GE Industrial Vibration Transmitter 344A9322G001

GE 344A9322G001 is a 4-20mA integrated vibration transmitter in Bently Nevada series, dedicated to continuous vibration monitoring of rotating machinery (such as motor, pump and fan), which directly converts mechanical vibration into standard current signal and realizes real-time warning of equipment health state.

Core functions and characteristics

Three-parameter measurement:

The synchronous output vibration speed (RMS), displacement (peak and peak) and acceleration value fully reflect the mechanical state.

Wide band monitoring:

Supporting frequency range of 10~1000Hz, covering common mechanical failure characteristic frequency (imbalance/misalignment/bearing damage).

Plug and play:

Two-wire wiring (24V DC loop power supply), built-in signal conditioning circuit, no additional transmitter required.

Industrial rugged design:

Stainless steel enclosure, IP66 protection, high temperature resistance (- 40 - 85 ℃), EMI resistance in accordance with IEEE 472.

Safety certification:

ATEX/IECEx Ex certified (Zone 2/22) for hazardous areas.

Typical application scenarios

Early warning of bearing wear of centrifugal pump in chemical plant.

Plant cooling tower fan unbalance real-time monitoring.

Interlocking shutdown protection for excessive vibration of reciprocating unit in compressor house.

Note: this model is a classic model, and the new upgraded model is 3500/42M (added with digital communication interface).

GE 344A9322G001 Vibration Sensors: Intelligent Watchdog for Rotating Machinery

GE Bently Nevada 344A9322G001 is a benchmark 4-20mA integrated vibration transmitter for predictive maintenance of industrial equipment. It is specially designed for continuous health monitoring of rotating machinery such as motors, pumps, fans and compressors, and converts complex mechanical vibration signals into quantifiable and transmittable standard current signals, providing core data support for equipment failure warning.

Technical highlights and core values

Multi-dimensional diagnosis

Synchronous output vibration speed (RMS), displacement (peak and peak value) and acceleration three parameters, accurately capture the typical fault characteristics of unbalance, bearing wear and shaft misalignment, with frequency response range of 10~1000Hz covering 90% of mechanical failure spectrum.

Minimal deployment

Two-wire loop power supply (18-30V DC), directly output 4-20mA signal to PLC/DCS, without additional transmission module, reducing system complexity and wiring cost.

Industrial grade solid

L stainless steel shell and IP66 protection against oil, dust and high pressure water jet; -Wide temperature tolerance of 40 ℃ - 85 ℃, ensuring stable operation of severe scenes such as steel making and offshore platform.

Safety Compliance

ATEX/IECEx Zone 2/22 explosion-proof certification, supporting SIL 2 security level, meeting the deployment requirements of petrochemical, coal mine and other hazardous areas.

Industrial application scenarios

Energy and power: interlock shutdown protection for excessive vibration of gas turbine to avoid blade fracture accident.

Petrochemical: early wear warning of centrifugal pump bearing to reduce loss due to unplanned shutdown.

Metallurgical manufacturing: condition evaluation of steel rolling mill gearbox, optimization of preventive maintenance cycle.

Upgrade recommendation: the new 3500/42M supports Modbus TCP digital communication, which is suitable for intelligent upgrade project.
