Our waterproof accelerometer range includes our MM273A series (PE Mode) and our MM173A series (IEPE Mode). These accelerometers are completely waterproof and designed to withstand high humidity and underwater environmental vibration testing. Each model features an integral waterproof cable, capable of operating at depths of up to 100 metres.
Features and Benefits of our Waterproof Accelerometers:
Completely Waterproof: Designed for use in submerged conditions, these accelerometers can withstand depths of up to 100 meters.
High Sensitivity and Low Noise: Provides precise and reliable vibration measurements.
Robust Construction: Made from 316L stainless steel with welded sealing, ensuring durability and longevity.
Integral Waterproof Cable: Ensures seamless operation without the risk of water ingress.
Operation:
Our Waterproof Accelerometers operate using a piezoelectric ceramic element. When subjected to vibration, the ceramic element generates an electrical charge proportional to the mechanical stress. In the PE Mode models, this charge is then transmitted through an integral cable. In the IEPE Mode models, the charge is converted to a low-impedance voltage signal for easier handling and data acquisition.
