Features:
- Case-insulated differential charge output for high-temperature vibration measurement.
- Integral mineral-insulated cable protected by a double-braided outer layer.
- Hermetically welded nickel-alloy and stainless-steel sensor construction.
The CA134 144-134-000-612 senses absolute vibration through a compression-mode piezoelectric element while keeping the electrical circuit isolated from the outer case.
A nominal 10 pC/g charge sensitivity allows CA134 144-134-000-612 signals to be conditioned by the IPC70x family across the sensor's broad dynamic range.
The sealed cable-and-sensor assembly gives CA134 144-134-000-612 a continuous operating range reaching 500 °C and a peak shock tolerance of 1,000 g.
The VIBRO-METER CA134 144-134-000-612 Piezoelectric Accelerometer may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Charge-output interface
- Sensing principle: A compression-mode piezoelectric element converts housing acceleration into charge.
- Electrical isolation: The two output conductors remain insulated from the sensor case.
- Nominal sensitivity: The differential signal is rated at 10 pC/g with a ±5% tolerance.
- Conditioning stage: An IPC70x charge converter accepts the two-pin sensor output.
Sensor and cable installation
- Fastening: Three M4 × 16 Allen screws with spring-lock washers secure the sensor body.
- Tightening torque: Each mounting screw uses a nominal 4 N·m torque.
- Mounting surface: Electrical insulation beneath the case is not required.
- Cable termination: The fixed mineral-insulated lead ends in a two-pin high-temperature connector.
Thermal and mechanical limits
- Continuous temperature: The complete sensor assembly operates from -54 to 500 °C.
- Dynamic acceleration: The measurement span extends from 0.001 to 500 g peak.
- Transient loading: Peak acceleration spikes up to 1,000 g are permitted.
- Sealing: Hermetic welding closes the nickel-alloy and stainless-steel housing.
Specified measurement duties
- Gas turbines: The sensor is specified for vibration measurement on very high-temperature turbine structures.
- Extreme heat: Its integral cable arrangement supports locations where ordinary cable assemblies cannot tolerate the temperature.
- Hazardous locations: Intrinsic-safety approval variants include the TIIS provisions assigned to 144-134-000-612.
- Wide-band monitoring: The response range covers both lower-frequency casing motion and higher-frequency vibration components.
