Meggitt Sensing Systems (Germantown, MD) introduces two new Wilcoxon Research side exit accelerometers with metric mounting. The 712F-M4 and the 997-M4 are compact sensors capable of continuous submersion and high frequency monitoring. The side exit 712F-M4 and 997-M4 have the capability of monitoring in low clearance areas. The captive screw design with a safety wirehole adds additional protection in underwater applications to ensure the sensor cannot become dislodged. 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.
