LMl35 precision temperature measurement circuit

Published:2011/3/21 1:13:00 Author:Joan | Keyword: precision , temperature measurement

LMl35 series has equipped with outside correct terminal, which can easily correct measurement error and effectively eliminate the error caused by manufacturing process by simple correction method. As shown in Figure 4, when the temperature is 25 ℃, the adjustment potentiometer Rw changes the calibration terminal bias, until the sensor output voltage turns to 2.982V measured by a digital voltmeter in 20V output range. After calibration, the circuit's measurement error is less than 1 ℃ within the 0 to100C ℃ range.   (View)

LM135 Ni-Cd battery fast charging circuit

Published:2011/3/21 0:52:00 Author:Joan | Keyword: Ni-Cd battery, fast charging

The figure is a safe and reliable Ni-Cd battery fast charging circuit. It detects the completion of battery chargeusing Ni-Cd battery case temperature change. In general, it has been already charge 80% of rated capacity when the rechargeable battery temperature rises to 5 ℃. ST1 is used to detect the ambient temperature, ST2 thermal coupled the rechargeable battery are used to detect the battery temperature. The offset terminal of the temperature sensor adjust ST1 output voltage 50mV higher than that of ST2. When the battery temperature exceeds 5 ℃ of the ambient temperature, the comparator LM308 output goes low, LM317change from constant current source state to the voltage source state, the output voltage is only about 2V, Power supply continues to charge the battery only through the R by 50mA small current. The method can save time and will not overcharge.   (View)
