About Stewart Ergonomics, Inc.

Stewart Ergonomics, Inc. was founded to design and manufacture No Touch Safety Controls and SLAM DUNK® precision dry leak detectors. It evolved from Stewart Enterprises, Inc., which was created in 1974 as a manufacturer of specialty machiner,. providing custom design and construction of a wide variety; specializing in automatic assembly, drilling, and leak testing machinery.

In 1982, a project required a custom relay logic two-hand, no tie down control and the process for the development of our current No Touch System was born. By 1991, work progressed to the development of a low-force switch for use by the handicapped. In 1992, further developed into “No Touch” and became 100% solid state. By 1996, Stewart Ergonomics, Inc. assumed all responsibility for research and development design & manufacture, testing, and marketing of these unique Ergonomic® Two-Hand No TieDown Controls under Patent No. 5,451,770.

By 2002, having continued to manufacture a number of precision leak testers, we introduced our all digital Slam Dunk®, the clean, dry leak tester, reading to .0001 p.s.i. working to .00001 p.s.i in the current pressure range of .1 to 1000 p.s.i Several features are patent pending.

Both products are available through our distributor network.

Certifications & Standards

We at Stewart Ergonomics, Inc. have designed and tested our complete line of ERGONOMIC® controls to a variety of OSHA, ANSI, UL, CSA, and CE standards.
Although OSHA does not certify anything, they issue standards; we design and test our products to meet them. We have designed and tested in-house to meet OSHA 1910.212, 1910.217, and ANSI Z8,1-1990. In addition, ANSI B11.2-1995 is covered by our Option 14. Our model 12-3002-04 with Option 26 (Ross safety valve) or Option 27 (Herion Cross Flow Sivex Double Valve Series XSZ) also complies with ANSI B11.1-1988 and B11.19-1990 for control monitoring, but requires a clutch brake monitor for full mechanical press compliance. Option 14 in an integral part of our new 3000 series of CE mark and UL 491 tested controls.

We have contracted the with Canadian Standards Association (CSA) to certify our controls to the following:

ANSI/UL 347 High Voltage Industrial Control Equipment 2000 & 3000 Series
ANSI/UL 508 Industrial Control Equipment 2000 & 3000 Series
CAN/CSA - C22.2 No. 14-95 Industrial Control Equipment 2000 & 3000 Series
CAN/CSA - C22.2 No. 94-M91 Special Purpose Enclosures 2000 & 3000 Series
UL Std. No. 50 Enclosures for Electrical Equipment 2000 & 3000 Series
UL Std. No. 491 Machinery Control Specification 3000 Series Only
CE Mark 3000 Series Only

The above certifications except UL 491 were received by Stewart Ergonomics, Inc. in May, 1997. The CSA logo on our controls has directly beneath it the letters C US, which indicates that they are tested to UL specifications. The -C designates that the Ergonomic® control meets Canadian specifications also.

CE mark declaration for Series 3000 controls was made in the fourth quarter of 1998 after six months of testing and evaluation in-house and at CSA. UL 491 and CE units were tested to meet many stringent criteria. A partial listing follows:

EMI Testing included but was not limited to:

Fast transit test - Tested at 1500V for 200 milliseconds
Spark Gap testing
Electrostatic Discharge testing - Tested between 4 - 20,000V
Field strength - Tested at 10V per meter, with constant and sweep frequency

Mechanical testing included shock and vibration, and shorting every pin of every electronic device without causing an output. It also involved opening every pin of every device without causing an output.

Every control is production tested 5000 times over 11 hours.

With the above testing, the ERGONOMIC® control, is the most thoroughly tested two hand control in the world today! Combined with the affordability, size, and versatility of this product, it is the most cost-effective means of protecting your employees.

STEWART ERGONOMICS IS PROUD TO ANNOUNCE

IT'S A DIGITAL SLAM DUNK®

Make Your Pressure Testing a SLAM DUNK® The Clean, Dry Leak Tester

SLAM DUNK® is a high performance control, which is easy to master in minutes. Set up consists of following the prompts on the 80-character display and entering simple parameters by pressing the four control buttons. These buttons are password protected to prevent unauthorized changes. Test programs can be linked to run sequentially for parts requiring multiple tests. The test is started by manually or remotely activating the start button. A typical test consists of fill, dwell, and snapshot, compare and depressurize cycles. A bright red or green LED indicates results of the completed test with +24 sourcing output provided for PLC.

Typically, a 7 micron leak in a 15 cu. in. test part can be passed or failed in 5 seconds @ 10 p.s.i., and in a 125 cu. in. test part in 15 seconds at 10 p.s.i. 2 sccm leaks are typically found at 100 p.s.i. in less than 15 seconds at a volume of .6 liters. Vacuum testing down to -14.7 p.s.i. can simplify fixturing of molded parts and is necessary for components of vacuum systems.
