Triple Output Vibration Sensor MTN/1181

The MTN/1181 is a vibration sensor with integrated signal conditioning electronics (Amp) and three simultaneous, independent outputs. It requires a 15-24V DC power supply (nominal consumption 10 mA). It does not require external converter modules for PLCs, SCADA systems, or building management systems (BMS).

Departures:

• DC 0-10V output proportional to RMS speed (standard range 0-25 mm/s), in the 10 Hz to 1 kHz band. Application: monitoring the overall condition of the machine according to ISO 10816.
• DC output 0-10V proportional to the acceleration envelope (Envelope g), standard range 0-10g. Application: detection of metal impacts, lubrication failures and bearing race defects.
• AC analog acceleration output with standard sensitivity of 100 mV/g (raw waveform), for spectrum analysis (FFT) with a handheld data collector connected to the sensor.

IP67 protection rating. Weight: 400 grams. Dimensions: 46 mm x 46 mm x 76.7 mm (width x depth x height). Stainless steel housing. Operating temperature: 0 to 90 °C. Application: Condition Monitoring Systems (CMS).

• Three simultaneous outputs (Amp): RMS speed, acceleration envelope, and AC acceleration.
• Internal envelope and RMS processing, without calculation in the receiving PLC.
• 0-10V DC outputs for direct reading.
• Parallel AC output for manual inspection routes without interrupting continuous monitoring.

Technical FAQs

1. Is an external signal conditioner needed to connect to the PLC?
No. The MTN/1181 processes the signal internally (Amp). The RMS and envelope speed outputs deliver 0 to 10V DC, for connection to an analog PLC input.

2. Can the AC output be read while the PLC is monitoring 0-10V?
Yes. The three channels are independent and transmit in parallel. An FFT analyzer connected to the AC output does not affect the DC readings of the control system.

3. Does it require standard IEPE power?
No. It requires an independent 15 to 24V DC power supply (approx. 10mA consumption), separate from the 4mA constant current of the basic IEPE sensors.
