What differentiates the MTN/8006 from a simple 4-20 mA transmitter?

It is a complete converter that powers the piezoelectric sensor and integrates the signal, allowing the use of high-quality accelerometers instead of basic transmitters.

How is the output range selected (Speed vs Acceleration)?

It is defined when ordering the equipment: the MTN/8006 processes speed (mm/s) and the MTN/8006g processes acceleration (g) RMS.

What cable length does it support between the sensor and the converter?

Thanks to IEPE technology, it allows runs of up to several hundred meters of shielded cable without appreciable signal loss.

Monitran MTN/8006 Vibration Signal Converter

Manufacturer: Monitran
Category: Signal converters, INSTRUMENTATION

Monitoring the mechanical health of rotating machinery often requires integrating complex vibration sensors into industrial control systems that operate under current-loop standards. The MTN/8006 acts as the critical bridge between a standard accelerometer and the plant control infrastructure, converting the analog acceleration signal into a 4-20 mA output directly proportional to the RMS speed.

This module, designed for simplified mounting on a universal DIN rail, optimizes predictive maintenance by enabling direct vibration severity readings without the need for expensive analytical instrumentation or specialized training. Its compact design and screw terminals facilitate organized installation in electrical panels, providing continuous monitoring for bearing failures, imbalances, and misalignments in critical pumps, fans, and motors.

Thanks to its configurable filtering (with a standard -3dB cutoff at 1 kHz), the MTN/8006 ensures that the signal transmitted to the PLC is free of irrelevant high-frequency noise, focusing the diagnostics on the spectrum where most destructive mechanical failures occur. It is the ultimate tool for digitizing vibration monitoring with minimal investment.

Technical Frequently Asked Questions

1. Is it possible to adjust the speed measurement range on the MTN/8006?
Yes. Although the module is supplied factory calibrated, Monitran offers different scale settings so that the 4-20 mA range exactly matches the expected vibration severity (e.g., 0-10 mm/s or 0-25 mm/s), ensuring maximum resolution in the control system.

2. What type of sensors are compatible with the converter input?
The MTN/8006 is designed to accept standard accelerometer inputs (typically 100mV/g). It provides the necessary constant current power supply for the sensor and is compatible with the vast majority of IEPE piezoelectric transducers on the market.

3. Can this module be used to monitor temperature?
For temperature monitoring, the specific model MTN/8006TC must be used. However, both modules share the same DIN rail format, allowing them to be installed in parallel to obtain dual monitoring (vibration and temperature) of the same asset.
