Micro Washer Load Cell 1kN 500N 200N 100N 50N Donut Force Sensor
Miniature Donut Load Cell FDBF is made of stainless steel based on strain gauge technology to deliver maximum 0.5% non-linearity of the rated capacity. Small size donut load cell FDBF offers 0-50N / 0-100N / 0-200N / 0-500N / 0-1000N five rated measuring ranges to choose from.Washer type load cell FDBF features a 6.6mm hole locates at the center of the transducer, so the load structure can pass through the sensor, which makes hollow force transducer FDBF an excellent option for tightening and clamping force measurement.Forsentek can also provide custom made service for the donut type load cells.

Micro Washer Load Cell 1kN 500N 200N 100N 50N Donut Force Sensor
Output signal of load cell FDBF:
Load cell output: = (Power supply * Rated output) * Load / Capacity
Rated output of Micro Hollow Load Cell FDBF is normally around 1.5mV/V.
Power supply of Washer Type Force Sensor FDBF is normally within 3-15V.
Load / Capacity is within 0-1.
So the output range of Clamping Force Transducer FDBF is normally within 0…+22.5mV.
Example one: Miniature Through Hole Load Cell FDBF-5kg with 1.5mV/V sensitivity powered by 10V DC,the output range is 0mV...+15mV.
Example two: Micro Hollow Type Load Cell FDBF-10kg with 1.5mV/V rated output powered by 5V DC,the output range is 0mV...+7.5mV.
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 0~5V, 0-10V or 4-20mA output.
Example: Micro Washer Load Cell FDBF-50kg working with amplifier FSC(0-5V)-24V,the Load-Voltage relationship will be 0-50kg compression force VS 0-5V output, which is linear regardless of the measurement error, 1V output corresponds to 10kg compression load, 2V output corresponds to 20kg press force, and so on.
Loadcell FDBF can also work with digital indicator FPT to deliver below functions:
-Display force value in real time
-Peak holding to grab the maximum force during testing
-RS485 or RS232 interface
-0-5V/0-10V/4-20mA analog output
-Switch output
