Product catalog summary

Specifications:
The KST94C-4N and KST94C-9N sensors are designed for automated vibration measurement, particularly in quality control. They feature a movable tip guided by an air-damped piston/cylinder system, ensuring a linear frequency response through frictionless movement. The sensors guarantee reproducible results with constant tip pressure due to spring suspension, and they exhibit low distortion and environmental vibration sensitivity. They have a long life expectancy of over 10 million test cycles, an IP62 protection grade, and are oil-resistant. The sensors provide an IEPE voltage output with the probe tip electrically isolated from the body.

Technical Parameters:
The sensors operate on a piezo shear design with a voltage sensitivity of 100 ± 5% mV/g. The measuring range is ±20 g for KST94C-4N and ±40 g for KST94C-9N. The lower frequency limit is 40 Hz, while the upper frequency limits vary based on deflection and coupling conditions. The resonant frequency is greater than 6 kHz for KST94C-4N and greater than 7.8 kHz for KST94C-9N. The transverse sensitivity is less than 5%, and the wideband residual noise is less than 0.6 mg. The sensors have a maximum stroke of 5.5 mm and recommended deflection between 2 to 4 mm.

Environmental and Mechanical Characteristics:
The operating temperature range is 0 to 80°C with a temperature coefficient of -0.1%/K. The sensors weigh 120 g without cable and are made of stainless steel. They feature a UNF 10-32 socket and can be mounted using a clamp collar or M5x8 screw.

Accessories:
Suitable accessories include various IEPE cables and an adapter for connection purposes. The calibration adapter KST94_CA is used for calibrating the sensors with the VC120 vibration calibration system, suitable for frequencies from 100 Hz to 10 kHz.
