Model LP6100

Linear Polarization Resistance Probe
Fixed Length with Flange & 3-Electrode Endcap

View PDF version


Model LP6100 is a fixed-length, flange-mounted, linear polarization resistance probe. The probe is ideally suited for use in high pressure and/or hazardous applications where threaded fittings are not available or not recommended. Process shutdown or process isolation is required for installation and inspection. The probe assembly consists of an insertion rod with a three-electrode endcap, a hermetically sealed connector, and a flange (as specified by customer), which are all welded in place. Insertion length (I.L.) is calculated to the end of the electrodes and, in this case, is based on a 1" total flange thickness. Customers can specify any length required. For standard probes, the maximum insertion length is given in the chart below. Several standard electrodes are available to meet your specific needs. Electrodes are ordered separately.
