Product Description

Its core advantage lies in true digital output: utilizing the unique "1-Wire" protocol, it transmits on-site temperature directly as a digital signal, significantly enhancing system noise immunity, making it particularly suitable for industrial settings with complex electrical environments. Each DS18B20 chip has a globally unique 64-bit serial number, supporting the connection of multiple sensors on the same bus, facilitating the creation of distributed temperature measurement networks.

3. Digital "1-Wire Bus," Strong Noise Immunity: 1-Wire digital interface. Far superior noise immunity for long-distance transmission compared to analog sensors. Simplified wiring (only one data line needed).Simplifies system cabling, reducing installation costs. Ideal for multi-node, long-distance temperature measurement networks.
4. Globally Unique Address, Easy Networking: Each sensor chip has a unique 64-bit serial number for precise identification by the host controller.Dozens of sensors can be easily connected on a single bus, facilitating the construction of large-scale distributed temperature measurement systems.
5. Highly Customizable, Flexible Adaptation: Probe size, cable material/length, output wiring configuration, and termination method can all be customized per request.Perfectly adapts to your specific installation space, environmental requirements, and interface standards, eliminating the need for secondary processing.



1. Probe Size: Diameter (D) x Length (L), e.g., 6mm x 30mm or 6mm x 50mm. Non-standard sizes are supported.
2. Cable Requirements:
* Material: PVC (general purpose), Silicone Rubber (flexible, high/low temp resistant)
* Length: Standard lengths negotiable, can be customized per meter.
* Wire Gauge: e.g., AWG22, AWG24, etc., selected based on current and mechanical strength needs.
3. Electrical Interface:
* Wiring Configuration: Choose 3-wire (independent power supply, stable and reliable) or 2-wire (parasitic power, saves one wire).
* Termination: Tinned wires (for terminal blocks) or specify connector model (e.g., JST PH2.0, Molex 51021, etc.).
4. Special Environmental Needs: Whether enhanced waterproofing (higher IP rating), acid resistance, alkali resistance, or
corrosion resistance treatment is required.
