K-IEPE

INF2213

Our K-IEPE module is designed to connect IEPE sensors to a K-Box or K-AN8 voltage measurement device that normally cannot support IEPE sensors.

The powered K-IEPE module simply enables IEPE sensors to be connected via the BNC terminals and will output the signal voltages to the analog measurement device.

Calibration and sampling rates can be configured using the freely distributed K-Cal software.

Key Features

• Connects to the K-Series K-Box/K-AN8 via the Analog inputs

• Refresh rates achievable (4 channels 1kHz)

• ABS enclosure

Advantages

• Wide frequency range

• Linear amplitude characteristics in a wide dynamic range

• Ability to operate in severe ambient conditions (temperature, humidity, radiation and magnetic fields)

• High mechanical reliability and durability at the expense of moving parts in the sensor

• High vibration and shock resistance

• No need for other power supplies for sensors

• Compact structure and a large ratio of sensitivity to mass
