Applicable to manual or mechanical low and medium pressure molding of fine, coarse sand (core) surface hardness test.
According to the principle that the force of the spring is linear with the stroke, the distance of the stroke is expressed by the surface pointer through the transmission of a set of gears and racks.
Model:SYS-B
Compression stroke:2.50mm
Maximum load:980G
model number: SYS-B
Part Number: SYS-B
Details: Usage method
Adjust the 0 bit, when the pointer is not in the 0 bit, turn the adjustment ring, so that the pointer to 0.
When used, the hardness is pressed in the sand on the test plane (axis hardness of the surface to be perpendicular to the plane of the sand), sand hardness meter gauge plane and the close contact, the pointer is stopped at a certain value, press the locking pin to lock, reading test a fixed value, and then releasing the locking pin so that the pointer reply 0.
The determination was made at 3~5 times per assay, and then the average number was calculated, as well as the hardness of the part.
Technical parameter:
Model:B type
Compression stroke:2.50mm
Maximum load:980G
Load under pressure:50g
Head shape and size:Ball R12.70
Accuracy:
When the pointer is at any value, the relative force of the pressure head is equal to + 5%
When the pointer goes back to the 0 bit, the tolerance is 1 degrees
Outline size:90 x 55 x 28mm
