The PR-31 series RTD temperature sensors feature a high temperature connector for application environments of up to
260°C (500°F). The new PR-31 series is contructed with our mineral insulated cable to offer the option of bending the probe in the field. The suggested bend radiusis 2x the probe diameter.
The PR-31 series are ideal temperature probes for the automation industry, food and beverage, chemical and industrial markets.
These RTD sensors can be used in any 2, 3 or 4-wire application by selecting one of the two available wiring arrangements (see the wiring diagrams below) and using only those wires needed for your connection. This allows for simplified, trouble free installation with any existing application. This also allows the PR-31 series sensor to be used for a wide variety of replacement applications since it can be connected as-is with just about any measurement or control equipment available when combined with a 4-pin female M12 connector extension or patch cable.
