PR-14 series RTD probe with miniature aluminum protection head and screw-on cap with chain includes PT100 Ω platinum RTD element or PT1000 RTD element, 1/2" NPT mounting threads and sheath of 316 stainless steel. When properly sized, these can go directly into a thermowell. All probes include a screw terminal block for easy connection of insulated copper extension wire. Replacement probes (without head assembly) are available as well as a "spring-loaded" option which allows for the probe to bottom out in a thermowell for quicker and more accurate response. These are ideal for use in vessels, tanks and similar structures where temperature measurements are needed.
Features:
- Mini aluminum protection head for areas where space is limited
- Protection head lid is chained so that lid stays with assembly
- Extreme temperature range: -200 to 600°C (-328 to 1112°F)
- Class "A" accuracy* conforming to IEC 60751
- Choice of PT100 Ω
- Standard probe lengths of 9 inches
- 3-wire Pt100 RTD sensor with a 1/4 inch sheath diameter
