Selection Guide for film pressure sensors:

1. determine the size of the application scene

2. determine the total pressure applied

3. sensitive area size of selected sensor

4. calculation of the ratio of the force surface to the two force contact surfaces of the sensor.

5., according to the ratio of third obtained by second total pressure, we can get the maximum pressure that the sensor sensitive area may bear, and select the sensor range.

6. sensor model example: RFP 601-1kg:

RFP: for the name of the trademark and the type of sensor

601: the size code for the selected sensitive area

1kg: for the range of the sensor, it represents the maximum measurable pressure value.

The RFP thin film bending sensor can make static and dynamic measurements of any contact surface pressure.

The curved sensor converts the pressure of the sensor induction region into the resistance signal, and then according to the force.

The calibrated relation curve of the resistance gets the change information of the external pressure, the greater the pressure, the sensor loses.

The smaller the resistance is.

Matters needing attention

The RFP thin film pressure sensor is a surface sensor. Therefore, when using, try to make the load even and avoid sharp objects contacting the sensor directly. In addition, the sensor can bend any angle to both sides, but it can't bend.

Eumbo has a core patented technology for flexible thin film tactile pressure sensors.

The thickness of the sensor is only 0.1mm-0.2mm, and the flexibility is very good, so it is used to measure all kinds of contact surfaces.

The pressure created better conditions. Compared with the traditional methods of measurement, this is a kind of classics.

Economic, efficient, accurate, rapid, intuitive, convenient pressure distribution measurement tools.

The standard RFP pressure sensor consists of two thin film of polyester and two thin films.

Table - laying conductors and semiconductors. When the external force acts on the sensing point, its resistance will follow the external force.

When the law changes and the pressure is zero, the maximum resistance is, the greater the pressure is, the smaller the value is. Through the difference

Different density of sensor points are placed in the place where different spatial resolution can be achieved. Different

The area and spatial resolution of the sensor can meet various measurement requirements
