MTN/1107 Industrial Accelerometer
- Manufacturer: Monitran
- Category: Accelerometers and Vibration Sensors, Amplified, ATEX, SENSORS
Vibration monitoring in heavy industrial environments requires sensors that combine high sensitivity with exceptional mechanical robustness. The MTN/1107 series of industrial accelerometers is specifically designed for these applications, providing an isolated AC output signal that enables accurate detection of both low-frequency imbalances and early-stage bearing failures.
This constant-current piezoelectric sensor stands out for its technical versatility, allowing it to cover a wide range of vibration levels depending on the chosen configuration. Its top-entry design facilitates installation in assets where lateral space is limited, while its isolated base prevents ground loop problems that could degrade the signal in plants with a high concentration of electrical machinery. The output signal is linear and proportional to acceleration, facilitating its integration into continuous monitoring systems.
Manufactured entirely from stainless steel and with an IP67-rated hermetic seal, the MTN/1107 is capable of operating in extreme conditions, withstanding temperatures from -55°C to 140°C. Depending on the required installation variant, it can be supplied with integral ETFE cable or certifications for hazardous areas, ensuring reliable data transmission to control cabinets or portable data collectors.
- Wide response range from 2 Hz to 10 kHz for a complete diagnosis.
- Extreme thermal resistance operating temperature range from -55°C to 140°C.
- Stainless steel construction with IP67 sealing for corrosive environments.
- galvanically isolated base to eliminate electrical interference.
Technical Frequently Asked Questions
1. What advantage does the "Isolated Base" configuration offer?
The isolated base breaks the galvanic loop between the machine and the data acquisition system. This is critical in industrial plants where 50/60 Hz electrical noise can contaminate the vibration signal, inaccurate low-frequency diagnostics.
2. What is the recommended mounting torque for this sensor?
To ensure a flat frequency response up to 10 kHz, the sensor must be mounted securely using a torque of 8 Nm. Improper mounting can reduce the resonant frequency and affect the accuracy of high-frequency readings.
3. Is this sensor suitable for areas with a risk of explosion?
The base model is designed for safe areas. For environments with a risk of explosive atmospheres, there is the MTN/1107IC version, which has ATEX and IECEx intrinsic safety certifications for hazardous areas.
