# 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

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.influxtechnology.com/support_guides/technical-specifications/technical-specifications/k-series/k-iepe.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
