Bently Nevada 1900/27-02-00 Single‑channel locally mounted vibration monitor

FAQ

Q1: What is the primary purpose of the 1900/27‑02‑00 monitor?
A1: It monitors vibration via a single transducer input, processes the signal into velocity units, provides local status indication (OK/Alert/Danger), and offers a 4‑20 mA output for trending.

Q2: What kind of transducers can be used with this device?
A2: It supports compatible accelerometers rated at around 100 mV/g and up to 20 g peak input.

Q3: What measurement range does it support?
A3: The full‑scale velocity reading is approximately 50.8 mm/s (2 in/s) zero‑to‑peak, with monitoring accuracy up to ~4 kHz.

Q4: What are the physical dimensions and weight of the unit?
A4: It is typically about 132 mm × 132 mm × 71.1 mm in size and weighs around 0.40 kg (0.85 lb).

Q5: What is the operating temperature and environmental specification?
A5: The unit operates from –20 °C to +70 °C, stores from –30 °C to +90 °C, and supports up to 95 % non‑condensing humidity.

Q6: What outputs and signals does the monitor provide?
A6: It offers a buffered transducer output (19.7 mV/mm/s), a 4‑20 mA output for velocity, and dry relays for Alert/Danger statuses.

Q7: Is the monitor suited for integration into control or automation systems?
A7: Yes — with its 4‑20 mA output, galvanic isolation, and buffered output, it can interface with DCS/PLC systems for trending and protection.

Q8: What makes the “‑02‑00” variant different from other 1900/27 versions?
A8: The “‑02‑00” suffix denotes specific internal configuration and options (such as power supply type or relay settings) differing from the standard “‑01‑00” variant.
