MTN/1105C Industrial Accelerometer Sensor | 100mV/g | -55 to 250°C
The MTN/1105C Industrial Accelerometer is a high-precision device designed for vibration analysis in extreme environments, with an operating capacity up to 250 °C. Its standard architecture includes a stainless steel core, with no electronic components in the sensor head, ensuring resistance to high temperatures and corrosion. Operation is based on an inductive charging principle, where the signal generated by the sensor is amplified by an external charge amplifier connected with high-temperature (265 °C) cable. This design allows for a separation of up to 5 meters between the sensor and the amplifier, located in areas with temperatures below 120 °C.
The MTN/1105C electromagnetic telemetry operates in a frequency range of 2 Hz to 10 kHz, with a response accuracy of ±5%. Its reactive inertia is optimized to minimize distortion in high-acceleration applications, while the material's harmonic expansion ensures thermal stability. The sensor output is 100 mV/g, with a ground noise of 1 mg and a dynamic range of ±50 g. The system includes an integrable charge amplifier (MTN/CA003) with a 12 V DC bias voltage, allowing direct connection to monitoring systems via SMC, BNC, or integrated cables.
Dual Engineering Audit (FAQ)
The sensitivity of the MTN/1105C (100 mV/g) remains stable across the range of -55 °C to 250 °C thanks to its stainless steel design and the absence of electronics in the sensor head. Electromagnetic telemetry is compensated by the external charge amplifier, which operates in a temperature range of -25 °C to 125 °C, ensuring a linear response even under extreme conditions. The material's harmonic expansion minimizes thermal distortion, maintaining the accuracy of the 95% in high-vibration applications.
The 8 Nm mounting torque of the MTN/1105C ensures a rigid attachment to high-stress surfaces, such as turbines or paper machinery, where vibration is intense. This torque optimizes force transfer between the sensor and the substrate, reducing reactive inertia and improving the radial concentricity of the signal. Furthermore, the IP67 rating protects against dust and water ingress, allowing its use in humid or particulate industrial environments.
