OEM Wireless Accelerometer SensorThe OEM wireless accelerometer can be used in a host of applications where knowing impact, vibration, inclination, etc. is required. Please review the profile definitions below to select the one that best meets your need. Should one of the profiles not meet your needs, please contact OEMSensors.com with your requirements at devteam@oemsensors.com and they will be reviewed for supportability. All sensor data is securely transmitted through an OEM wireless gateway to the iMonnit Online Sensor Monitoring software where it is stored and viewable from any web enabled device. The iMonnit online software system is completely white label (private brand) capable, allowing you to offer the online monitoring service as your own. Email and SMS text messages can be configured through the online system to alert users immediately when a defined parameter has been met or exceeded. « Learn more about OEM online monitoring software OEM wireless accelerometers are available in three profiles. The profile tells the sensor what to report to the software. Based on your needs, please specify the profile type at the time of order otherwise you will receive Profile 1. Profile 1: Tilt - Accelerometer activates at a set time interval (defined by user) and measures g-force along X, Y and Z axes. Primary use is as an inclinometer or tilt sensor. There are three operating modes, ±2 G, ±4 G, or ±8G. The data displayed is the g-force on each axis, e.g. –> X: 0.001 Y: 0.031 Z: 1.01. Profile 2: Motion Over Time - Accelerometer samples at 800 Hz over a 10 second period, and reports the measured MAXIMUM value for each axis in g-force and the AVERAGE measured g-force on each axis over the same period, for all three axes. (Requires AA power source, coin cell battery will not support the power requirements.) This sensor reports in every 10 seconds with this data. Other sampling periods can be configured , down to one second and up to 10 minutes*. The data reported is useful for tracking periodic motion. Sensor data is displayed as Max X: 0.125 Max Y: 1.012 Max Z: 0.015 Avg X: 0.119 Avg Y: 1.005 Avg Z: 0.007. * Customer cannot configure sampling period on their own. They will need to contact OEMSensors.com to reset the period to be monitored. Profile 3: G-Force Impact – Accelerometer activates when g-forces are exceeded by a user defined threshold – up to 8 g-force. The user can key in the desired threshold for the g-force trigger. This sensor has two operation modes that can be also selected by the user: High Performance and Low Power. High Performance has an output data rate of 800 Hz with the High Pass Filter cutoff at 16 Hz while the Low Power has an output data rate of 12.5 Hz with the High Pass Filter cutoff at 0.25 Hz.

* Actual range may vary depending on environment. |
