Model LP4100 is a retractable, linear polarization resistance probe
commonly used in field and plant applications. A specially designed packing gland is used
with the probe for insertion into or retraction from a pressurized system without a
process shutdown. The packing gland is designed to mount easily on a 1" piping
system, but it can be modified for your specific mounting requirements. The probe assembly
consists of a packing gland, an insertion rod with a hermetically sealed three-electrode
endcap, and a five-pin military connector mounted in place. A safety chain is also
provided to prevent blowout. Standard packing material in the packing gland is Teflon®,
however, grafoil packing can be provided for high temperature applications. The insertion
length (I.L.) is calculated to the end of the electrode and can be specified by the
customer. For standard probes, the maximum insertion length is given in the chart below.
This maximum I.L. is based on the length of a carbon steel electrode. Electrode
lengths may vary depending on the alloy. Electrodes are ordered separately.
