Mini Flat Load Cell 500N 200N 100N Small Size Compression Force Sensor
Miniature Flat Load Cell FCFP is made of stainless steel based on strain gauge technology offering 100N / 200N / 500N three rated capacities intended for compression force measurement. Compact design with a mounting base makes it easy to install the transducer, 1000ohms high resistance minimizes the heat emission and improves long term stability. Miniature size enables button type load cell FCFP applicable for appliations where mounting space is limited. You may find Micro Flat Force Sensor FCFP suitable for applications such as load distribution analysis, mold pressure measurement, force overload protection, clamping force measurement, assembly force monitoring and so on.
A Load Cell is a transducer that converts force acting on it into electronic signal which is proportional to the applied force.The acting force causes deformation of the measuring element,the bonded strain gage deforms accordingly which will cause the resistance change of the wheatstone bridge,under constant power supply,the output signal between Sig+ and Sig- will change proportionally,thus the force can be measured by measuring the output signal from the load cell. Thin Flat Load Cell FCFP is designed to measure force in compression direction,outputs millivolt signal within 0~22.5mV, and signal amplification may be required for most applications, a load cell signal conditioner can be used to convert mV signal into -5-5V, 0-10V or 4-20mA output which is proportional to applied force.The amplified output then can be easily processed by PLCs and data acquisition software. The force can also be displayed through force indicator,force meter FPT is integrated with high accuracy/low noise 24 bit Sigma-Delta ADC,sampling speed up to 960Hz makes it suitable for both static and dynamic measurement;FPT also supports Modbus RTU protocol with RS485 or RS232 communication port,amplified signal 0-5V,0-10V,0-20mV or 4-20mA is also achievable from FPT.

Mini Flat Load Cell 500N 200N 100N Small Size Compression Force Sensor
Output signal of load cell and amplifier:
Load cell output: = (Power supply * Rated output) * Load / Capacity
Rated output of Button Type Flat Load Cell FCFP is normally around 1.0mV/V.
Power supply of Miniature Flat Force Sensor FCFP is normally within 3-12V.
Load / Capacity is within 0-1.
So the output range of Compression Type Force Sensor FCFP is normally within 0…+12mV.
Example: Micro Flat Load Cell FCFP-50kg with 1.0mV/V sensitivity powered by 5V DC,the output range is 0mV...+5mV.
The mV/V output from the wheatstone bridge sometimes can hardly be processed directly, a signal conditioner can be used with the load cell to deliver -5~5V, 0-10V or 4-20mA output.
Example: Button Type Flat Force Sensor FCFP-10kg working with amplifier FSC(0-10V)-24V,the Load-Voltage relationship will be 0-10kgf compression force VS 0-10V output, which is linear regardless of the measurement error, 1V output corresponds to 1kgf compression load, 2V output corresponds to 2kgf press force, and so on.
