Literature Code PI.8036.1108 Process Instruments www.thermo.com/bulk-handling Thermo Scientific Ramsey Digital C-Level Controls This device is a low-cost, microprocessorbased control with digital readout. Its 16-digit alphanumeric display and membrane keyboard make set-up and calibration very easy. This highly flexible device will display weights in tons, pounds, grams, kilograms or percent. It can act as a simple batching control or as a weight transmitter with optional 4-20 mA or RS-485 serial communications. The system is available as a compact panel mount DIN version (Model DCL-100) or as a field mount NEMA-4X version (Model DCLF-100). Thermo Scientific Ramsey GZ-1 Strain Sensor Filling any vessel or bin supported by metal members causes the supports to deform due to the addition of material weight. Although this deformation is so slight that it cannot be seen, it can be accurately measured by the sensor. When installed, this stainless steel sensor actually becomes part of the support structure. Its unique shape and full wheatstone bridge design cancel most of the effects caused by temperature changes. Once the sensor is electrically excited, a change in the strain of a support member will result in a proportional change to the output signal of the sensor. The sensor has been successfully applied to I-beam, angle, pipe and skirted silo supports in over 100,000 installations. It comes complete with a special installation tool (U.S. patent no. 4738135) for easy installation. Tank Weighing Assemblies Compression tank weighing assemblies are available as an option for the Ramsey C-Level system. Tank weighing assemblies used in conjunction with the Ramsey DCL and DCLF controllers can achieve accuracies of 0.5% or better. They are self-checking and available in sizes from 1,000 pounds to 300,000 pounds, eliminating the need for stay rod assemblies. They feature 150% compression overload protection and can withstand 100% of their rated capacity in any direction with a UBC-88 rating for seismic zones one through four. Tension S-Beam Load Cells When weighing for level indication in hanging bins, such as day bins or ingredient bins, the Ramsey C-Level system utilizes tension load cells. They are available in capacities of 200 pounds to 20,000 pounds and can provide accuracies of 0.5% or better. The load cells are rated for 150% overload and have normal deflections of 0.015 inches to 0.025 inches at full capacity.
