  • 𖤼【Static/Dynamic Pressure Sensing】RP-C Resistive Pressure Sensors are flexible thin-film sensors whose resistance value decreases as the pressure acting on the sensing area increases.
  • 𖤼【Fast Response Time】The P-C Pressure Sensor is a cutting-edge force-sensitive resistor that provides a fast response time of less than 10 milliseconds. With a slim profile of 0.4 mm, this thin film pressure sensor is ideal for projects and other applications that require accurate pressure measurements in the 20g to 2kg range.
  • 𖤼【Long Durability Life】The RP-C force sensor is designed to last for more than one million cycles, ensuring stable performance with less than 3% resistance variance. It is highly sensitive, triggering at only 20g of force, and can be designed for use in harsh environments such as waterproofing, and operating temperatures of -40°C to 120°C.
  • 𖤼【Wide range of applications】The flexible design of this force transducer with static or dynamic pressure modes allows for a wide range of applications. Used in bed monitoring, sleep monitoring, smart shoes, smart switches, counters and medical devices, it is suitable for industrial automation, medical devices, automotive electroni
  • 𖤼【Excellent Material】RP-C resistive sensor is made of high-quality material and adopts ultra-thin design, which can be lightly installed in various equipment and systems with good durability and stability.


Product Description

Film Pressure Sensors

Two quantity packages available

Excellent mechanical properties of the polyester film, the top layer is a flexible film and composite on the top of the pressure-sensitive layer, the bottom layer is a flexible film and composite on the top of the conductive lines, when the inductive area is under pressure, the lines disconnected from each other in the bottom layer will be through the top layer of the pressure-sensitive layer conduction, the port of the resistance of the output value with the pressure change

Suitable fixed resistance

The above graph shows the high linearity of the coordinate values after the log log10 process

.

Voltage divider

The sensor is connected in series with a fixed resistor and the output voltage across the fixed resistor is measured. vout=Vcc*RO/(RO+Rs) In general, the fixed resistor is recommended to be 1/3 to 1/2 of the applied resistance range of the sensor.

There are

Suitable fixed resistors can give a degree of approximate linearity between pressure and output voltage over a range of pressures. Depending on the required resistance value of the measuring resistor, an operational amplifier can be added after the voltage divider

Film Pressure Sensors

Wide range of applications

Our brand specialises in the industrial category, our aim is to provide you with high quality industrial and commercial tools and accessories. Meet your daily industrial and commercial use needs and provide you with satisfactory utilisation, if you don't know which thin film pressure sensor to choose, please choose us Ezweiji.

  • Not suitable for calculations of absolute, specific values, but only for estimations by means of estimates, values provided by examples, not suitable for precision applications

  • The exact accuracy depends on the usage scenario, the contact area/material to be pressed on, and so on. For more accuracy, please calibrate the pressure and output according to your actual application.

  • Provide 51 microcontroller / ARDUINO / STM32F103 microcontroller routines

  • Most people choose 6kg or 10kg is already enough, not all the weight of the human body weight on the sensor above, there are a few kilograms enough, timing the human body are pressed in this sensor, will not damage the sensor!

  • Considering that each customer does not need the quantity demand, we specially packaged 4 tablets of specifications to meet the needs of different customers, to do a preferential price!

It would be nice if the manufacturer had published links to sketches for these. However, you can search yourself and find examples from the likes of Adafruit and others.Fairly good linearity in response curve, but again, you aren't going to force calculation, but merely approximation or presence of a force change. For our use, we needed to detect when someone sat in a chair and also when they got up. These devices aren't really meant to detect the weight of a human body, but they do just fine as we found.Good price... two mylar packs with two sensors in each pack.
