STP - Wide Range Temperature Probe

The STP temperature probe is designed for general-purpose, wide temperature range applications. It is constructed of 304 Stainless Steel, making it both durable and water resistant to 60 PSI. The STP has good chemical resistance properties to acids, alkalis, ketones, esters, aliphatics, aromatics, and outdoor exposure.

While the steel probe is waterproof to 60 PSI, the sensor should not be submerged above the steel probe as the sensor is not waterproof at the cable’s point of entry into the steel tube.

For applications requiring complete submersion, broader temperature ranges, or additional chemical resistance, please refer to our model RTP (rugged) temperature probe.

The STP temperature probe is available with either a DS18S20 or a DS18B20 1-Wire temperature sensor embedded into the probe.  The STP probe is manufactured using a special process that insures the internal sensor is thermally coupled to the steel tube wall; this helps insure rapid sensor response to changing conditions.

Our standard sensor is equipped with PVC CAT5 cable with stripped leads.  Pin outs are as follows:

• Common (GND): Blue / White
• 1-Wire Signal: Blue
• Ext. Power (Vdd): Orange

Please note that if you choose to operate the sensor in parasitically powered mode, you must connect the Vdd and GND lines together, per the DS18x20 specifications.  When ordered with the optional RJ11 plug, we take the extra steps necessary during the plug installation to properly configure the sensor for parasitically powered operation.

The STP temperature probes are directly compatible with all Embedded Data Systems and Dallas 1-Wire bus masters, our OneSix server software, and the freely available TMEX drivers.  For complete documentation on the embedded DS18x20 sensors, please refer to manufacturer’s spec sheets available at http://dalsemi.com/ .
