Product Introduction
The Bently Nevada 1701/06 (Part Number 141377-01) is a General Purpose Vibration Monitor from the 1700 series. It is a compact, single‑slot monitor designed for continuous, online protection of non‑critical or general‑purpose rotating machinery. The module accepts input from a single seismic accelerometer or velocity transducer (IEPE type) and provides a 4‑20 mA output proportional to overall vibration level (RMS or peak). It also includes two programmable alarm relays (Alert and Danger) for local annunciation or machine shutdown. The 1701/06 is typically mounted in a 1700 series rack (e.g., 1701/03) or can be used as a stand‑alone panel‑mount monitor with an optional housing. This variant (141377-01) includes a standard 0–1 in/s (0–25.4 mm/s) velocity range, 4‑20 mA output, and dual relay outputs.

Application Scenarios
Non‑Critical Pumps and Fans – Continuous vibration monitoring on centrifugal pumps, axial fans, and blowers in HVAC, water treatment, and light industrial plants, providing early warning of imbalance or bearing wear.
Small Electric Motors – Installed on motors up to 500 HP to detect misalignment, looseness, or rotor bar problems, triggering alarms before failure.
Packaged Compressors – Used on reciprocating or screw compressors in manufacturing facilities to monitor casing vibration and prevent costly downtime.
Retrofit of Legacy Systems – Replaces outdated analog vibration switches (e.g., 1‑out‑of‑2) with a programmable monitor that offers 4‑20 mA trending and adjustable setpoints.
Stand‑Alone Machine Protection – Can be used without a full rack by mounting the module in a small enclosure, ideal for protecting isolated machinery in remote locations or on mobile equipment.
