Description: The sensor is equipped with a DS18B20 1-Wire temperature sensor embedded into the probe with a 15metre cable and 3 wires at end. In manufacturing the temperature probe a special process is used which ensures the internal sensor is thermally coupled to the tube wall, this helps ensure rapid thermal response to changing conditions.

The DS18B20 digital converts the temperature at sensor for up to 12 bits (9 bits primary temperature measurement plus an overflow counter) or 0.0625 °C of resolution. It features an alarm function with non-volatile user-programmable upper and lower trigger points. Each sensor has a unique serial number and multiple sensors can share a single bus. The DS18B20 communicates over a 1-Wire® bus that by definition requires only one data line (and ground) for communication with a central microprocessor. It has an operating temperature range of -55 to +125 °C and is accurate to ±0.5 °C over the range of -10 to +85 °C. In addition, the DS18B20 can derive power directly from the data line ("parasite power"), eliminating the need for an external power supply.

Applications where this feature is useful include HVAC environmental controls, sensing temperature inside buildings, equipment or machinery  and process monitoring and control.

Submersible, rugged, wide temperature range probe suitable for use in harsh environments.
