Dear Ahmed, you can also use the BH-type loadcell, just make sure that the bandwidth covers a very low frequency (some as low as 0.1 Hz). 

Thank you.

What about S type ?

Can i use this ?

Hello Ahmed,

I am a bit doubtful about the S-type loadcell you are intending for such a high load with dynamic frequency of 1.5Hz. It may not a solution for long-term usages. I would rather suggest to use a LVDT type extensometer for such fast rate.

Omega Model DLC101-5000 covers the frequency range of 0.08 Hz -25kHz

Dear Dr. Ahmed Hesham

From my experience in force and torque measurements, there is no dependency between the force transducer type, S-type or other, and the dynamic response. Actually there are dynamic force transducers (you can find some of them on this link-http://www.hbm.com/en/menu/products/transducers-sensors/force/) and you should know that to measure dynamic force you should have not only dynamic force transducer but also dynamic data acquisition system (here you can find one-http://www.hbm.com/en/menu/products/measurement-electronics-software/high-speed-data-acquisition/).

according to vibration principle:

(https://www.novatechloadcells.co.uk/resources/dynamic-force-measurement)

Force input frequencies up to one-tenth of the mass systems' natural frequency yield measurement errors of less than 1%.

so you should choose a load cell with a natural frequency above 15 Hz to measure this force behavior

Dear Ahmed,

A load cell is a type of transducer, specifically a force transducer. It converts a force such as tension, compression, pressure, or torque into an electrical signal that can be measured and standardized. As the force applied to the load cell increases, the electrical signal changes proportionally. The most common types of load cell used are hydraulic, pneumatic, and strain gauge. Every load cell is subject to "ringing" when subjected to abrupt load changes. This stems from the spring-like behavior of load cells. In order to measure the loads, they have to deform. As such, a load cell of finite stiffness must have spring-like behavior, exhibiting vibrations at its natural frequency. An oscillating data pattern can be the result of ringing. Ringing can be suppressed in a limited fashion by passive means. Alternatively, a control system can use an actuator to actively damp out the ringing of a load cell. This method offers better performance at a cost of significant increase in complexity.

***Dynamic load cell is ideal for measuring force transients or dynamic force pulsations in impact or vibration applications. This load cell contains a thin piezoelectric crystal that generates an analog voltage signal in response to an applied dynamic force.

Proposed frequency range which is quite common may be classified for the dynamic loads are given below.

Resonant Frequency (@ No Load): 75 kHz High Frequency Range: 25 kHz (approx. 1/3 of resonant frequency, no load) Low Frequency Range (-3 dB): 0.08 Hz
