Thermocouple Probes
with One Inch of Bare Leads
A8 Series
Probes can be supplied spring loaded or with fixed mounted fittings. All fittings are 304 stainless steel with 1/2 inch NPT for mounting into: walls, connector heads, or thermowells. The (SL - spring loaded) units allow up to 3/4 inch of travel. The (W - welded) units have the 1/2 inch NPT fitting brazed to the probe. All replacement units are supplied with one inch of bare leads.
- Duplex junctions units are available on all models except 1/16 inch diameter units. Contact factory for more information.
NOTES:
- Keep in mind that either Spring-Loaded (SL) or Welded (W) bushings utilize approximately two inches of the sheath length. Please account for this when specifying length.
- PFA Teflon® encapsulation - good to 450°F, can be added to any probe.
Thermocouple calibration type N is available in all sizes.
