Product catalog summary

Specifications Overview
The KST94C-4N and KST94C-9N sensors are designed for automated vibration measurement, particularly in quality control. Key features include a movable tip guided by an air-damped piston/cylinder system, a linear frequency range due to frictionless movement, and a constant tip pressure ensured by spring suspension for reproducible results. These sensors offer low distortion, low environmental vibration sensitivity, and a long life expectancy of over 10 million test cycles. They are IP62 rated and oil-resistant, with an IEPE voltage output and an electrically isolated probe tip.
