Through Hole Load Cell 500kg 1000kg Donut Washer Loadcell 2t 3ton
M36 threaded Pancake Load Cell FDBK is made of high stiffness alloy steel based on foil strain gauge technology to deliver 2.0mV/V rated output proportional to the applied force.Pancake load cell FDBK offers 0-500kgf / 0-1000kgf / 0-2000kgf / 0-3000kgf four rated measuring ranges with maximum 0.3% non-linearity of the rated output to choose from intended for both static and dynamic force measurement, low profile loadcell FDBK can be used for both tension and compression measurement, compact design makes it also suitable for in-line force monitoring. Force Sensor FCMA is designed with a M36*2 tapped hole running through the center of the transducer which can be used to mount attachments such as load buttons,eye bolts or other adapters for force loading, this makes spoke type load cells very adaptable to various cases, you may find pancake type load cell FDBK applicable for force measurement in injection-molding machines, press machines and material testing equipment, weight measurement for tanks, vessels and hoppers, and so on.

Brief instruction of Rated output(or Sensitivity):
Definition: The signal produced by load cell(or force transducer) when rated load is applied, expressed in terms of mV/V. The rated output indicates the output signal range of a sensor.
Sensor output = (Power supply * Rated output) * Load / Capacity
Rated output of through hole load cell FDBK is normally around 2.0mV/V.
Power supply of donut load cell FDBK is normally within 3-15V.
Load / Capacity is within 0-1.
So the output range of washer load cell FDBK is normaly within -30mV...+30mV for tension and compression force measurement.
Example one: Pancake Load Cell FDBK-30kN with 2.0mV/V power by 5V DC,the output range is -10mV...+10mV proportional to the applied load.
Example two: Universal Load Cell FDBK-10kN with 1.98mV/V power by 10V DC,the output range is -19.8mV...+19.8mV proportional to the applied load.
Load cell + Signal amplifier:
Load cell normally outputs -30mV...+30mV which sometimes cannot be recognized by signal processing units directly,so signal conditioner is introduced to convert mV signal into 0-5V/0-10V/4-20mA for easy signal processing.
Example: Compression load cell sensor FDBK-20kN working with -10-10V amplifier,the load-output relationship will be 0-20kN compression load VS 0-10V output, 0-20kN traction force VS 0-(-10V).
