Film Pressure Transducer | High Resistance Force Sensor | 20g to 2kg Range

This thin film pressure sensor changes its electrical resistance when you press on it. It measures force from a light touch (20g) up to 2kg, making it useful for many different DIY projects. Features and Benefits - Thin and bendable - You can curve it or fit it into small spaces. - 20g to 2kg measurement range - It detects both small and larger forces. - Simple resistance output - This sensor acts like a variable resistor, so it's easy to connect to an Arduino or other microcontrollers. - Sensitive to small forces - It reacts to slight pressure changes, which is good for applications needing exact force feedback. Applications - Robotics - Gives a robot's gripper a sense of touch to control how tightly it holds things. - Smart Devices - Make custom buttons or controls that respond to pressure. - Bed Monitoring - Build a system to check if someone is in a bed or chair, or if they're moving. Safety & Preparation Before connecting or testing any pressure transducer, ensure all power sources are disconnected. Work in a clean, dry environment to prevent damage to the sensor or electrical components. Pressure transducers, like this Film Pressure Transducer, convert physical force into an electrical signal. Understanding how pressure transducers work is key to safe operation. This particular High Resistance Force Sensor is designed for a Measurement Range of 20g to 2kg, so avoid applying forces outside this range during testing to prevent damage. Check Excitation Voltage The correct excitation voltage is crucial for the accurate operation of any pressure transducer. While this product's specific voltage is not provided, many pressure transducers operate on 5V, 10V, or 24V. Consult the sensor's datasheet or your system's requirements for the precise voltage. Applying an incorrect voltage can damage the transducer or lead to inaccurate readings. Always verify the voltage with a multimeter before connecting to the sensor. This step ensures the transducer receives the power it needs without being overstressed. Test Output Signal (Zero Pressure / No Load) To understand how pressure transducers work, first establish a baseline. With no pressure or force applied to the Film Pressure Transducer, measure its output signal. For this High Resistance Force Sensor, the Output Type is Resistance. You should measure the resistance across the output terminals. This "zero-pressure" reading is your starting point and confirms the sensor is functional before any load is applied. Comparing this to the transducer's specifications helps verify its calibration and ensures it is ready for use within its 20g to 2kg Measurement Range. For Current Output Transducers (4–20 mA): Although this specific Film Pressure Transducer has a Resistance Output Type, many pressure transducers provide a current output, typically 4-20 mA. To test these, connect a multimeter in series with the output loop. With no pressure applied, the output should ideally read 4 mA. As pressure increases within the transducer's specified range, the current should increase proportionally, reaching 20 mA at the maximum rated pressure. This linear relationship is how these pressure transducers work, providing a robust signal for logic controllers. For Voltage Output Transducers (0-5V, 0-10V, or mV): While this Film Pressure Transducer uses a Resistance Output Type, many pressure transducers provide a voltage output, such as 0-5V, 0-10V, or a millivolt (mV) signal. To test these, connect a multimeter in parallel across the output terminals. With no pressure applied, the output should read 0V (or the specified zero-pressure voltage). As pressure increases to the maximum of the transducer's range, the voltage should increase proportionally to 5V, 10V, or the maximum mV output. This is how these pressure transducers work, providing a clear analog signal.
