Safeguards electronic process transmitters against induced surges and transients from field cabling
• Protects 2, 3 and 4 wire transmitters
• Easy and direct mounting — screws into spare conduit entry
• Intrinsically safe and flameproof to CENELEC standards
• Parallel connection avoids introduction of any resistance into loop
• ATEX approved • 10 year product warranty
The TP48 range of surge protection devices uniquely provide a level of protection for 2, 3 and 4 wire 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 TP48 range protection network consists of high-power, solidstate electronics and a gas-filled discharge tube capable of diverting 20kA impulses. The whole unit is encased in a 316 stainless steel housing, threaded for the common conduit entries used on process transmitters. Versions are available for 1/2” NPT, 20mm ISO, and G1/2” (BSP 1/2 inch) threaded entries.
