Japanese torsion spring 180 degrees

The 180 degree torsion spring is a free state torsion Angle at the 180 degree position, the spring produces torque or rotational force. The ends of the torsional springs are secured to the other components, which pull them back to their starting position as they rotate around the center of the spring. Although the spring is called a torsional spring, it is subject to bending rather than torsional stresses. Torsional springs can store and release angular energy or hold a device statically by rotating a moment arm around the central axis of the spring body. This type of spring is usually tightly wound, but the pitch between the springs reduces friction. They create resistance to rotational or rotating forces. Depending on the application, torsion springs can be designed to turn clockwise or counterclockwise to determine the turn direction of the spring.

Calibration of customized butterfly spring induction contact data signal equipment barometer

1 A part of the household appliances of the pneumatic gauge and the grounding resistance in the middle of the housing should not be less than 20MQ (working standard voltage 500V) when the working temperature is 5~35℃ and the air humidity is not more than 85%.

2 Install the barometer on the school detector, and use the needle dipper to move the two data signals to touch the dial hands respectively beyond the limit and low limit, and then carry out the range measurement verification. After reaching the standard of range measurement verification, carry out data signal deviation measurement verification. The way is: the limit and the low limit of data signal touch hand are respectively set on three different metering detection points, metering detection points should be selected in the middle of the detection range of 20%~80%. Slow pressure change or blood pressure drop until the moment of the signal. The deviation between the gauge reading value and the data signal needle range shall not exceed 1.5 times the square root of the larger allowable base deviation.

Customized torsion spring measurement verification results and measurement verification cycle time

The barometer that has passed the metrological verification shall be incanted or sent to the certificate of conformity. If necessary, the charm seal is also sent to the certificate of conformity.

If the barometer fails to pass the metrological verification, it is allowed to be used in retrograde application, but the grade mark must be changed.

The cycle time of calibration of barometer can be defined according to the detailed situation, generally not more than half a year.
