Product Introduction
The Bently Nevada 170190-01 Dual Galvanic Isolator is a precision-engineered signal conditioning module designed to electrically isolate input and output channels between field sensors and monitoring systems. This dual-channel isolator is particularly useful in safety-critical and high-noise industrial environments where electrical separation is essential to protect sensitive equipment and personnel.
Manufactured by Bently Nevada, a global leader in condition monitoring solutions under Baker Hughes, the 170190-01 provides robust galvanic isolation to prevent ground loops, minimize signal interference, and ensure the integrity of vibration and dynamic signal measurements. It plays a critical role in applications where accurate data transfer without common-mode voltage issues is required, such as in hazardous or power-intensive machinery monitoring.
