Spring Testers

CT Series (C Frame) Compression & Extension Spring Testers

The CT Series are Programmable Compression / Extension Servo Driven Spring Testers. This Family of Testers is constructed with a C Frame design. Please see the following link for specifications.

Here you can see a video of the tester

CT Series (C Frame) Compression & Extension Spring Testers

CT Series (H Frame), High Capacity Compression & Extension Spring Testers

The CT Series are Programmable Compression / Extension Servo Driven Spring Testers. This Family of Testers are constructed with a H Frame design using either 2 or 4 ballscrews.

CTMS Series (Manual Testers)

The CTMS  Series are manual  Compression / Extension  Spring Testers.  This Family of Testers are divided into two distinct models; standard models and PC models.

T Series Torsion Spring and Bar Testers

The T Series are Programmable  Servo Driven Torsion Spring Testers with two interchangeable torque cells per tester.

ALT Series (Automated modular spring testing systems)

The ALT Series System is an automated modular spring tester, setter and sorter with the following characteristics:

Actuator and valve testers

Actuators and valves are used in different industries like oil, gas and water. This rig tests actuators and valves, shows the torques results and creates reports with R&R data. This is a summary of the characteristics of these test rigs:

  • Tests pneumatic double acting and single acting valve actuators
  • Tests and quantifies torque to open and close valves
  • Fully maps the torque/angle opening and closing characteristics
  • Multiple load cell capability up to 2000Nm torque
  • Valve and actuator connections conform to ISO5211 standard
  • Fully programmable test envelopes, can be saved and used per part number
  • Data captured can be opened directly in Microsoft Excel for post processing
  • Software compatable with Microsoft Windows XP, 7 and 8
  • Includes full self calibration hardware and software
Force Testers

SAS produces force testers for several applications; of course for testing the load of springs but also for bottle cap openers. The testers are custom made. If you have a requirement to test a load, please contact us.
Some examples are shown on this site.

Damper Tester

This damper tester is the latest development. It dynamically tests Shock absorbers or gas springs up to 50000N. The mounting is adaptable to test several dampers simultaneously.

The technical specifications are summarized below:

  • 2 load cells to inspect 2 parts simultaneously
  • Maximum test speed of 180mm/s
  • Maximum load for each load cell 2500N with a total combined load of 5000N
  • Programmable for both forward and reverse travel directions
  • At each tolerance point the speed of travel can be changed dynamically from 0.01mm/s up to 180mm/s
  • The machine can interface and be controlled by a PLC for in-process inspection
  • Results can be recorded and loaded into Excel for analysis
  • Tolerance curves can be designed in Excel and imported into the CT5000HS program

Profile: SAS Inc.

Spring Analysis Systems (SAS Inc) was established in 2001 by Larry Sheiman and Martin Somers, Both of whom are Aeronautical Engineers with a very strong background in the Hi-Tech Industry.

SAS Inc exhibited their first products in 2002 at CASMI in Chicago. These products included the world’s first spring tester that is entirely controlled by a pocket PC.
Only a few years later SAS Inc exhibits an entire range of equipment which included five families of products. These product families include the various models of compression, tension and torsion testers, life cycle and fatigue testers and the latest line of vision inspection equipment for both axi-symmetrical parts and for 2 and 3 D wire forms.
Although SAS Inc initially developed its products to serve the Wire and Spring Industry, other industries have successfully adapted these product families for a multitude of applications.
SAS Inc’s creativity in its in-house software development has enabled its equipment to serve a large spectrum of industries from the space industry through the automotive industry to the medical industry.
