Sensor drift characteristic testing
Embodiments of apparatuses, articles, methods, and systems for measuring sensor drift characteristics are generally described herein. In some embodiments, a system having a sensor platform to receive a sensor and measure drift characteristic of the sensor is disclosed. The system may further include a data acquisition device coupled to the sensor platform to receive the measured drift characteristic and to compare them to acceptance criteria in order to determine an acceptability of the sensor. Other embodiments may be described and claimed.
1. A system comprising:
a sensor platform to receive a sensor and to measure drift characteristics that quantify a change from a first response of the sensor, to a first stimuli at a first time period, to a second response of the sensor, to a second stimuli at a second time period, the first stimuli being at least approximately equal to the second stimuli; and
a data acquisition device coupled to the sensor platform to receive the measured drift characteristics of the sensor, to compare the measured drift characteristics to acceptance criteria, to determine acceptability of the sensor based at least in part on said comparing of the measured drift characteristics to acceptance criteria.
2. The system of claim 1 , wherein the sensor is a first sensor and the sensor platform is to simultaneously receive a plurality of sensors including the first sensor, and to measure the drift characteristics of the plurality of sensors.
3. The system of claim 2 , wherein the data acquisition device is to compare the measured drift characteristics of the first sensor to acceptance criteria based at least in part on the measured drift characteristics of the plurality of sensors.
4. The system of claim 2 , wherein the sensor platform further comprises:
one or more boards having a plurality of sockets configured to receive the plurality of sensors.
5. The system of claim 4 , further comprising:
a sensor platform to simultaneously receive a plurality of sensor and to measure drift characteristics of the plurality of sensors over a time period;
a data acquisition device coupled to the sensor platform to receive the measured drift characteristics of the plurality of sensors, to compare the measured drift characteristics to acceptance criteria, and to determine acceptability of the plurality of sensors based at least in part on said comparing of the measured drift characteristics to acceptance criteria; and
a signal converter to receive output from the plurality of the sensors in a first format and to convert the received output to a second format.
6. The system of claim 5 , wherein the sensor platform further comprises:
one or more boards having a plurality of sockets configured to receive the plurality of sensors; and
a selection mechanism to selectively couple output received by each of the plurality of sockets to the signal converter.
7. The system of claim 5 , wherein the data acquisition device is to compare the measured drift characteristics of the first sensor to acceptance criteria based at least in part on the measured drift characteristics of the plurality of sensors.
8. The system of claim 1 , wherein the drift characteristics include at least sensitivity drift, settling drift, and/or output drift.
9. The system of claim 8 , wherein the drift characteristics include at least sensitivity drift and settling drift.
10. The system of claim 1 , wherein the data acquisition device is to calibrate the sensor based at least in part on the measured drift characteristics.
