MTN/1100 Industrial Accelerometer
- Manufacturer: Monitran
- Category: Accelerometers and Vibration Sensors, SENSORS
The MTN/1100 industrial accelerometer is an IEPE (Integrated Electronics Piezo-Electric) type piezoelectric sensor designed for vibration monitoring in general-purpose rotating machinery. Its top-entry architecture and constant voltage output of 100mV/g make it the standard for data collection and asset protection in sectors such as the paper industry, water treatment, and general plant services.
Technically, the sensor stands out for its linear frequency response from 2 Hz to 10 kHz (±5%), with a measurement range extending from 0.8 Hz to 15 kHz at its -3dB cutoff points. This versatility allows for the detection of a wide range of mechanical faults, including imbalances, misalignments, and bearing defects. The device operates on a constant current power supply (0.5 to 8mA), making it compatible with most data collectors and vibration protection systems on the market.
Structural integrity is ensured by a sealed, IP67-rated stainless steel housing. The design includes a galvanically isolated base to prevent interference from ground loops, ensuring a clean signal even in environments with high electromagnetic activity. Connection is made via a standard military-grade 2-pin connector (Mil-C-5015), providing a reliable mechanical connection resistant to continuous machinery vibrations.
- Nominal sensitivity of 100mV/g for optimal resolution in industrial measurements.
- Wide temperature range from -55°C to +140°C for applications in extreme environments.
- Isolated base and IP67 seal for maximum reliability and reduction of electrical noise.
- Mil-C-5015 Connector which ensures robust and standardized industrial connectivity.
Technical Frequently Asked Questions
1. What type of wiring does the 2-pin connector require?
The MTN/1100 uses a Mil-C-5015 connector that requires a two-conductor shielded cable. Pin A is for signal/power and pin B is for common return. It is recommended to use cables with neoprene or stainless steel boots to maintain the IP67 protection rating of the connection.
2. What is the mounted resonance of the sensor and how does it affect the measurement?
The nominal mounted resonance is 18 kHz. This value is critical as it defines the upper limit of the sensor's accuracy; vibration measurements must be kept significantly below this frequency (typically down to 10-12 kHz) to avoid errors due to resonance amplification.
3. Is the MTN/1100 compatible with magnetic bases?
Yes, the sensor has a female mounting thread (typically 1/4″-28 UNF or M6) that allows direct attachment of magnetic bases for portable inspections or the use of threaded mounting studs for permanent, high-precision installations.
