CTM1 & CTM3 Transducers

The CTM1 was produced for a short time in the late 1990s. It used a stainless steel shaft and bottom plate with a black plastic multi-sensor module attached. The stainless shaft jack nut used 3 stainless screws for a more secure lock.

This was a valve model. The retaining clevis pin entered through the top valve sleeve.

An optional long-stem conversion kit #33-170 was available to lengthen the shaft by about 2.5" to create the CTM3.

The fairing block #33-169 for both variants is no longer available.
