The OW-TEMP-Sx-xx temperature probe is designed for wide temperature range applications requiring sensor submersion and/or excellent chemical resistant properties. The probe is resistant to acids, alkalis, ketones, esters, aliphatics, aromatics, and outdoor exposure. It is constructed of 304 Stainless Steel making it both durable and water resistant. The cable used is constructed of TPE based materials for both the outer jacket and inner conductor insulation. It is particularly suited for harsh environments, and offers excellent resistance to high and low temperatures, oil, gasoline, and sunlight exposure. All of this results in a robust sensor which can be submerged beyond the top of the steel probe.
The sensor is equipped with a DS18S20 1-Wire temperature sensor embedded into the probe. In manufacturing the temperature probe a special process is used which ensures the internal sensor is thermally coupled to the steel tube wall; this helps ensure rapid thermal response to changing conditions.
The probe is directly compatible with all Embedded Data Systems and Maxim 1-Wire bus masters, as well as our OneSix server software and the freely available TMEX drivers. For complete documentation on the embedded DS18S20 sensor, please refer to the manufacturer’s DS18S20 spec sheet.
