A variety of plant, process, and instrumentation engineers, along with systems integrators, regularly face the difficult task of shopping for signal conditioners. Their goal is to obtain the highest quality conditioner for the lowest possible price. Sound simple enough? Well, it isn't. Few of the decisions that must be made are of the black and white variety. Most involve various shades of gray. The problem is, the selection of the wrong shade can result in the purchase of inadequate equipment, or equipment that will quickly become obsolete.
Pre-purchase system planning that includes a clear definition of the system requirements is the first step in the selection process. As a minimum, you should determine sensor input, type of output, isolation needs, power requirements, physical dimensions, and acceptable performance criteria.
