Washer Load Cell 5kN 10kN Through Hole Force Transducer 20kN 30kN 50kN
Hollow Through Hole Load Cell FDBH is made of stainless steel based on strain gauge technology to deliver maximum 0.5% non-linearity of the rated capacity intended for both traction and compression force measurement. Washer Load Cell FDBH offers 0-5kN / 0-10kN / 0-20kN / 0-30kN / 0-50kN five rated measuring ranges to choose from. Hollow type load cell FDBH features a M30 threaded hole located at the center of the transducer, which offers following two mounting methods:
Donut type force sensor FDBH is very suitable for clamping/fastening force measurement, to meet requirements of different applications, model FDBH can also be modified or customized.

Washer Load Cell 5kN 10kN Through Hole Force Transducer 20kN 30kN 50kN
Output signal of load cell FDBH:
Load cell output: = (Power supply * Rated output) * Load / Capacity
Rated output of Hollow Load Cell FDBH is normally around 1.5mV/V.
Power supply of Washer Type Force Sensor FDBH is normally within 3-15V.
Load / Capacity is within 0-1.
So the output range of Clamping Force Transducer FDBH is normally within 0…+22.5mV.
Example one: Through Hole Load Cell FDBH-50kN with 1.5mV/V sensitivity powered by 10V DC,the output range is 0mV...+15mV.
Example two: Hollow Type Load Cell FDBH-10kN 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: Washer Type Load Cell FDBH-10kN working with amplifier FSC(0-10V)-24V,the Load-Voltage relationship will be 0-10kN compression force VS 0-10V output, which is linear regardless of the measurement error, 1V output corresponds to 1kN load, 2V output corresponds to 2kN force, and so on.
Thru-hole Loadcell FDBH 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
