November 30, 2011 - Meggitt introduces 712F-M4 and the 997-M4 side exit accelerometers with metric mounting. The compact sensors care apable of continuous submersion and high frequency monitoring. The 712F-M4 and 997-M4 have the capability of monitoring in low clearance areas. The captive screw design with a safety wire hole adds additional protection in underwater applications to ensure the sensor cannot become dislodged. More compact and lighter than the company's general purpose or low frequency accelerometers, the 712F-M4 and 997-M4 are usable on smaller, lighter structures without fear of mass loading, ensuring the sensor will not alter the vibration of the structure.
The integral cable design that uses a proven glass to metal seal technique assures true hermetic sealing providing a 100 psi tested seal. This superior cable attachment technique has proven itself as one of the best methods for guaranteeing long term underwater exposure. The 712F-M4 houses a general purpose 100 mV/g vibration sensor with ±10% sensitivity, and operates from 3 Hz to 25 kHz. The 997-M4 comes with 10 mV/g output with ±5% sensitivity and a frequency range that extends down to 0.5 Hz.
The 712F-M4 and 997-M4 are suited for the harshest industrial environments. The accelerometers follow the rugged, hermetically sealed, ESD protected and EMI/RFI shielded format that has made Wilcoxon Research sensors the standard in many plants worldwide. Integral cable design and corrosion resistant construction make both sensors capable of continuous submersion in harsh and wet environments. 712F-M4 and 997-M4 are appropriate for most machinery monitoring applications such as gear mesh frequency or early bearing wear detection. Machine tool spindles and high speed compressors also benefit from the high frequency capability of these sensors.
