Elevator Ride Quality, Vibration & Sound 

Ride Quality Measurement & Analysis for the Elevator/Escalator Industry

Physical Measurement Technologies’ EVA-625 Elevator Vibration Analysis system and EVA Vibration Analysis Tools software has quickly become the global standard for the measurement of elevator and escalator ride quality, and vibration & sound. Designed to meet international standards for the recording and analysis of elevator and escalator vibration and sound, only the EVA system allows all elevators and escalators to be measured, analyzed, and documented absolutely, easily and at a Very Low Cost. Through continuous refinement & enhancement, the EVA system remains the product of choice for the measurement and analysis of elevator/escalator ride quality, and vibration & sound, while PMT has become the world’s number one supplier of high accuracy instrumentation for the vertical transportation industry.

Elevator & Escalator System Quality Control, Diagnosis, & Inspection

Elevator ride quality is a first indicator of quality design, installation, and service. The EVA system includes powerful
tools to assist in quality improvement in all areas of the elevator mechanical and control system. The highly accurate
response of the EVA system, and the analysis capabilities offered by the EVA Vibration Analysis Tools software allow
technician to engineering level personnel to rapidly identify problem areas and perform corrective actions. Only the
EVA system provides the ability to measure the vibration and sound that people feel and hear and analyze the broadband
vibration and sound that is the result of the function of all dynamic aspects of the elevator system. With a little
practice, problems with roller guides, rail joints, motor control systems, and other dynamic elements can be identified in
minutes and repairs targeted precisely. Quality of installation and service can be improved dramatically. Because of the
simplicity of the EVA system and the information that is returned, the EVA-625 offers unmatched capabilities as an
inspection and fast survey tool. The condition of the elevator can easily be compared year after year.
