Case Study:

Medical Laboratory Test Fixture

Pentad designed, fabricated and installed a portable test fixture for use in a medical device laboratory. A PLC and touchscreen enable the user to control the system. The device measures flow rate and pressure of a Device Under Test (DUT) and under a wide range of test conditions.

Pentad designed and fabricated custom machined parts and along with off the shelf components assembled and tested the system. The test fixture was developed in concert with the client’s Quality System and the mechanical drawings were generated to ASME-Y14. Pentad wrote the Installation Qualification (IQ) Protocol, executed the Protocol and wrote the IQ Report.

Mechanical Design Services

Pentad Design provides product development and electromechanical packaging services. Services include the design of complex ruggedized military equipment, commercial avionics and telecommunications equipment.

All of our core staff has had the advantage of working at the "cutting edge" of the engineering profession and know how to apply that experience to complex mechanical design problems.

We take a unified approach to product design and development, allowing our clients to take full advantage of our multi-disciplinary team of engineers.

In addition to our highly experienced engineers and design specialists, we maintain close relationships with several technical specialists in related disciplines and with our fabrication vendors. We have the capability to help clients with the mechanical aspect of new product development – from mechanical design to assembly and system integration.
