TP-AC Range Data and Signal Surge Protection
Brand: MTL InstrumentsThe 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 threaded entries.
