FAQ

What is the primary difference between Velomitor CT and standard Velomitor?

The CT version focuses on low-frequency performance specifically for cooling tower fan speeds.

Can I install the 190501-04-00-CN in any orientation?

Yes, this transducer functions accurately at any mounting angle.

Why is my bias voltage reading different from 10.1 Vdc?

Check for cable damage or power supply issues in the monitor rack.

Does this unit require external power?

The transducer requires constant current power typically provided by the monitoring system.

How do I ensure the sensor survives 100% humidity?

Use properly sealed MIL-spec connectors and weather-proof conduit for the cabling.
