We strongly recommend reading this manual, and any manual for a product used in conjunction with the SITRANS WS100 (such as a belt scale integrator), for proper installation and operation of any component of the weighing system. Adhering to the installation and operating procedures ensures a quick, trouble-free installation and allows for the maximum accuracy and reliability of your weighing system.
• Long bearing life Eight pulses are generated for each rotation of the SITRANS WS100 shaft. These pulses are typically fed into a Milltronics belt scale integrator. The integrator interprets the pulses and uses them in the calculation of belt speed, flow rate, and material totalization.
• WS100 standard: CE, C-TICK • WS100 IS: uses CE, ATEX and CSA approved Pepperl + Fuchs Proximity Switch and IS Switch Isolator (See Switch and Isolator Approvals on next page.) Page 4 SITRANS WS100 Speed Sensor – INSTRUCTION MANUAL 7ML19985LU01...

Mounting The input shaft on the SITRANS WS100 is coupled to the rotating shaft on a belt-driven pulley with a tapped hole, and is externally supported. The unit’s arresting strap stops it from rotating with the shaft and can be fitted to any rigid support member close to the sensor.

M12x1.75. If using magnetic connector, mount to shaft face, and go to step 3. WARNING: Exercise caution when completing step 1, and remain within specified tolerances. Thread the SITRANS WS100 onto the machine shaft using 16 mm or 5/8" open-ended wrench and releasable thread-locking adhesive (Loctite or similar). 25 mm (1")
² made with three-wire shielded, 0.324 mm (22 AWG) cable. To connect the SITRANS WS100 IS unit to the switch isolator, use two-wire shielded ² 0.324 mm (22 AWG) cable. Use the same cable to connect the switch isolator to the integrator.
