High Temperature Accelerometer MTN/1105C
- Manufacturer: Monitran
- Category: Accelerometers and Vibration Sensors, Amplified, SENSORS
Piezoelectric load accelerometer (pC output), without electronics in the sensor head, for continuous operation at temperatures up to 250 °C. Load sensitivity of 50 pC/g (nominal). Applications: industrial furnaces, gas turbines and engine exhausts; fault detection in bearings and gears in thermal machinery.
It requires a Monitran in-line charge amplifier, located in an area with a maximum temperature of 120°C, which converts the signal to 100 mV/g. The head connects with a shielded ETFE integral cable, which withstands 265°C and has no intermediate connectors in the heat zone. The cable length is configurable, typically 5 m.
Frequency response: 0.8 Hz to 12 kHz (±3dB). Dynamic range: ±80 g. Mounted resonance: 18 kHz (nominal). Stainless steel body, IP67, galvanically isolated base. Mounting: M6, M8, 1/4″ UNF, or Quick-Fit adapters. Models: MTN/1105C (top entry) and MTN/1105SCE (side entry).
- Temperature of 250 °C on contact surface (continuous operation).
- ETFE sealed integral cable, up to 265 °C.
- Printhead without electronics.
- Stainless steel, IP67.
Technical Frequently Asked Questions
1. Why does the MTN/1105C version with an integrated cable exist?
Because there is no connector on the head, there is no disconnection due to vibration, nor contamination or corrosion of the connector in the high-temperature area. The integral ETFE cable is sealed.
2. What care does the high-temperature cable require?
Although it can withstand up to 265°C, it should be kept away from incandescent surfaces or sharp edges. If there are mechanical risks, a flexible stainless steel conduit to the in-line amplifier is recommended.
3. Is a specific load amplifier necessary?
Yes. The MTN/1105C outputs a picoCoulomb (pC) signal that a standard IEPE device cannot read. A Monitran charge amplifier is required to convert the signal to 100mV/g.
