Triple Output Vibration Sensor MTN/1181
- Manufacturer: Monitran
- Category: Accelerometers and Vibration Sensors, Amplified, SENSORS
The transducer MTN/1181 It is an advanced industrial vibration sensor designed to provide comprehensive mechanical diagnostics from a single measurement point. Unlike conventional accelerometers, this device integrates complex signal conditioning electronics (Amp) that requires a continuous 15-24V DC power supply. This active architecture allows for the simultaneous delivery of three independent, processed signals, facilitating direct integration into PLCs, SCADA systems, and building management systems (BMS) without the need for external converter modules.
Technically, the sensor delivers a triaxial data stream at the functional (not geometric) level:
1. DC output (0-10V) proportional to RMS speed (standard range 0-25 mm/s), optimized in the 10 Hz to 1 kHz band. This signal is the industry standard for monitoring structural fatigue and the overall condition of the machine according to ISO 10816.
2. DC output (0-10V) proportional to the Acceleration Envelope (Envelope g) (range 0-10g), a critical demodulation technique for the early detection of metallic impacts, lubrication failures and bearing raceway defects.
3. AC Analog Acceleration Output (100mV/g), which provides the high-fidelity raw waveform, allowing analysts to perform detailed spectrum analysis (FFT) by connecting a handheld data collector directly to the sensor.
Housed in a robust encapsulation with an IP67 rating and a structural mass of 400 grams, the MTN/1181 guarantees the stability of the three signals in an operating thermal range of 0 to 90 °C, making it the ultimate solution for demanding CMS (Condition Monitoring Systems).
- Triple simultaneous output (Amp) for global, predictive and advanced diagnostic analysis.
- Internal Envelope and RMS Processing which offloads computational work to the receiving PLC.
- Standard 0-10V DC interfaces for direct reading and simplified industrial integration.
- Parallel AC output for manual inspection routes without interrupting continuous monitoring.
Technical Frequently Asked Questions
No, the MTN/1181 already processes the signal internally (Amp). Its RMS Speed and Envelope outputs deliver 0 to 10V DC directly, ready to be connected to any standard PLC analog input card.
2. Can I read the AC output while the PLC is monitoring 0-10V?
Yes, the three channels are completely independent and transmit in parallel. An analyst can connect their FFT analyzer to the AC output without affecting the DC readings being recorded by the control system.
3. Does it require standard IEPE power?
No, due to its internal triple-channel electronics, it requires a separate 15-24V DC power supply (approx. 10mA consumption), different from the 4mA constant current standard used in basic sensors.
