Monitran MTN/1170 Industrial Accelerometer
- Manufacturer: Monitran
- Category: Accelerometers and Vibration Sensors, Amplified, SENSORS
Vibration monitoring in harsh industrial environments requires connection systems that can withstand mechanical wear and fluid contamination without signal loss. In critical applications such as large process pumps or fans, fixed cables can be a point of failure if they are cut or fatigued, further complicating maintenance and calibration tasks.
This constant-current piezoelectric accelerometer ensures reliable connectivity with a 2-pin C5015 military-grade weatherproof connector. Its galvanically isolated base architecture eliminates ground loop interference, enabling clean 100 mV/g signal transmission. As a top-entry sensor, it facilitates installation on machines where perimeter access is limited but there is sufficient headroom for cabling.
Made entirely of stainless steel with IP67 hermetic sealing, it is designed for use with portable data collectors or continuous monitoring systems. Its 19 mm diameter base allows for stable mounting even on moderately curved surfaces, ensuring a reliable frequency response up to 12 kHz.
- Robust industrial connection via 2-pin C5015 connector (MIL-C-5015).
- Linear frequency response of 2 Hz to 12 kHz with resonance at 22 kHz.
- Design of isolated base which prevents reading errors due to electrical noise in the plant.
- Operating temperature range from -25 °C to 120 °C.
Technical Frequently Asked Questions
1. What advantage does a military connector offer over an integral cable?
The C5015 connector allows for the replacement of damaged cables in seconds without removing the sensor from the machine. It also facilitates the use of portable data collectors, allowing the technician to connect their measuring equipment only during the inspection route.
2. Is it necessary to use an external insulator to prevent ground loops?
No. The MTN/1170 incorporates internal base isolation, which means that the sensor chassis is electrically separated from the measuring circuit, preventing leakage currents from motors from contaminating the signal.
3. Can it be installed outdoors or in areas with high humidity?
Yes, the sensor has an IP67 protection rating. Provided the appropriate coupling connector (MTN/MH002) is used, the system remains watertight against water jets and fine industrial dust.
