25' cable lscb1025 length sensor conversion bracket, w/50' cable lscb1050 -- hinge clamp assembly for length sensors & conversion bracket (above) lsahc001 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 corrected measurement. counter or rate indicators with input scaling can compensate for measuring wheel wear and material elastic and compliance errors. in addition, english/metric conversions may also be accomplished (see rlc catalog for more information) . 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). selecting appropriate wheel size & ppr (pulses per rev.) of rotary pulse generator length sensor accessories separate length measuring wheels - dimensions in inches (mm) cast alum. .376" (9.6) bore +.001" -.000" 8-32 unf set screw 3/8" (9.5) round section replaceabl e tire .210" section dia. black neoprene diamond knurled aluminum tread 10-32 un f set screw 1" (25.4) alum. cast .376" -.000" +.001" (9.6) bore .376" (9.6) bore +.001" -.000" tan, smooth polyurethane tread 10-32 unf set screw alum. cast 1" (25.4) of wheel code ok wheel code for use on: metal, paper, foil, film and hard plastics. line contact on material being measured, convenient when available measuring track is narrow or for measuring on end of roller beside passing material. max. speed: 600 rpm for use on: soft, smooth materials such as soft paper, matting, cardboard, fine weave textiles. broad wheel tread minimizes contact pressure and tan polyurethane tread minimizes marking. max. speed: 600 rpm balanced version of 1ft. circumference available. balanced to ansi s2.19- 1989 uality grade 6.3 3000 rpm. for use on: rubber, coarse weave fabrics, rough wood surfaces, foam, insulation. max. speed: 600 rpm balanced version of 1ft. circumference available. balanced to ansi s2.19- 1989 uality grade 6.3 3000 rpm. or wheel code
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 ? to ? turn. ordering information .88 (22.4) 2.9 (73.7) 3.4 (86.4) 2.5 (63.5) 1.25 (31.8) .25 (6.3) l ock washers (2) must be installed between bolt heads and top clamp piec e. e- clip retaining ring (2 ) must be installed in slots . 5.70 (144.8) 4.50 (114.3) (50.8) (38.1) 0.75 0.75 (19.0) 4x ? 0.31 (7.9) 2.00 1.50 (19.0) single wheel 2.93 (74.4) dual wheel 4 (101.6) (21.6) .85 single shaft units this wheel and shaft omitted on .88 (22.4) wheel radius 1.9 (48.3) 6. 9 (175.3) front view top view dimensions in inches (mm) caution: downward tension on signal cable can cause wheel(s) to lift. make sure cable is clamped to machine frame near encoder and allow slack. note: the weight at the length sensor unit provides sufficient traction for accurate operation when mounted as shown, with arm angle from horizontal not exceeding 30, and with hinge clamp toward the far extreme of the extension arm. length sensors should be mounted so measuring wheel(s) contact ribbon, strip or web as it passes over a roller. as an alternative, wheel(s) can be driven by roller surface next to material being measured. model no. description part number lsahc lsahc001 length sensor hinge clamp assembly model lsahc - length sensor hinge clamp assembly note: after installation of measuring wheels, ensure guards,shields or other devices are in place to protect personnel from rotating equipment. wheel code circumference tolerance part number 1 foot (1/3 yd) 0.35% wf1000ok ok 1/3 meter 0.30% wm0333ok 4/10ths yard 0.30% wy0400ok 4/10ths meter 0.30% wm0400ok bk (balanced) 1 foot (1/3 yd) 0.35% wf1000bk replacement tires for or wheels 1 foot (1/3 yd) torf1000 1/3 meter torm0333 4/10ths yard tory0400 4/10ths meter torm0400 tolerance wheel code circumference part number 1 foot (1/3 yd) 0.40% wf1000or or 1/3 meter 0.40% wm0333or 4/10ths yard 0.40% wy0400or 4/10ths meter 0.40% wm0400or 1 foot (1/3 yd) 0.35% wf1000of of 1/3 meter 0.30% wm0333of 4/10ths yard 0.30% wy0400of 4/10ths meter 0.30% wm0400of bf (balanced) 1 foot (1/3 yd) 0.40% wf1000bf wheels & replacement tires for code or wheels ordering information model zgh shown model zfh shown red lion controls headquarters 20 willow springs circle york pa 17406 tel +1 (717) 767-6511 fax +1 (717) 764-0839 red lion controls china unit 302, inan plaza building 13, no.99 tianzhou road shanghai, p.r. china 200223 tel +86 21 6113 3688 fax +86 21 6113 3683 red lion controls europe softwareweg 9 nl - 3821 bn amersfoort tel +31 (0) 334 723 225 fax +31 (0) 334 893 793 red lion controls india 201-b, 2nd floor, park centra opp 32 mile stone, sector-30 gurgaon-122002 haryana, india tel +91 984 487 0503
