Accurate, reliable temperature control need, not be e x p e n s i v e By John W. Ritter, Test Engineer Sarco Company, Inc. Temperature regulation equipment for food processing should be simple to use and easy to maintain. It should be abso lutely reliable for the protection of the product—and inexpensive enough to use economically. The satisfaction of these multiple de mands is a matter of selecting controls that match the job, buying only the amount of control you need and no more. A very good solution to this problem is the specification of a Sarco Electric Indi cating Control. This type of control allows you a wide selection of ranges and adjust ment within those ranges for your exact operating conditions. The same unit can be used for control ling steam, water, or electricity and will regulate heating or cooling or both. For additional flexibility in controlling heating or cooling, various interval timers and other control devices can be incorpo rated with Sarco Electric Indicating Tem perature Regulators. Sarco Electric Indicating Temperature Regulators include large easy-to-read dials with both actual and set temperatures on one scale, g r a d u a t e d in regular, even increments.

TO PROVIDE TEMP CONTROL
The installed cost of Sarco Electric Indicating Temperature Controllers is low, and they are inexpensive to maintain. They provide the sensi tivity you need over the temperature range of your process. You get response to temperature changes of ± y 2 ° F . You change control setings simply by turning one knob. You get a continuous visual check on process temperature by reading both set and actual temperature on one large scale. Sarco Electric Indicating Temperature Controllers are available for temperatures from 90°F. to 650°F., in operating ranges from 100°F. to 400°F. In addition, they offer many switch sequence combinations, such as step-heating, heating and cooling, and temperature control with the operation of visual or sound signaling devices.

This rough sketch shows how the Sarco LSI Electric Indicating Temperature Control can be used to actuate valves or relays, control flow or provide temperature control for heat ing or cooling.
In addition to simplicity and reliability, the Sarco control can be quite easily main tained by the regular maintenance crew, and its installation is a simple and inex pensive job.
