Electromechanical & servo-hydraulic testing machines – what’s the difference?

Get the inside scoop on the difference between electromechanical and servo-hydraulic Universal Testing Machines and work out which better suits your test and measurement needs.  

Universal Testing Machines

UTMs are a test and measurement solution designed to carry out a wide range of tests. They are capable of measuring and analyzing the physical and mechanical properties of sample materials by testing their performance when subjected to a variety of tensile or compressive forces. These highly versatile and customizable machines can be an integral part of any set up. 

They also come in variety of different forms – including those with electromechanical or servo-hydraulic systems. So how do you know which is most suitable for your QA process? We’ve got the low down.  

Electromechanical & servo-hydraulic driven machines explained

Electromechanical systems 

Electromechanical driven UTMs are by far the most common. They are driven by an electric motor and come in two main frame types: single column and dual column. Electromechanical systems are suitable for medium to heavy force testing applications. There are a number of accessories available to adapt them to a variety of uses, including environmental chambers, safety shields and safety chambers. They are often tabletop machines. 

Servo-hydraulic 

Servo-hydraulic driven UTMs are generally reserved for high-capacity testing applications in “heavy” industry and are capable of testing at very high forces. They use the principle of hydraulic force to move the crosshead. They are typically very large pieces of equipment.
