What are the disadvantages of using sensors?
Advantages are their accuracy, low cost, and high performance etc. Disadvantages are that they can be affected by environmental changes and contamination, e.g., a gas that they are measuring can affect the performance of the sensor [5].
How sensitive is a flex sensor?
The Flex Sensor is a unique component that changes resistance when bent. An unflexed sensor has a nominal resistance of 10,000 ohms (10 K). As the flex sensor is bent the resistance gradually increases. When the sensor is bent at 90 degress its resistance will range between 30-40 K ohms.
Why are flex sensors so expensive?
Why are flex sensors so expensive? It becomes too costly to build a control system for both hands as one will cost around INR 600–900. The soldering on flex sensor is difficult. Will produce errors when used for a long time due to change in the flexibility of the sensor.
What are three advantages of using sensors in different applications?
Advantages of Sensors
- Accelerate processes and make them more accurate.
- Collect process and asset data in real time.
- Monitor processes and assets accurately, reliably, and continuously.
- Increase productivity and reduce total cost of ownership.
- Lower energy wastage.
What are the advantages and disadvantages of smart sensors?
1) In wired smart sensors, complexity is much higher as a consequence the cost is also high. 2) Required use of predefined embedded function during the design of the smart sensor. 3) It requires both actuators and sensors. 4) Sensor calibration has to be managed by an external processor.
What are flex sensors used for?
A flex sensor is a kind of sensor which is used to measure the amount of defection otherwise bending. The designing of this sensor can be done by using materials like plastic and carbon. The carbon surface is arranged on a plastic strip as this strip is turned aside then the sensor’s resistance will be changed.
How does flex sensor work?
As a variable printed resistor, the Flex Sensor achieves great form-factor on a thin flexible substrate. When the substrate is bent, the sensor produces a resistance output correlated to the bend radius—the smaller the radius, the higher the resistance value.
What is the advantages and disadvantages of industrial sensors?
