Chinese Name

CHINESE PAGE OF LANGUAGE Meggitt (Maryland), Inc. is the leading supplier of high performance sensing and vibration-monitoring solutions. Our range of Wilcoxon Research® accelerometers, 4-20 mA sensors, transmitters and instrumentation provide accurate and reliable vibration measurements for a wide range of markets and applications.

Wilcoxon Research Inc. was founded in 1960 by former staff members of the David Taylor Naval Research Center. It became a Meggitt company in 2004 and is now part of Meggitt’s Performance Sensing business, alongside other well-known names, such as Endevco® and Piezotechnologies.

For over 50 years our customers have trusted in Wilcoxon Research for:

• High performance products at affordable prices
• Solutions for every application
• Accuracy and reliability
• Total customer support

Our Germantown, Maryland facility houses a wide variety of modern manufacturing, assembly, and test equipment ranging from precision machinery for high-quality vibration sensor components to custom-built machinery specifically designed for accelerometer fabrication.

Parent company – Meggitt PLC

Headquartered in the UK, Meggitt PLC is an international engineering group specializing in extreme environment components and sub-systems for aerospace, defence and energy markets. It consists of five operating divisions and the Meggitt Maryland site is part of Meggitt Sensing Systems. Our world-class sensing capabilities include: condition-monitoring; air data systems and flight displays; inertial systems; and high performance sensors that measure virtually every physical parameter.

Timeline of pioneering advances at Meggitt (Maryland), Inc.

Meggitt engineers have been responsible for many advances in piezoelectric accelerometers. Some of our key accomplishments and milestones are listed below:

1960 Wilcoxon Research, Inc. is founded by a group of entrepreneurial scientists from the US Navy’s David Taylor Research Center (now the Naval Surface Warfare Center)

1961 First piezoelectric accelerometer to incorporate an integrally-isolated base, eliminating the requirement for frequency-limiting adapters

1963 Identified and specified the effects of base strain sensitivity and incorporated integral strain filters in compression-type models, while expanding lines of bending- and shear-type models which are immune to base strain

1964 Delineated and specified the magnetic and acoustic sensitivity of piezoelectric vibration transducer

1976 First ultra low-noise detection accelerometers for underwater applications

1981 Developed piezoelectric accelerometers with integral PIEZOFET™ with low noise charge amplifiers

1983 First piezoelectric velocity sensor and piezoelectric ultra-quiet seismic accelerometer

1990 Industry's first displacement output accelerometer

1996 First ultra high sensitivity, low noise seismic accelerometer for nano g measurements

1999 Formation of Wilcoxon Labs for leading edge research and development

2004 Meggitt PLC acquired Wilcoxon Research

2005 Developed a vibration transmitter series of products with the first customizable and field-programmable frequency response, powerful alarming capabilities, and digital communications

2006 ISO 14001 environmental management certification

2008 First stand-alone 4-20 mA vibration displacement sensor for machinery monitoring

2008 Developed an ocean-bottom, triaxial seismic accelerometer

2011 Changed legal name to Meggitt (Maryland), Inc. and began doing business as Meggitt Sensing Systems

2013 Introduced the industry’s only battery operated field reference source with 3 switchable frequencies to satisfy global markets

2013 Launched LPA 100T family (lower power accelerometer), MAC meter family (vibration meters), HT sensors (high temperature)

2014 Patented high isolation sensors capable of withstanding 6000 volts for use in wind turbine nacelles

2014 Launched VibraLink enclosures (VLS, VLD, VLT) with data ready indicator, 786LF family for low frequency applications, ReferenceMate (REF) handheld shaker kits

2015 First HART integrated sensor with three field programmable frequency bands

2015 Launched PCH420V Hart integrated velocity sensor with digital HART protocol, Vibration switch VSW-100 with adjustable alarm relays, HV high EMI resistant sensors
