Product Overview

The Rosemount 3051S Transmitter is a high-performance pressure, flow, and level measurement device widely used in industrial applications. A critical component of this transmitter is its lightning protection terminal block, designed to safeguard sensitive electronics from electrical surges, including lightning strikes and power transients. This terminal block integrates seamlessly with the 3051S series, ensuring reliable operation in harsh environments such as oil & gas, chemical processing, and power generation.

Built with all-welded stainless steel (316L SST or Alloy C-276), the terminal block provides hermetic sealing to prevent moisture and corrosive gas ingress. It complies with IEC 62591 (WirelessHART®) and IEC 61508 (SIL3) standards, making it suitable for safety-critical applications. The lightning protection feature minimizes downtime by preventing electrical damage, ensuring long-term stability and accuracy.

Key Features

The Rosemount 3051S lightning protection terminal block incorporates multiple advanced features to enhance performance and durability:

Surge & Transient Protection: Built-in barriers protect against high-voltage spikes caused by lightning or power surges, reducing the risk of transmitter failure.
High Electrical Isolation: Prevents ground loops and ensures signal integrity, even in electrically noisy environments.
Corrosion-Resistant Materials: Options include 316L SST, Alloy C-276, and gold-plated terminals for aggressive chemical or marine applications.
Diagnostic Capabilities: The transmitter continuously monitors loop integrity, detecting issues such as open circuits or excessive resistance.
HART® 7 & WirelessHART® Support: Enables digital communication for remote configuration and diagnostics without interrupting the 4–20 mA signal.

Additionally, the terminal block supports NACE MR0175/ISO 15156 compliance, making it ideal for sour gas and high-corrosion environments. Its 15-year drift-free stability and 200:1 turndown ratio ensure precise measurements over extended periods.
