Precision Thermometer Linearizes, Digitally Calibrates Platinum RTDs:  05/29/00 Electronic Design - Ideas for Design / Among temperature transducers, the platinum resistance temperature detector (PRTD) is generally accepted as the “gold standard.” PRTDs are available with interchangeability accuracies as tight as 0.1C over operational ranges extending from. . .
Precision Thermostat Uses TBH And AC Feed-Forward Compensation:  03/19/01 Electronic Design - Ideas for Design / Precision temperature control with relatively high-power heaters driven directly from unregulated "120-V" ac lines is an efficient, inexpensive way to manage large thermal loads. A number of annoying complications can render this straightforward. . .
:  03/04/02 Electronic Design - Ideas for Design /Before the MAX6629/30/31/32 series of temperature sensors were available, all digital-output temperature sensors were I2C (alternatively called SMBus) sensors that had to be written to for addressing, before they were read. Prior SPI...  
Take Back Half: A Novel Integrating Temperature-Control Algorithm:  12/04/00 Electronic Design - Ideas for Design / According to Linear Technology’s Jim Williams, “The unfortunate relationship between servo systems and oscillators is very apparent in thermal control systems.” (Linear Applications Handbook, 1990). High-performance temperature control is. . .
Take-Back-Half HVAC Thermostat Is Precise And Energy-Efficient:  07/09/01 Electronic Design - Ideas for Design / Implementing tight control of environmental temperature is essential in many critical areas. For instance, it's necessary when research laboratories house sensitive instrumentation and for manufacturing facilities involved in high-precision. . .
Temperature-Compensated LCD Bias Supply Uses A Single Control IC:  06/08/98 Electronic Design - Ideas for Design / Many applications require a simple method for getting multiple outputs from the power supply. One way to achieve this goal is by using charge pumps. The schematic shown in Figure 1 is an LCD bias. . .
Thermocouple Interfaces to Serial Port:  11/09/95 EDN-Design Ideas
