Force sensors or load sensors come in three main categories. First, tension sensors measure straight-line force in opposite directions away from each other; this is considered a positive force. Compression sensors measure straight-line force in opposite directions toward each other; this is called negative force. Third, shear sensors measure either tension or compression along askew directions, where the two forces are not in line with each other.
When comparing various force sensors, consider the measurement range and accuracy. Displacement of physical elements usually determines the force. Calibration force sensors associate force with deflection. Some of the basic elements that perform force sensing are S-beam, washer, platform, link, bolt, cantilever, load pin, tank weighing and several others. The main output categories are analog current, frequency or voltage, as well as series or parallel. There is also the force sensor switch.
Here are some of the main types of force sensors:
1. Sensor chips are basic force sensors.
2. Transducers are complex and provide an output.
3. Meters or instruments typically have displays and often process or condition signals.
4. Indicators or gauges have displays but no outputs.
5. Recorders track force measurements over time.
Purchase force instruments from sources with broad selectionsThere are a lot of parameters for calibration force sensors, force gauges, a force sensor switch and other force sensing technologies. Shopping sources with large selections may mean looking through more products, but it will also help you find the best fit for your application. Also, look for sources that provide good technical data and support to help you buy force sensor technology.
Find specialty force sensor distributorsFor very specialized types of force sensors, sometimes it's best to find a company that concentrates on niche products.
Get the best information on the latest force sensor technologyFor many applications, there's more than one way to get the job done. Take a quick look at some of the newest technologies to see if there's a product that exceeds your expectations.
- If there's a chance that temperature will cause errors in your force measurements, use a temperature compensated force sensor.
