Monitor conveyor belt scale speed in demanding bulk material handling applications with the highly reliable and accurate Thermo Scientific™ Ramsey™ 60-12 Digital Belt Speed Sensor. Direct-coupling the sensor to the conveyor tail pulley, snubbing roll, or large diameter return roller ensures accurate belt-travel readout. No wheels ride on the belt, eliminating problems related to material build-up and slippage. The sensor element uses a brushless, pulse generator to produce a stream of pulses, each representing a unit of belt travel. The pulse stream frequency is proportional to true belt speed.

Description

Models 60-12C, F, G and ENC Speed Sensors must be attached to a pulley shaft which turns at true conveyor belt speed. Normally, the tail pulley shaft or a snubbing roll shaft satisfies this requirement. In installations where the tail pulley or snubbing roll shaft is not accessible, an additional pulley must be installed specifically for the speed sensor.

• 60-12C is used for speeds from 20 to 200 RPM and supplies the output of the generator directly to the totalizer for high speed operation
• 60-12F is used for speeds from 3 to 30 RPM
• 60-12G is used for speeds from 10 to 200 RPM
• 60-12ENC is used for speeds 0 to 200 RPM and has a 500 pulse per revolution encoder inside, typically is used on slow RPM applications
