SHQ-25 piezoelectric accelerometer is designed for long-term vibration monitoring of high-speed rotating machines such as aeroengines, gas turbine generators and the like.
It uses a symmetrical output form to eliminate power interference, electromagnetic noise and ground loop noise, especially suitable for industrial use. It has good heat resistance. High installation of resonant frequency and a wide range of frequencies.
Accelerometer with a stainless steel shell, all-welded gas-tight structure can therefore be used in humid, corrosive environments.
