Force Sensitive Resistor IMS-S40 (50KG) Force Sensor 40mm

The principle of the pressure sensor test is to apply the stress applied in the sensing area of the sensor film into the change of the two-line resistance value, and obtain the external stress change information according to the calibration curve of the stress-resistance. The greater the stress, the lower the sensor output resistance.

Scope of application

Can be used for geotechnical engineering triaxial test earth pressure test, sample pressure distribution test, bionic robot foot under the ground sensing, mammalian bite force test biological experiments and other industrial fields.

Features

• Model: IMS032-S40
• Sensitive Area Diameter: 40mm 
• Measuring Range: 2kg – 50kg
• Lead wire: 100mm
• Material: PE insulating plate 
• Operating Principle: Transform the stress exerted on sensitive area into two-line resistance variation; according to the declared relationship between the stress and resistance can obtain stress changing information from outside; the more the stress is, the lower the sensor output resistance 
• Applications: Test soil pressure measurement, test material pressure distribution measurement (not recommend to use in fields which needs to teat precise pressure)

These sensors are simple to set up and great for sensing pressure, but they aren't incredibly accurate. Use them to sense if it's being squeezed, but you may not want to use it as a scale.
