Series 10 are resistance temperature detectors. We can manufacture these using durable epoxy potted elements (400°F) with Teflon insulated leadwires in a wide range of sheath diameters. For higher temperatures (up to 1000°F) we offer a similarly versatile construction utilizing fiberglass insulated leads and higher temperature potting/backfilling materials. Finally we also offer RTD's manufactured from metal clad MgO insulated material. These are extreamly durable and offer the widest temperature ranges (-400°F to 1200°F) but are available in a more limited range of sheath diameters and lengths. We offer styles with a quick connect plug or jack (Series 10Q), lead wire (Series 10E), a transition to lead wire (Series 10L), a terminal head with optional mounting fitting (Series 10C), a terminal head with nipple-union-nipple (Series 10U), a bayonet cap and spring (Series 10B), or a on-site cuttable (Series 10T) that can be cut to length as needed.
