The Ramsey Series 20 Belt Scale System with
Micro-Tech 2000 Series Integrators

Designed for general in-plant conveyor­belt weighing applications in the most
demanding industrial environments,
the Series 20 Belt Scale System lets
you control feed rates to crushers,
mills, screens and other processes
with incredible accuracy.

It can monitor production output and
inventory or control loadout of product,
while providing vital information for
the management and operation of
your business.

The Series 20 combines the proven
reliability of the Ramsey 10-20
Weighbridge and 60-12 Speed Sensor
with the power and versatility of the
advanced electronics of the Micro-Tech
2000 Series Integrators.

Easy Installation

Easy to install, indoors or out, on fixed
or portable conveyors, the Series 20’s
rugged construction is designed for
harsh applications including:

Weighbridge

Rigid and rugged, the Ramsey 10-20
Weighbridge remains permanently aligned
within the conveyor frame. The one-piece,
drop-in style 10-20 is completely assembled
at the factory and is quickly and easily
installed and aligned in the conveyor.
It is designed to provide additional stiffening
and support to minimize conveyor deflection.

Both the single and the dual idler models
offer three point suspension and employ
trunnion-type, frictionless pivots. These
sealed units are impervious to vibration,
moisture and product build-up, eliminating
the problems commonly associated with
knife edges and bearings.

Belt Speed Sensor

The Ramsey 60-12 Digital Belt 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 the large diameter lagged
return roller assures an accurate belt-travel
readout. No wheels ride on the belt, which
eliminates problems related to material
build-up and slippage.

Weighbridge Advantages

• No moving or wearing parts

• Precision, strain-gauge loadcell
applied in tension to guarantee
loadcell alignment and accuracy

• A total deflection on weight idler(s)
of less than .004 inches

• Slim profile to minimize material
build-up

• Optional counter-weighted carriages
for light belt loading applications

Belt Speed Sensor Advantages

• Rugged, cast-aluminum housing
suitable for outdoor installation

• A.C. pulse generator no brushes
to adjust or replace
