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 0.1°C 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. . .

Read Temperature With One Digital Output and One Digital Input : 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.

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

Two-Chip Digital Thermometer Delivers 0.4°C Accuracy: 07/08/02 Electronic Design - Ideas for Design / An LED digital thermometer with an operating range between 0°C and 150°C, 1°C resolution, and ±0.4°C accuracy is presented in the figure. This design is based on the PIC16F872.
