The 89477-20 is a specialized interconnect cable engineered to provide the critical electrical link for Bently Nevada's 330500 Velomitor Piezo-velocity Sensor. This cable is a fundamental accessory that enables the sensor's velocity signal and power to be transmitted to monitoring systems. Constructed with two-conductor 18 AWG twisted and shielded wire, the 89477-20 is designed to ensure signal integrity by minimizing electrical noise and interference, which is essential for accurate vibration measurement in industrial environments.
At the sensor end, the 89477-20 is terminated with a right-angle two-socket plug. This connector is designed to mate securely with the 330500 sensor, and the right-angle design can be advantageous in tight installation spaces, helping to reduce strain on the connection and allowing for a more compact routing of the cable.
The 89477-20 is specified for use with the 330500 Velomitor, a specialized piezoelectric accelerometer with embedded integrated electronics. This solid-state sensor measures absolute vibration and, due to its lack of moving parts, can be mounted in any orientation without affecting its performance or calibration.
As a dedicated component of the Bently Nevada measurement ecosystem, the 89477-20 is more than just a wire; it is a matched accessory that ensures compatibility and performance. When used to connect the 330500 sensor to its intended monitor or the 21128 housing, the 89477-20 completes the signal chain necessary for effective condition monitoring.

FAQS
The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
What is the purpose of the 89477-20 cable and which sensor is it designed for?
The 89477-20 is a dedicated interconnect cable used to connect the Bently Nevada 330500 Velomitor Piezo-velocity Sensor to a monitoring system or the 21128 Velocity Transducer Housing. It transmits both power to the sensor and the velocity signal from the sensor.
What are the key specifications of the 89477-20 cable's construction?
The 89477-20 is built as a two-conductor cable using 18 AWG wire. The conductors are twisted and the cable is shielded. This construction is critical for minimizing electromagnetic interference (EMI) and ensuring a clean, accurate vibration signal is delivered from the solid-state 330500 sensor to the monitoring equipment.
What types of connectors are on each end of the 89477-20 cable?
The 89477-20 has a right-angle two-socket plug on the end that connects to the 330500 Velomitor sensor. The opposite end features stripped wires with attached terminal lugs, which are designed for connection to standard screw terminals on a monitor, housing, or terminal block.
What does the "-20" in the part number 89477-20 indicate, and what length options are available?
In the part number 89477-20, the "-20" typically denotes the cable's length, which in this case is 20 feet (approximately 6.1 meters). This cable is available in a range of lengths from a minimum of 2.0 feet (0.6 m) up to a maximum of 99 feet (30 m) to suit different installation layouts.
