     This product is found by the Shanghai Industrial Co., Ltd. Bo (www.dwn.com.cn) and the Shanghai Institute of Geology and Mineral Resources Engineering Investigation cooperation, most of the Shanghai study geothermal wells (3013.45 meters deep) to heat the pilot survey is designed as detailed in news: http://www.dwn.com.../../news/8000/98.html

The sensors are commonly used in applications where temperature measurement:

Air-conditioning heat exchanger temperature wells, hydro-geological monitoring, measurement of water temperature distribution

SLST1 family of digital temperature sensor with the United States Dallas Semiconductor digital temperature sensor DS18B20, sensor package, stainless steel case, waterproof moisture. Specially designed stainless steel sensor housing, the wall thickness of only 0.15mm, a small store heat molding to metal pads and stainless steel wall DS18B20 full access, while using a high thermal conductivity potting sealant to ensure a temperature sensor high sensitivity, small temperature delay.
SLST1 temperature sensor support "bus line" interface (1-Wire), measurement temperature range of -55 ° C ~ +125 ° C, at -10 ~ +85 ° C range, accuracy ± 0.5 ° C. Field temperature using "bus line" of the digitally transmitted, which greatly improves the power system. Harsh environment of the site is suitable for temperature measurement. SLST1 digital temperature sensor has a unique number, temperature acquisition device through the numbers to identify the corresponding temperature sensor. Sensor lead length can be customized according to user needs, special sensor lead with 3 core wire, a length of 1 meter factory.


Typical Applications:

Air conditioning heat well temperature measurements, hydrogeologic monitoring, measuring water temperature distribution can also be used for:
1, 2 cold storage temperature monitoring, pharmaceutical GMP monitoring system 3, 4 telecommunications room monitoring beer production
5, building automation 6, 7 storage temperature monitoring, environmental monitoring, 8, 9 Temperature monitoring, air monitoring
Overall dimensions: sensor with stainless steel shell packages, use the icon, please note that the shaded area for the heat-sensitive sensor. A length of 25mm, 30mm two specifications, lead length can be customized, up to 100mm
