The 3300/35-12-02-01-00-00 is a classic dual-channel, six-level alarm tachometer, belonging to the 3300 series mechanical protection system. It is specifically designed for monitoring rotating machinery and features default alarm and protection interlocks.
a 3300 XL 8 mm probe or 3300 5 mm probe
a 3300 XL extension cable
a 3300 Proximitor Sensor
The system provides an output voltage directly proportional to the distance between the probe tip and the observed conductive surface. It is capable of both static (position) and dynamic (vibration) measurements, and is primarily used for vibration and position measurement applications on fluid-film bearing machines, as well as Keyphasor® and speed measurement applications.

Oil & Gas
Monitor the compressor shaft speed and cut off the power source via relay interlock when abnormal acceleration occurs to prevent rotor damage.
Thermal Power Generation
Before or after the unit starts up, extremely low speeds are monitored by magnetoelectric sensors to ensure the normal operation of the turning gear and prevent rotor thermal bending.
Steel & Metallurgy
By monitoring the rotational frequency of large blowers, the system assists process engineers in adjusting the air supply volume and provides alarms for unit safety limits.
Mining & Cement
Before maintenance or restarting, confirm that the massive mill rollers are completely stationary and ensure the safety of personnel entering the interior to work.
Water Treatment & Environment Monitor the speed of large pumps used for drainage or water transfer to prevent mechanical damage caused by pump reversal due to backflow.
When installing and configuring the 3300/35-12-02-01-00-00 module, it is critical to verify that the field sensors are Magnetic Pickups, as this specific option (-02) is incompatible with proximity probes. Additionally, the number of teeth (Events per Revolution) must be accurately set to ensure the displayed RPM matches the actual shaft speed. Given its 6-alarm capability, relay logic configurations must be cross-checked to prevent nuisance trips or fail-to-act scenarios at critical protection setpoints. Furthermore, while 3300 series modules are hot-swappable, they should only be handled after ensuring the system is in a safe bypass mode; regular verification of raw signal quality via the front-panel Buffered Output is also recommended to rule out potential faults caused by fluctuations in sensor gaps.
It is the Dual Channel 6-Alarm Tachometer module in the Bently Nevada 3300 system.
How to use 3300/35-12-02-01-00-00 for monitoring?
Insert the module into the 3300 frame and connect it to the field speed sensor. The module receives pulse signals, displays the speed in the LED window on the front panel, and connects to the DCS or Emergency Stop System (ESD) via the relay output on the rear panel.
What sensor inputs are compatible with 3300/35-12-02-01-00-00?
Based on its selection (-02), it is specifically designed to receive passive signals from magnetic pickup sensors.
What are the mechanical requirements for installing 3300/35-12-02-01-00-00?
It is a standard full-height module and must be installed in a Bently Nevada 3300 series rack.
How many alarm setpoints does 3300/35-12-02-01-00-00 have?
It features 6-level alarms, allowing you to set limits for various states such as overspeed and underspeed.
