MTN/2200 General Purpose Industrial Accelerometer
- Manufacturer: Monitran
- Category: Accelerometers and Vibration Sensors, Amplified, SENSORS
The MTN/2200 industrial accelerometer is an IEPE (constant current) type transducer designed for monitoring and detailed analysis of vibrations in rotating machinery. Its distinguishing feature is the integration of a highly stable piezoelectric element with an AC output isolated from the base, ensuring superior immunity to electrical noise and ground loops—critical factors for accuracy in inspection routes and permanent protection systems.
Technically, the sensor provides a nominal sensitivity of 100 mV/g with a linear frequency response from 2 Hz to 10 kHz (±5%), reaching 15 kHz at its cutoff points. This wide bandwidth allows for the diagnosis of everything from low-speed imbalances to high-frequency bearing raceway failures. Its robust stainless steel construction and IP67 hermetic sealing ensure a long operational life under harsh plant conditions, resisting exposure to lubricants and corrosive environments.
The versatility of the MTN/2200 makes it the standard sensor for a wide range of applications, from pumps and fans to gearboxes and compressors. Equipped with a 2-pin military connector (Mil-C-5015), it allows for a secure and standardized mechanical connection, compatible with the vast majority of portable data collectors and industrial data acquisition cards on the market.
- Isolated AC base output for a signal free of external electrical noise.
- Wide frequency range optimized for diagnosing bearings and gears.
- Airtight construction in stainless steel with IP67 protection rating.
- Compatible with IEPE power supply standard (0.5 to 8mA).
Technical Frequently Asked Questions
1. How does the MTN/2200 differ from the 1100 series?
Although both offer 100mV/g, the MTN/2200 is optimized for high-fidelity analysis with more robust base isolation and superior thermal stability, making it preferable for permanent installations where signal integrity is the highest priority against induced noise.
2. Is it possible to configure the sensor with other sensitivities?
Yes, the 2200 platform allows for custom sensitivity settings (e.g., 10mV/g for high acceleration levels or 500mV/g for low speeds), allowing the sensor's dynamic range to be adapted to the specific needs of the monitored machinery.
3. What permanent mounting options are available?
The sensor features a threaded base that accepts 1/4″-28 UNF, M6, or M8 studs, as well as Quick-Fit adapters for fast installation. For optimal high-frequency response, direct threaded mounting on a ground, flat surface is always recommended.
