Thermometer code

All the preceding discussion has concerned continuous numerical data. Not all data is of this form, and we now discuss the encoding of nonnumerical data. Logical variables have one of two values that are encoded as zero and one. An example is the presence or absence (a yes or no) of a feature. Typically the presence (yes) is encoded as a 1 and the absence (no) as a 0. Categorical data should be encoded in some variation of a one-of-N code (N equals the number of categories) or a thermometer code. 

Thermometer codes allow you to establish a ranking among categories. Suppose there are three models of some product 222 the base model, the standard model, and the deluxe model. These would be encoded with three variables, the base model being given by 1,0,0, the standard model by 1,1,0, and the deluxe model by 1, 1,1. 

The design of mixing tanks is standardized DIN 28 130 [161, 506], ASME Code Section VIII. Internal fittings include baffles, coils, probes (e.g. thermometer, level indicators) and feed and drain pipes. All of these fittings can influence the stirring process. 

If state or local requirements are based on the 2001 FDA Food Code, wash, rinse, and sanitize food contact surfaces of sinks, tables, equipment, utensils, thermometers, carts, and equipment ... 

C. Adjust the portion of the code and the thermometer so that the coric fits tightly, the thermometer and the jar are coaxial, and the thermometer bulb is resting on the tottom of the jar. 

The most frequently encountered source of error when using liquid-in-glass thermometers is the misuse or complete neglect of the emergent-stem correction. This correction derives from the use of the thermometer with a portion of the stem exposed to a different temperature from that of calibration. A common example is the use of partial immersion of a thermometer calibrated for total immersion. For detailed information on this correction, see the American Society of Mechanical Engineers Power Test Codes Temperature Measurement. 

If for reasons of protection of the sensitive temperature-measuring element against corrosive atmosphere or excessive mechanical stress, the use of thermometer wells is prescribed, such wells should be designed and installed with the utmost care to avoid damage and the introduction of additional errors. The ASME Power Test Codes should be followed in this respect. The most important precautions in using a thermometer well are to keep the sensing element in...
