New particle strength tester

KY-20Digital particle strength testerIt is a dual row digital instrument that uses sensing measurement technology to achieve instantaneous value display and peak locking. This instrument has the advantages of small size, direct reading of measurement values, high accuracy, and easy use. It is an ideal new experimental instrument for determining the strength of particle samples such as catalysts, fertilizers, and drugs.

Instrument precautions:

vWhen not powered on, do not rotate the handwheel clockwise casually to apply force to the force rod in contact with the sample plate, in order to avoid damaging the sensor due to overload.

vAt the end of the experiment, attention should also be paid to keeping the force rod away from the sample tray, confirming that it is in a non stressed state, and turning off the power.

vWhen the force is greater than the maximum range,The handwheel should be rotated counterclockwise in a timely manner,Separate the force rod from the sample and end the experiment.

vDuring the experiment, when rotating the handwheel clockwise, it is not allowed to suddenly rotate it counterclockwise to reduce the force, otherwise the instrument will misjudge that the sample has been broken and lock the invalid value.

vDuring the experiment, when the particles have been subjected to force, the force should be slowly and evenly applied to continue increasing, so that the rate of force rise is as low as possible until the test sample particles are crushed, which can ensure measurement accuracy. For example, the actual strength of particles in a certain sample is50N,And the rate of force increase is relatively high,Assuming10N/second,Due to this instrumentA/DThe sampling frequency is approximately5time/second,The instrument may measure as48N左右,If reduced to1N/second,The measured value corresponds to49.8N左右。

vThe experimental force is1NThe following is the non sensitive range for peak locking of this instrument. At this time, the maximum value that occurs when the sample ruptures can be used as the intensity value.
