A 1dobeginiftable1. nelds [j]. asstring = \.) digital voltmeter circuit above 2.1 have been identified as a digital voltage meter range 2.O00V,ed hardy clothing, the measuring circuit output voltage U0 direct input to the input side of Figure 3. 3 1T measuring circuit design method the design parameters should be According to Uo = ~ -6 -. · AR to test ll0 consider,ugg stivali, Ptl00 temperature coefficient is positive,stivali ugg, that is, as the temperature rises and its resistance is larger. Figure 3 shows the digital circuit tester. Ptl00 the temperature range of the sensor for a 100 ~ 300 ~ C,ugg milano, that is Vin should be less than 2.O00V,ugg italia, in the digital circuit part is ICL7106A / D converter, when the range time for the 2.O00V, VREF should be 1.O00V. in the process temperature should be made Uo <2.O00V, so V Ⅱ can be adjusted according to actual situation is less than 1V. reference voltage v Ⅱ through the external circuit to obtain a more stable reference voltage v Ⅱ (35 feet) of the resistor (1OkQ series 15kQ) and stability control Dz, 15kQ by adjusting the potentiometer, the voltage to 2.2V Dz's partial pressure to obtain V Ⅱ. 4 Rt debug method the sensor placed in O ~ C solution of ice on the ice, the voltage regulator device fuP., the voltage meter Display value of 0.00; then placed in maximum temperature Rt constant temperature oil bath, adjust RPz so close to the upper limit temperature indication, and then fine-tune the number of potential road section 15 of the potentiometer, the accuracy of the displayed value is equal to the upper limit temperature value can be repeated several times to adjust. 5 practical pharmaceutical use this tester to test the surface temperature of the motor and with a standard thermometer (indexing is 0.1oC) compared to measurements in Table 1. Table 1 Measurement Test results of the number of l23 temperature (℃) 21.2021.5O21.40 standard thermometer temperature (℃) 21.1521.4221.32 error (%) 0.240.370.38 we can see from the above data, the use of this test Measuring the surface temperature of the motor the maximum error is 0.38%; this tester can be used a surface temperature of the testing and monitoring. 6 Conclusion With this tester the surface temperature of the surface temperature, high precision, small error and small , light weight, thin, soft sensors, and surface-phase fully fit, so the enterprise can improve productivity, ensure the equipment is fully operational, with good prospects for development.
