This unique thermocouple is easy to adjust to ANY immersion depth into thermowells (but NOTE: this probe cannot be immersed in liquids). Adjustable depth eliminates the need to stock a variety of fixed depth immersion probes. The locking cap can be positioned anywhere along the flexible armor and obtains its locking force from a unique spring- action catch. The welded stainless steel tipped probe is held against the bottom of the well by compression of the armor.

Two styles are available. Style ADF has a unique locking fitting that mounts permanently to your equipment. The quick release action of the locking fitting allows fast installation and removal of the probe.

Style ADR has a removable locking fitting and requires a BTA adapter. This style is ideal for installations where the mounting surface is under a layer of insulation, or where the locking cap must be removable.
