Hand-held Vibration Analyzer Type 2250 H

The Type 2250 H vibration analyzer can be used for a wide variety of vibration measurement applications and with a range of accelerometers dependent on the level, position and environment in which the measurements are to be made. Some of the more common applications for the 2250 H 001 are described below:

• Quality testing and Inspection
• Product Development
• Machinery analysis and troubleshooting
• Building vibration

Features of Type 2250 H
Type 2250 H quickly, easily and reliably presents the operator with the measurement result in the palm of their hand. The hardware features and operating functionality designed to facilitate this include:

• Large, high-resolution, touch-sensitive colour screen
• Traffic light status indicator
• Plug-in rechargeable Li-ion battery
• Data storage on plug-in SD and CF memory cards
• 120 dB dynamic range
• Wireless LAN connectivity
• Vibration signal recording for post analysis
• Robust and environmentally protected (IP 44)

Type 2250 H - Handles Troubleshooting Applications
Type 2250 H includes the analysis tools and measurement units for a wide range of troubleshooting applications. Measuring the vibration level of a pump, fan or motor is a simple and effective technique for determining the correct operation of the machine or component. Higher than expected vibration magnitudes may indicate possible problems with shaft misalignment, loosening of components or general wear on bearings and gears.

Quality Testing and Inspection – Tolerance Windows
Quality control involves examining and monitoring parts, assemblies and sub-assemblies in order to check adherence to standardised vibration tolerances. Measuring and analysing that vibration can be used to detect assembly faults and ensure compliance with required standards.

New products have characteristic sound and vibration spectra; deviations indicate problems:

Spot checks: Perform quick quality checks of a production batch. The Tolerance Windows feature in 2250 H 001 with Pass/Fail indication makes quality control measurements easy.

Product Development
Early component performance evaluation can greatly improve product design. The analyzer’s dual overlay display makes it easy to compare measurements between design iterations and to benchmark competitive and previous generation products.

Measurement Organisation
Whatever your application there is more to your measurements than just the bare numbers. With annotations it is easy to attach voice commentary, notes and images (with Type 2270 only) to the measurement results.

Type 2250 H also supports customised metadata fields which are supplementary information entries about your measurement that make archiving, retrieving and post-processing data easier and more efficient. Examples of metadata would be operator name, device test number, batch number, date and time etc.

Signal Recording Option BZ-7226
Signal Recording Option BZ-7226 enables vibration signal recording for later playback or analysis. The recording can be automatic (lasting for the duration of the measurement), controlled manually, or last as long as the limit level is exceeded.

PC Software – utility program BZ 5503
Utility program BZ-5503 is an all-purpose program forming the information link to (and from) your analyzer Its primary functions are to manage and archive user data, handle updates, upgrades and licensing of application software; and to control the analyzer’s data from a PC.

Upgrade to Class 1 Sound Level Meter
Is there an upgrade path to a full 2250 Class 1 Sound Level Meter for 2250 H owners? Yes, item no BZ 7222-UPG adds the sound level meter application to 2250 H thereby converting your vibration analyzer into a precision Class 1 Sound Level Meter.
