For the alternate wiring arrangement, change “-1” to “-2” in the model number, no additional cost.
For a probe length not listed up to 24", change the stem length in the model number to the required stem length (Example: 1250 = 12½") and
use the price of the next longer sensor.
Ordering Example: PR-31SL-3-100-A-0400-M12-1, 4-wire 100 Ω Class A RTD sensor with M12 connector wired in the “-1” configuration
(see figure) that spring loads into a thermowell with a 0.260" diameter bore and a stem length of 4" or less.
