Key Features
High-Temperature Vibration Measurement
The CA134 is designed for vibration measurement where the sensor must operate across a wide temperature range. The standard version supports continuous operation from −54°C to +500°C, subject to the manufacturer's specified installation and operating conditions.
Integral Mineral-Insulated Cable
Part number 144-134-000-613 includes an approximately 2 m mineral-insulated cable with double-braid protection. The integral construction reduces the need to select a separate cable at the sensor end and provides a high-temperature connection arrangement for the intended measurement chain.
Charge-Output Measurement
The CA134 generates an electrical charge in response to mechanical acceleration. Its output must be connected to a compatible charge converter or signal-conditioning device. Cable capacitance and the characteristics of the signal conditioner must be considered when selecting the complete measurement chain.
Hazardous-Area Applications
The CA134 product family has hazardous-area approvals. The exact protection method, certificate, and conditions of use must be checked for the specific part number and installation. The presence of an Ex approval for a product family does not remove the need to comply with the applicable site and installation requirements.
The CA134 uses a piezoelectric sensing element to convert mechanical acceleration into an electrical charge signal. When the sensor is rigidly mounted to a vibrating machine surface, the sensing element responds to the vibration transmitted through the mounting interface.
The resulting charge signal is passed through a compatible charge converter or signal-conditioning stage. The conditioned signal can then be processed by a suitable vibration monitoring or data acquisition system to evaluate machine vibration.
For the CA134 144-134-000-613, signal-chain selection is particularly important because the integral MI cable affects the electrical capacitance of the measurement chain. Verify the sensor, cable, and signal conditioner as a complete configuration before commissioning.
Compatible Systems and Typical Applications
The CA134 is a sensor rather than a standalone vibration monitoring module. It requires suitable signal conditioning and monitoring equipment.
Typical applications
Gas turbine vibration measurement.
Steam turbine vibration monitoring.
Compressor vibration monitoring.
High-temperature machinery condition monitoring.
Selected industrial installations involving potentially explosive atmospheres, subject to the applicable certification and installation conditions.
Other machinery vibration measurement applications within the sensor's specified operating range.
System integration considerations
The sensor can be considered for use in a Vibro-Meter measurement chain or a suitable data acquisition and machinery monitoring installation. However, the complete chain must be verified, including input type, charge conversion, cable capacitance, channel configuration, and any hazardous-area interface requirements.
Do not describe the CA134 as directly compatible with every VM600, DCS or PLC input. A charge-output accelerometer cannot automatically be connected to a generic voltage input without the appropriate signal conditioning.
Most importantly, the approximately 2 m MI cable on the 144-134-000-613 must be considered when choosing the signal conditioner. The manufacturer's IPC707 installation documentation identifies a cable-related limitation for CA134 integral MI cable versions used with IPC707 diagnostic functionality.

How to use the CA134 piezoelectric accelerometer
Installation Suggestions
Use rigid installation (threaded fixation)
Avoid installation on loose or resonant structures
The cable should be kept away from high electromagnetic interference sources
Supporting equipment

Q:1. What is the difference between 144-134-000-613 and 144-134-000-203?
A:The 000-613 version includes an approximately 2 m integral MI cable. The 000-203 version is the sensor-only variant. Cable configuration and measurement-chain compatibility must be checked before selecting a replacement.
Q:2. What is the sensitivity of the CA134?
A:The nominal sensitivity is 10 pC/g ±5%, specified at 120 Hz with a 5 g input under the manufacturer's stated calibration conditions.
Q:3. What is its frequency response?
A:The specified frequency response is 0.5–6,000 Hz. The response tolerance is ±5% from 0.5 to 3,500 Hz and less than 10% from 3,500 to 6,000 Hz.
Q:4. What is the operating temperature range?
A:The standard version supports continuous operation from −54°C to +500°C. A separately configured cryogenic version supports a minimum operating temperature of −253°C. Verify the exact version before ordering.
Q:5. Is this sensor suitable for gas turbines?
A:It is designed for vibration measurement in demanding environments, including gas turbine applications. The mounting location, vibration range, temperature, cable routing and monitoring system must be suitable for the application.
Q:6. Can it connect directly to a PLC or DCS analog input?
A:Not generally without suitable signal conditioning. The sensor provides a charge output, so the interface must be designed for that signal type before connecting to a monitoring or control system.
