Overview
Bently Nevada 1800/15 (PN: 1800/15-12-90-02-00) is a loop-powered relative vibration transmitter. It converts proximity probe signals directly into a 4–20 mA output, eliminating the need for rack-based monitoring.
This transmitter combines a Proximitor sensor and signal conditioner in a compact DIN-rail package, allowing direct connection to PLC or DCS inputs for Balance-of-Plant machinery protection. Its rugged construction ensures long-term reliability in harsh industrial environments.

Key Features
-
Cost-Effective Protection: Ideal for secondary machines without a full 3500 rack.
-
Seamless Diagnostics: Buffered output allows waveform/FFT analysis.
-
Environmental Resilience: Wide temperature range and robust electrical isolation.
-
Fault Detection Intelligence: Detects sensor loop failure; current drops below 4 mA if a probe wire breaks.
Typical Applications
-
Centrifugal Pumps – shaft unbalance/misalignment detection
-
Industrial Fans & Blowers – vibration protection for motors and gearboxes
-
Small Turbines – auxiliary steam turbine vibration feedback
-
Air Compressors – shaft-to-bearing clearance monitoring
FAQ
Q1: Can I use a 5-meter cable with this -90 version?
A1: No. The 1800/15-12-90-02-00 is calibrated for 9.0 meters. Using the wrong length causes inaccurate readings.
Q2: Does this transmitter require an external 3300 XL Proximitor?
A2: No. The 1800/15 includes a built-in Proximitor; connect the probe extension cable directly to the transmitter.
Q3: What happens if loop power is lost?
A3: Output drops to 0 mA, allowing the DCS to trigger a Channel Fault alarm.
Q4: How do I set the probe gap?
A4: Adjust the probe until the Buffered Output reads approx. -10 VDC, centering the shaft in the linear range.
