Tempco RTD00703 3-Wire Probe
This Tempco RTD00703 is a Pt100 temperature probe with a 3-wire configuration and a straight 0.25 in stem. It suits technicians and engineers who need reliable temperature sensing in HVAC, food processing, pharmaceutical or packaging environments. The probe operates from -18 °C to 200 °C and fits a 1/2 in MNPT process connection.
Check stem length and wiring before ordering
Verify that the 0.25 in straight stem reaches the measurement point in your duct, oven or vessel. Confirm your controller or transmitter accepts a 3-wire Pt100 input, as 2-wire or 4-wire devices are not compatible. Ensure the 1/2 in MNPT thread matches the existing fitting or that an appropriate adapter is available.
Fits 1/2 in MNPT ports and frees terminal wiring
The probe installs directly into a 1/2 in MNPT port without additional cable glands, since the cable material and length are not applicable and the connection is made at the terminal block. This arrangement frees up space around the process connection and simplifies wiring for PLC or DCS inputs. The transparent body allows visual inspection of the sensor element.

Questions about this item
Does the RTD00703 include a cable or terminal block, or must I supply them?
The probe connects via a terminal block; no cable is included.
When should I choose the 3-wire Pt100 version over a 2-wire alternative?
The 3-wire Pt100 compensates for lead resistance, giving tighter accuracy on long runs.
What does the 392 °F upper limit mean when the probe sits in an oven or duct?
It is the maximum continuous temperature the Pt100 element can withstand without drift.
