TRAL-A/V/VMT

Absolute vibration transmitter with dual alarm thresholds

Compact solution for vibration monitoring.

The TRAL-A/V/VMT transmitter measures absolute bearing vibration of any rotating machine by connection to a transducer (accelerometer, velocimeter or velomitor). It can interface directly with PLC or DCS acquisition systems, providing a 4÷20 mA analog signal and two alarm contacts.

Processes and converts the signal from the transducer, providing an output proportional to the measured quantity. Designed for industrial applications, it integrates protection and diagnostic functions in one compact unit.

  • Built-in protection: ensures machine safety through configurable alarm thresholds.

  • Diagnostic functions: enables real-time monitoring of operating conditions.

  • Compact design: combines multiple features in a single unit, reducing space requirements and installation complexity.

  • Industrial reliability: designed to operate in harsh environments and ensure business continuity.

Product complies with European standards
CSA-UL Certification

Features

TRAL-A/V/VMT Main Features

  • Two relays with configurable alarm contacts.

  • Signal LEDs for alarm activation.

  • Safe area installation with possibility of connection to intrinsically safe transducers via certified barriers.

  • Dedicated terminal blocks for connecting power supply, inputs and outputs.

  • BNC port for quick connection to vibration analyzer.

Installation and safety

TRAL-A/V can be installed in safe area and connected to transducers in classified area via certified barriers. Dedicated terminal blocks allow simple and tidy wiring for power supply, input/output signals and diagnostics.

Alarms

  • 2 adjustable thresholds between 10% and 100% of the measurement range by graduated trimmers.

  • Delay to tripping adjustable by trimmer (0.2÷5 sec.).

  • 2 LED signaling intervention rel.
