CA901 144-901-000-282

CA901 144-901-000-282 is a high reliability piezoelectric vibration sensor designed for extreme industrial environments. Its core function is to convert mechanical vibration into charge signals through the piezoelectric effect. Combined with an external signal conditioner (such as IPC707 or IPC704), it can achieve accurate vibration data analysis, providing key support for equipment health monitoring and fault warning.

Technical Parameters

Sensitivity: 10 pC/g (±5% tolerance), corresponding to 1.02 pC/(m/s²).

Operating temperature range: -196°C to +700°C (extreme version) / -54°C to +650°C (industrial version).

Frequency response: 3 Hz to 3700 Hz (standard mode), resonant frequency >17 kHz.

Dynamic range: 0.001 g to 200 g (corresponding to 0.00981 m/s² to 1962 m/s²).

Linearity: ±1% (within full range)

Lateral sensitivity: <5% (reducing multi-axis vibration interference)

Protection and certification: Explosion-proof certification (Ex ia, Ex nA), suitable for explosive gas environments.

Cable configuration: Optional mineral insulated (MI) cable to enhance signal transmission stability in high temperature environments.

Supporting Equipment and Installation

Signal conditioner: CA901 144-901-000-282 needs to be used with IPC707 or IPC704 charge amplifier to convert the charge signal into 4-20 mA or 0-10 V standard signal.

Installation method: CA901 144-901-000-282 provides threaded fixing or magnetic base to adapt to the surface structure of different equipment.

Maintenance requirements: The mineral insulated cable design reduces maintenance frequency and supports long-term calibration-free operation (it is recommended to conduct a comprehensive inspection once a year).
