DS18B20 Temperature Sensor

A DS18B20 temperature sensor is a digital temperature sensor designed for temperature monitoring in industrial equipment, automation systems, water tanks, HVAC equipment, refrigeration systems, and other temperature-controlled applications. It uses a 1-Wire digital communication interface to connect with compatible controllers and monitoring systems.

EaseWise supplies DS18B20 temperature sensors for standard, industrial, and OEM applications. Available configurations include waterproof stainless steel probes, flexible cable options, aviation connectors, and threaded probe constructions. Probe diameter, cable length, connector, mounting method, and other specifications can be customized according to application requirements.

DS18B20 Temperature Sensor Configurations

Waterproof Stainless Steel Temperature Probe

The waterproof stainless steel probe is designed for liquid temperature measurement and general industrial monitoring. SS304 construction provides a durable probe housing for water tanks, HVAC systems, equipment, automation systems, and other applications requiring a sealed temperature probe.

DS18B20 Temperature Probe with Silicone Cable

Silicone cable provides greater flexibility and improved temperature resistance compared with standard PVC cable. It is suitable for equipment where the cable needs to bend or operate in a higher-temperature environment.

DS18B20 Temperature Sensor with Aviation Connector

An aviation connector provides a secure detachable connection for equipment and control systems. Connector type and cable length can be customized according to installation requirements.

Threaded DS18B20 Temperature Probe

Threaded probes provide secure installation in tanks, pipes, and industrial equipment. Metric and other thread configurations can be customized according to the application and mounting requirements.

How Does a DS18B20 Temperature Sensor Work?

The DS18B20 temperature sensor measures temperature and converts the measurement into a digital signal. It communicates temperature data to a compatible controller through a 1-Wire interface, allowing multiple devices to share the same communication bus with appropriate system configuration.

This digital output eliminates the need for a separate analog-to-digital conversion stage at the sensor interface and makes the DS18B20 suitable for equipment monitoring, automation, HVAC, water temperature measurement, and IoT temperature monitoring systems.
