Monitran MTN/1330 Triaxial Accelerometer

Manufacturer: Monitran
Category: Accelerometers and Vibration Sensors, Amplified, SENSORS

Measuring vibrations in complex structures or aerospace test benches requires capturing the system's dynamics along all three spatial axes simultaneously. Installing three individual sensors not only triples the cost and cabling, but also introduces phase errors and mechanical misalignment that invalidate the results of fatigue and resonance tests.

This piezoelectric triaxial accelerometer overcomes this complexity by integrating three independent sensing elements into a single compact aluminum chassis. It provides three isolated AC outputs (100 mV/g per axis) via a 4-pin M12 industrial connector, ensuring perfect time correlation between the X, Y, and Z axes. Its side-exit design allows for low-profile mounting, ideal for installation on surfaces where vertical space is limited, such as engine cowlings or automotive frames.

Designed with isolated internal electronics to minimize noise and maximize bias voltage stability, this device is an essential tool in R&D laboratories and for vibration monitoring of high-precision rotating machinery. Its mounting via a single M6 central screw simplifies the process of mechanically aligning the shafts with respect to the machine.

Simultaneous measurement in the X, Y, and Z axes with a sensitivity of 100 mV/g.
Simplified connection via 4-pin M12 connector.
Linear frequency response of 2 Hz to 9 kHz per axis.
Lightweight structure aluminum (100g) to avoid added mass effects.

Technical Frequently Asked Questions

1. Why is the body made of aluminum instead of stainless steel?
The use of aluminum allows the sensor's weight to be kept to just 100 grams. In research and development (R&D) and aerospace applications, minimizing the sensor's mass is critical to avoid altering the natural resonant frequency of the structure being measured.

2. How are the pins arranged on the M12 connector?
The 4-pin connector dedicates one common 0V pin and three individual pins for the X, Y, and Z axis output signals. This allows all three vibration signals to be carried through a single shielded cable to the acquisition system.

3. What level of environmental protection does this triaxial sensor offer?
The MTN/1330 has an IP54 protection rating. It is optimized for laboratory environments, test benches, and protected enclosures. If you require a version for total immersion or extreme chemical environments, please see our IP67/68 sealed variants.
