The Crouse-Hinds series MTL TP-Pipe surge protection device is a unique unit providing a level of protection for field-mounted transmitters that is far in excess of the optional transient protection facilities available from the transmitter manufacturers – without involving any additional wiring, conduit modifications or other expensive extras.
The TP-Pipe protection network consists of high-power, solid-state electronics and a gas-filled discharge tube capable of diverting 20kA impulses. The whole unit is encased in an ANSI 316 stainless steel housing, threaded for the common conduit entries used on process transmitters. Versions are available for 1/2” NPT, 20mm ISO, and G 1/2” (BSP 1/2 inch) threaded entries.
For hazardous-area use, approvals for both intrinsically safe and flameproof (explosionproof) operation are available in all gas groups and apparatus temperature classifications up to T4.
