For longer sheath length, change “-6” in model to desired length in inches for additional cost when longer than 8". For Silicone Rubber
insulated cable, change “-P”, “-T” or “-G” to “-S” in the model number and use PFA pricing. For longer cable lengths, change “-3” to desired
length in feet for additional cost for PVC, for PFA or Silicone Rubber and for fiberglass. For shielding on PVC, PFA or Fiberglass insulated
cables, change “P”, “T” or “G” to “PS”, “TS” or “GS” for additional cost. Mounting threads also available in
the same price.

For longer sheath length, change “-150” in model number to desired length in millimeters for additional cost to the price when longer than
200 mm. For Silicone Rubber insulated cable, change “-P”, “-T” or “-G” to “-S” in the model number and use PFA pricing. For longer cable
lengths, change “-1” to desired length in meters for additional cost per meter for PVC, for PFA or Silicone Rubber and for fiberglass. For
shielding on PVC, PFA or Fiberglass insulated cables, change “P”, “T” or “G” to “PS”, “TS” or “GS” for additional cost per meter to the price.
Mounting threads also available in M8x1 and M10x1 at the same price (Note: M6 threads not available on 6 mm Dia probes).
3 mm diameter sensors without threaded fittings and with “P”, “PS”, “TS”, “GS” and “S” cables include a transition fitting at the end of the sheath.
