Quartz crystal based remote thermometer features direct Celsius readout: 03/17/05 EDN Design Ideas / (added 5/05)
Although quartz crystals have served as temperature sensors, designers haven't taken advantage of the technology because few manufacturers offer the sensors as standard products (references 1
and 2). In contrast to conventional resistanceor semiconductor-based sensors, a quartz-based sensor provides inherently digital-signal conditioning, good stability, and a direct digital ou... |

use an ADT7461 single-channel temperature monitor, an ADG708 low-voltage, low-leakage CMOS 8-to-1 multiplexer, and three standard 2N3906 pnp transistors to measure the temperatures of three
separate remote thermal zones (Figure 1). Multiplexers have an inherent-resistance on-resistance; the channel matching and flatness of this resistance normally results in a varying temperature

Square Root Function Improves Thermostat: 09/30/99 EDN-Design Ideas / (circuit design added 7/06) Perhaps the most
elementary rule of control-loop design theory is that feedback-loop performance is fundamentally linked to the careful choice—and stability—of loop gain. Insufficient loop gain leads to poor
setpoint accuracy. Too much gain can induce feedback instabilities, such as overshoot, ringing, and, ultimately, oscillation. Therefore, the greater the accuracy you expect from a control
system, the more critical maintaining near-optimal loop gain becomes. |
