Inline Cable Amplifier CA

Product catalog summary

Overview
The in-line cable strain gauge amplifier is designed to supply standardized current signals for machinery and equipment without the need for additional external components. Its proximity to the sensor minimizes noise interference, enhancing signal amplification and transmission. It is compatible with nearly all HAEHNE sensors.

Scope of Supply
The amplifier comes in a stainless steel housing with a 4-meter signal cable and a 1-meter sensor cable, including a fastening clamp. It is factory-connected to the respective sensor.

Variants

AU: 1 voltage output ± 10 V
AC: 1 current output 4…20 mA

Special Features

Minimal space requirement
Excellent EMC characteristics
Reduced cabling needs

Cable Amplifier CA Scope of Supply Amplifier in stainless steel housing with 4 m signal cable and 1 m sensor cable, incl. fastening clamp Factory-provided connected to the respective sensor Variants - AU: 1 voltage output ± 10 V - AC: 1 current output 4…20 mA Special Features • Minimum space requirement • Very good EMC characteristics • Minimal amount of cabling The in-line cable strain gauge amplifier supplies standardized current signals for direct use in machinery and equipment without additional external components. The location of the amplifier in close proximity to the sensor reduces noise interference and results in better signal amplification and transmission of the current output. Practically all HAEHNE sensors can be powered with this cable amplifier. amplifier current supply Signal *) With CA-AU this line does not exist.
