Bently Nevada 1900/65 General Purpose Equipment Monitor

Description

The Bently Nevada 1900/65 is a flexible, cost-effective general-purpose equipment monitor designed to continuously monitor and protect essential and balance-of-plant equipment assets. The 1900/65 accepts eight total input channels (four vibration and four temperature) and processes them into up to 20 different user-selected measurement variables. It features six individually programmable relay outputs, four 4-20 mA proportional outputs, and buffered output facilities for direct connection to portable diagnostic instruments. Configurable via Microsoft Windows-based software, the system supports an optional display module that can be installed directly on the monitor or located up to 75 meters (250 feet) away. It is suitable for applications across oil & gas, power generation, water treatment, pulp & paper, manufacturing, mining, and cement industries.
