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 DS18B20 1-Wire temperature sensor embedded into the probe. In manufacturing the temperature probe a special process is used which insures the internal sensor is thermally coupled to the steel tube wall; this helps insure rapid thermal response to changing conditions.
The probe is designed to make the installation process as fast and error free as possible. It is the first 1-Wire probe to automatically identify whether external power is being supplied to the VDD pin and then configure the sensor appropriately. Furthermore, it is terminated with a RJ12 plug which commonly makes installation much easier.
The probe is directly compatible with all Embedded Data Systems and Maxim 1-Wire bus masters, as well as free TMEX drivers. For complete documentation on the embedded DS18B20 sensor, please refer to the manufacturer’s DS18B20 spec sheet.

The RJ12 pin outs are as follows:
- Pin 3: 1-Wire Signal, Blue
- Pin 4: Common (GND), White
- Pin 6: Ext. Power (VDD), Orange, (connection not required)
Our standard OW-TEMP-B3-12RA sensor has a 3 inch long steel probe, 12 foot long cable and a RJ12 plug. With minimum orders we can manufacture the temperature probe to a variety of specifications, including length of the steel probe, length of cable, with / without RJ12 plugs, etc. Please contact us for a custom quote.
