The Bently Nevada 3500/22 transient data interface, as a key device in the field of industrial monitoring, plays an important role in ensuring the stable operation of machinery and equipment.

It is the bridge between 3500 monitoring systems and compatible software such as System 1 condition monitoring and diagnostic software and 3500 system configuration software. Its main function is to work with M-series monitors (like 3500/40M, 3500/42M, etc.) to continuously collect steady-state and transient dynamic (wavefo

rm) data. The data is transmitted to the host software at high speed and stably through Ethernet link, which is convenient for technicians to carry out remote monitoring and in-depth analysis.

In terms of data acquisition, the 3500/22 transient data interface performs well. It supports the four Keyphasor signals of the 3500 system, determines the speed range support based on the number of active dynamic channels, and supports speed inputs up to 20kHz that occur multiple times per rotation. During startup/shutdown, data can be collected at predetermined speeds and time intervals, and the speed intervals can be individually programmed to increase and decrease.

The alarm data acquisition function of this interface is also very powerful. The waveform data of 2.5 minutes is collected every 10 seconds before the alarm, and the waveform data of 1 minute is collected every 10 seconds after the alarm. At the same time, static values at one-second intervals 10 minutes before the event and 1 minute after the event, as well as static values at 100-millisecond intervals 20 seconds before the event and 10 seconds after the event.

From the technical parameters, the 3500/22 transient data interface power consumption is only 10.5 watts. The front panel is equipped with a USB-B port for local connection and data interaction. Supports 10Base-T / 100Base-TX Ethernet or 100Base-FX optical Ethernet communication. The operating temperature range is -30 ° C to + 65 ° C, the dimensions are 241.3 mm x24.4 mm x241.8 mm, and the weight is 0.82 kg.

With high-precision data acquisition capabilities and real-time data transmission functions, the 3500/22 transient data interface is widely used in rotating equipment monitoring, machinery protection, asset condition monitoring, vibration analysis and many other industrial monitoring scenarios, providing strong support for enterprises to achieve efficient and reliable equipment operation and maintenance

The Bently Nevada 3500/22 Transient Data Interface is the Bentley Nevada 3500/22 transient Data interface, which is described below:

Functional characteristics

Powerful data acquisition function: It can cooperate with M series monitors (such as 3500/40M, 3500/42M, etc.) to continuously collect steady-state and transient dynamic (waveform) data, collect instantaneous information of mechanical vibration and other physical changes, and capture high-frequency and short time signal changes. Support for four Keyphasor signals for 3500 systems, speed range support depending on the number of dynamic channels active, and speed inputs up to 20kHz that occur multiple times per rotation.

Data storage and transmission stability: With data storage capability, it can record the transient data collected and transmit it to the host software through the Ethernet link, such as System 1 condition monitoring and diagnosis software and 3500 system configuration software, supporting 10Base-T/100Base-TX Ethernet or 100Base-FX optical Ethernet communication. Ensure high speed and stable data transmission.

Multiple data acquisition modes: Data can be collected at predetermined speeds and time intervals during startup/shutdown, speed intervals can be individually programmed to increase and decrease, and instantaneous data collection begins when machine speed is detected in two programmable Windows. For alarm data, 2.5 minutes of waveform data is collected every 10 seconds before the alarm, 1 minute of waveform data is collected every 10 seconds after the alarm, and the static value of 10 minutes before the event and 1 minute after the event is collected at the interval of one second. And static values at 100-millisecond intervals 20 seconds before the event and 10 seconds after the event.

Other features: USB-B front panel for local connection and data interaction. Equipped with the rack reset button, you can reset the rack. With a configuration key lock, 3,500 racks can be switched between "Run" and "program" modes to ensure the security and stability of the system configuration.
