* Tolerances based on precision factory calibration and test equipment. Customers checking tolerances should allow for differences in test equipment of ±1°F.

Temperature settings outside the ranges indicated or to closer tolerances will be considered on special request.

CONFIGURATIONS

Standard 11041 (M1) probe packages are comprised of the following physical features, but many other variants are available. The standard material is

stainless steel, but nickel plated brass versions are available.

PLEASE NOTE: The orientation of the connector with respect to the package body is not controlled.

Probe Body Thread Sizes

Standard lengths are available in ½” increments from 1.5” to 6”.

Termination

Standard connector is a Sealtron B8002G-10SL-4P-F (or equivalent)

Standard wire leads are AWG #18 stranded wire with white or black Teflon*

insulation (per MIL-W-22759) (Teflon is a trademark of E. I. Dupont de Namers

and Co.)
