Model ER4210 is a retractable, flush-mount, electrical resistance probe ideally suited for applications where the probe element needs to be flush with the wall of the pipe. A specially designed packing gland is used with the probe for insertion to or retraction from a pressurized system without a process shutdown. Standard packing material in the packing gland is Teflon®, however, Grafoil® packing can be provided for high temperature applications. The probe is designed to mount into a 1 1/2" piping system, but can easily be adapted to fit larger requirements. The probe consists of an insertion rod with an element, a hermetically sealed connector welded in place, and a packing gland with a 1" to 1 1/2" swage nipple. The insertion length (I.L.) is calculated to the end of the element. Probe length can be specified by the customer. For standard probes, the maximum length is given in the chart below. Several standard elements are available to meet your specific needs.
