portable vibration meters

   IRD811 is an Analog Vibration Meter cum Spike Energy Detector. It can be used to measure Vibration Amplitude in terms of Displacement, Velocity and Acceleration. It is also able to help assess anti-friction bearing condition via measurement of Spike Energy.

Purpose & Application

• Dual-role instrument for machinery maintenance.
   
• Used for periodic vibration checks to detect unbalance, misalignment, looseness, cavitation, rubs, and gear/bearing defects.
   
• Includes IRD Spike Energy™ (gSE™) detection circuit for early identification of bearing wear, cracks, micro-spalls, and lubrication issues.
   
• Analog meter display allows visualization of transient issues that digital meters may miss.
   
• With optional Fish Tail accessory, it can perform absolute shaft vibration measurements.
   

Key Features

• Wide measurement capability: from fractions of a micrometer to 3000 micrometers.
   
• 8 overlapping ranges for Acceleration, Velocity, Displacement, and Spike Energy (gSE).

 IRD-VM330D is a compact, rechargeable, portable handheld Vibration Meter designed to conform to ISO10816-3 and operate with a constant current accelerometer providing an accurate vibration measurement. Features comprise of the ability to store and transfer to PC up to 100 time-stamped readings, including; RMS, peak, peak-peak, crest factor and bearing conditions all on an easy to read vibrant colour LCD display. 

 ARGUS Tri-axial wireless vibration analyzer brings a new dimension to the world of predictive maintenance to easily diagnose the health of motors and any connected driven assets like pumps, fans, compressors, etc. It enables easy condition monitoring of rotary machines and detects faults well before equipment failure. ARGUS reduces maintenance costs and increases asset lifespan.

The super-compact, IP65 rated vibration sensor provides reliable data for continuous monitoring and remote diagnostics. This portable sensor simultaneously measures vibration in three directions and is used as both a Single-axial sensor & a Tri-axial sensor. The dedicated ARGUS app allows you to view and store the RMS values of Velocity & Acceleration, Time waveform, Velocity & Acceleration FFT spectrums on the smartphone. ARGUS can be mounted in any environment using a magnet, adhesive & stud.
