General Input Sensor Node (SD-IN-2)

The General Input Sensors allow connection to existing diagnostic voltage or current output signals, creating a wireless solution for health monitoring in the most hard-to-reach, rugged locations.

General Input Sensor

What's New In Version 2?

Version 2.0 sensor nodes have twice the range, higher sampling frequency, and are two and a half times more robust than before. The sensors can easily transmit a higher density of data using DARTwireless and are powered by a standard CR123A camera battery. In a layout that can be configured for any plant or environment, as many as 100 sensor nodes can now send vibration data to each receiver. The sensors can be tuned to transmit data on the frequency you select, and monitoring bands can be customized to alarm levels that you choose, ready to caution or warn you immediately when frequency rises to a level you specify.

The SmartDiagnostics® Network

General Input Sensor Node role in Smart Diagnostics Network

RELIABLE MONITORING

General Input Nodes allow connection to existing diagnostic voltage or current output signals, creating a wireless solution for health monitoring in the most hard-to-reach, rugged locations. Each node communicates via a direct wireless link to a Primary Receiver Node, from which the data is imported into SmartDiagnostics® Software for viewing and analysis.

FLEXIBLE CONFIGURATION

The system is highly configurable and scalable and KCF can provide transducers to meet a wide array of applications. A system can have hundreds of sensor points, each of which can be configured to transmit data on a user-selected frequency, and unique indicators can be implemented to warn users of potential machine health issues.

COST EFFECTIVE

Easily installed without the downtime, expense, and labor costs of old-fashioned, hard-wired sensors. Simply place the sensors where you need them and within minutes they’ll transmit data. SmartDiagnostics® can predict failure before it occurs, saving money spent on unnecessary replacements and extending machine life. At the same time, energy costs are reduced, as properly maintained machines are more efficient.

Battery Life

The General Input Sensor Node is designed to be very energy efficient so that it can operate continuously for many years when powered by a 3 Volt battery.

The actual amount of power consumed (and therefore the effective battery life) is dictated by two factors:

  1. The frequency at which the sensor sends a heartbeat ping to the Base Station, and
  2. The frequency at which the sensor collects and transmits data to the Base Station.

The heartbeat ping takes very little energy so the primary driver of battery life is governed by the data collection frequency which you configure based on your business needs. The graph below illustrates how battery life varies with changes to collection frequency assuming the sensor heartbeats every four seconds.
