144-201-000-222 Meggitt Vibro-Meter CA201 Piezoelectric Accelerometer

Product Description
144-201-000-222 is the part number of Vibro-Meter CA201 shear-type piezoelectric accelerometer under Meggitt. It is a charge-output vibration sensor designed for high-temperature heavy-duty rotating machinery monitoring. It collects casing vibration acceleration signals and needs to work with an external charge amplifier (such as IPC707) to convert charge signal into standard voltage/current signal for VM600 or other machinery protection systems. This sensor adopts hermetically sealed metal housing and armored cable, suitable for gas turbine, steam turbine and other high-temperature, high-vibration industrial equipment.

Key Features

• Sensitivity: 100 pC/g ±5% @120Hz, charge output type
• Frequency response: 0.5Hz ~ 3000Hz (±5%), extended up to 4.5kHz
• Operating temperature range: -54℃ ~ +260℃, high temperature resistant design
• Measurement range: 0~200g peak, overload withstand up to 250g peak
• Shear piezoelectric structure, low transverse sensitivity ≤3%, good anti-interference ability
• Stainless steel hermetic sealing, armored integrated cable, shock and corrosion resistant
• Requires external charge conditioner, cannot directly connect to monitoring module
• Legacy sensor; CA202 is the upgraded replacement model, CA201 is mainly supplied as spare parts

Application Scenarios

• Gas turbine and steam turbine casing vibration monitoring
• Power plant combined cycle unit machinery protection system
• Oil & gas, refinery large compressor and pump vibration supervision
• Heavy rotating machinery condition monitoring and predictive maintenance
• VM600 vibration monitoring system spare sensor replacement

FAQ

Q: Does CA201 144-201-000-222 output 4-20mA signal directly?
A: No. It outputs charge signal, must match charge amplifier IPC707 for signal conversion.

Q: What is the difference between CA201 and CA202?
A: CA202 is upgraded version with improved high-temperature stability; CA201 is legacy spare part.

Q: Can it be used in hazardous area?
A: Explosion-proof variants are available, subject to the certificate of the specific batch.
