Thermo Scientific Ramsey Proline Model 60-12 and 61-12C Speed Sensor

The Thermo Scientific ^™ Ramsey ^™ Speed Sensor. The Pro-Line (Proline) speed sensor is the most reliable and accurate speed-sensing device ever developed for belt scale service. Direct-coupling the sensor to the conveyor tail pulley, snubbing roll or a large diameter return roller ensures accurate belt-travel readout. Its rugged, cast-aluminum housing makes it suitable for outdoor installations. It comes equipped with an AC pulse generator, so there are no brushes to adjust or replace. Monitor conveyor belt scale speed in demanding bulk material handling applications with the highly reliable and accurate Thermo Scientific™ Ramsey™ 60-12 (081648) 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.

Product Description

This sensor is the most reliable and accurate speed-sensing device ever developed for belt scale service. Direct-coupling the sensor to the conveyor tail pulley, snubbing roll or a large diameter return roller ensures accurate belt-travel readout. Its rugged, cast-aluminum housing makes it suitable for outdoor installations. It comes equipped with an AC pulse generator, so there are no brushes to adjust or replace.

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. Part # 003968
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
61-12C/CSA Speed Sensor Part # 081648
