Product catalog summary
Specifications:
The document details the specifications of two triaxial accelerometers, KS813B and KS823B. Both models feature an IEPE output and are designed with a shear piezo system. The KS823B is noted for its high sensitivity, low frequency limit, and very low noise, making it suitable for sensitive measurements in buildings and wind turbines. Both models are waterproof to IP67 standards.

Mechanical and Electrical Properties:
The KS813B has an insulated base to prevent ground loops and features a central drilling for mounting. The KS823B includes a mounting adapter for 360° axis alignment. The voltage sensitivity for KS813B is 100 ± 5% mV/g, while for KS823B it is 500 ± 5% mV/g. The destruction limit for KS813B is 4000 g and for KS823B is 2000 g.

Frequency and Noise Characteristics:
The linear frequency range for the z-axis varies between the models, with KS813B ranging from 0.2 to 10000 Hz and KS823B from 0.07 to 6000 Hz. The resonant frequency for KS813B is greater than 15 kHz and for KS823B is greater than 9 kHz. Noise densities are provided at various frequencies, indicating lower noise levels for KS823B.

Environmental and Mechanical Data:
Both models operate within a temperature range of -20 to 90°C for KS813B and -30 to 90°C for KS823B. The protection grade is IP67, and the case material is stainless steel. The weight without cable is 115 g for KS813B and 365 g for KS823B.

Mounting and Accessories:
Various mounting accessories are available, including magnetic bases and mounting pads for different applications. The KS823B can be attached to walls and ceilings using a mounting pad and coupling ring for axis alignment. Accessories include IEPE cables, adapters, and mounting hardware.

Ordering Information:
The document provides ordering details for the KS823B, including a sensor with an accessories kit and a separate data sheet option.
