MTL TP-AC range MTL TP-AC420 Safeguards electronic process transmitters against induced surges and transients from field cabling

MTL TP-AC range of surge protection devices uniquely provides a level of protection for AC powered, field -mounted transmitters that is far in excess of the optional transient protection facilities available from the transmitter manufacturers - and achieved without any additional wiring modifications or costly additions.

The TP protection network consists of high power, solid state electronics and a gas-filled discharge tube (GDT) capable of diverting 20kA impulses. The whole unit

is encased in ANSI 316 stainless steel housing, threaded for attachment in conduit entries used on process transmitters. Versions are available with ½” NPT and 

20mm ISO threaded entries.
