The Model 729A Flexible Probe is a general purpose probe designed to cover most applications where non-rigid probes are required or desired. Typical applications of the flexible probe are in large tanks where rigid probes are prohibitive or where overhead room precludes the use of rigid probes.

The standard conductor on the Model 729A is made of 316 stainless steel multi-strand cable that is offered as:
(a) A bare cable for use in dry products,
(b) Teflon insulated cable,
(c) Polyethylene insulated cable.

Any of these are available with or without a lower end termination fitting. This termination fitting  is constructed of stainless steel or of non-metallic material that is the same as the insulating
material on the cable. The stainless steel termination fitting should only be used in dry or  granular products or in non-conductive low dielectric liquid products whereas the non-metallic
termination fitting is to be used only in liquid products, either conductive or non-conductive. The Model 729A Flexible Probe can be "tailored" to meet nearly any specific application
by the addition of options that are readily available. These options include:

• Weights and turnbuckle for holding the probe down.
• An "eye" (termination) for tying the probe down to the bottom of the vessel when required (liquid products only).
• Flanges either welded or screwed onto the probe gland.
• Sheaths - flexible or rigid - as required.

The standard process connection for the Model 729A is a 1" NPT male thread.
