Miniature Compression Load Cell 5kg 10kg 20kg Column Type Compression Sensor 30kg 50kg
A Force Sensor is a transducer that converts mechanical load into mV signal 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 load/force can be measured by measuring the output signal from the transducer.
Load cell output: = (Power supply * Rated output) * Load / Capacity
Rated output of Micro Pressure Force Sensor FFJ is around 2.0mV/V.
Power supply of Miniature Column Type Compressive Force Transducer FFJ is normally within 3-15V.
Load / Capacity is within 0-1.
So the output range of Miniature Compression Load Cell FFJ is normally within 0mV...+30mV for bidirectional force measurement.
Example one: Miniature cylindrical Compressive Load Cell FFJ-10kg with 2.0mV/V sensitivity powered by 5V DC,the output range is 0...+10mV.
Example two: Micro Column Type Push Force Sensor FFJ-20kg with 2.0mV/V sensitivity powered by 10V DC,the output range is 0...+20mV.
A signal conditioner can be used with force transducer FFJ to deliver -5~5V, 0-10V or 4-20mA output.
Example one: Miniature Compression Load Cell FFJ-5kg working with 0-5V amplifier,the Force-Voltage relationship will be 0-5kg compressive load VS 0-5V output, which is linear regardless of the measurement error. When you get 1V output, it means the current load is 1kgf push force, when you get 2V output, it means the current load is 2kgf pressure force, and so on.
Example two: Miniature Pressure Load Cell FFJ-10kg working with 4-20mA amplifier,the Force-Current relationship will be 0-10kg press load VS 4-20mA output, which is linear regardless of the measurement error. Namely 4mA output corresponds to “0” load, 5.6mA output corresponds to 1kgf press force, 12mA output corresponds to 5kgf compression load, and so on.
