By purchasing this item, you agree to the Terms & Conditions, ApterPower is not an authorized distributor for listed manufacturers or tradenames and therefore the manufacturer's warranty does not apply. All our products come with ApterPower's 1-year warranty.
The 991-01-XX-01-CN Thrust Transmitter is designed for OEMs of centrifugal compressors, small pumps, motors, and fans that require a simple yet precise method for monitoring axial displacement. It works with a single 3300 NSv proximity probe and extension cable (available in 5 m and 7 m system lengths), converting the mechanical shaft movement into a 4–20 mA industry-standard signal for integration into machinery control systems and protection logic.
Key features include an integrated Proximitor sensor, non-interfering zero and span adjustments, and compatibility with PROX OUT and COM terminals to provide diagnostic signals, including vibration and gap voltage. These features support both real-time monitoring and preventive maintenance strategies.
The transmitter is easy to install, with 35 mm DIN-rail clips as the standard mounting option, and its compact potted construction ensures reliable operation in high-humidity environments. It is engineered for stable performance even in confined spaces where precise machinery monitoring is critical.
By providing accurate, loop-powered 4–20 mA output, the 991-01-XX-01-CN allows operators to monitor shaft thrust and detect potential mechanical issues early, enhancing reliability and reducing downtime for industrial equipment.
