1、 Product Introduction

This product is suitable for temperature measurement and control fields such as freezers, grain warehouses, storage tanks, telecommunications rooms, power rooms, cable trays, etc. Adopting digital temperature and glass sealed thermistor, it has heat resistance, cold resistance, and excellent stability.

2、 Product Features

1. The unique single wire interface method allows the 18B20S to achieve bidirectional communication between the microprocessor and the 18B20S with only one port wire when connected to the microprocessor.

2. The temperature measurement range is -55 ℃ to+125 ℃, with an inherent temperature measurement error of 1 ℃.

3. Support multi-point networking function, multiple 18B20S can be connected in parallel on a unique three wire, up to a maximum of 8 in parallel, to achieve multi-point temperature measurement. If the number is too large, it will cause the power supply voltage to be too low, resulting in unstable signal transmission.

4. Working power supply: 3.0~5.5V/DC (can be parasitic power supply for data lines)

5. No peripheral components are required during use

6. The measurement results are transmitted serially in the form of 9-12 digit words

7. The minimum diameter of stainless steel protective tube can reach 4.5mm

2. Using brass and stainless steel probes, it has fast thermal conductivity and higher sensitivity.

3. Using corrosion-resistant wires, it can be used for a long time in harsh environments.

4. Waterproof rating: After waterproof packaging, mechanical grooves are used, and the waterproof rating standard is higher than IP68

5. Humidity sensitivity level: 1A level

6. Suitable for: freezer, grain warehouse, storage tank, telecommunications room, power room, etc.

7. Customization of size specifications and parameters is supported. Please feel free to consult customer service.
