Communications

Built‑in TIM: For Trendmaster® 2000 system connection

No Modbus/Ethernet (simple local monitor)

Core Functions

Single‑Channel Displacement Monitoring: Measures shaft vibration/runout via eddy‑current probe.

Dual Alarm Thresholds: Independent Alert (warning) and Danger (trip) with delay (0.1–30 s).

Local Indication: LCD display for real‑time value; LED status lights.

Sensor Diagnostics: Detects open/short circuit, fault, out‑of‑range.

Standalone or System Use: Local protection or integration with Trendmaster® 2000.

Compact & Low‑Cost: Ideal for basic monitoring points without multi‑parameter needs.

Applications

General Industry: Pumps, fans, blowers, small motors (shaft displacement monitoring).

Oil & Gas: Auxiliary equipment, non‑critical compressors.

Power: Cooling tower pumps, boiler fans, small turbines.

Retrofit Projects: Replaces old single‑channel monitors; easy field installation.

Usage & Maintenance

Installation: Wall‑mount; wire 3300XL probe to rear terminals; connect power.

Configuration: Set range, alarm thresholds via DIP switches or local buttons.

Maintenance: Annual wiring inspection; no routine calibration required.

Compatibility: Works exclusively with Bently Nevada 3300XL proximitor sensors.
