1. Introduction

The RL1800 Series Weigh Modules are designed to accommodate normal vessel
expansion in all directions while still exercising self-checking capabilities. The
center-pivoting, tension loading design incorporates spherical washers and a unique
pivoting trunnion that self-restores to its center position. Vessel leveling and
adjustment can easily be done with the center loading bolt, and the load cell can be
replaced without raising the vessel.

The module is available in two sizes. The small size accepts load cells with
capacities from 250lb to 5,000lb. The large size accepts load cells from 5,000lb to
10,000lb capacities. Both sizes are available in tool steel or stainless steel.

The installation should be planned by a qualified structural

engineer. Each installation is unique, and this booklet is meant
to serve only as an overview for installation of the RL1800
Series Weigh Modules.
