The automatic code-adding system fully automatically completes the weight-reduction weights and weights of the weights. The weight distribution and its characteristics are as follows:
1. When the pressure p<32MPa, the tubular weight is used:
The nominal pressure is 0.5MPa, 1MPa, 2MPa, 4MPa, 8MPa, 16MPa, each weight, the weight of the weight is more scientific, and the weight is parallel. The weighting method is less than the serial weight, and the code response speed is fast. The average acceleration speed is about 2 seconds.
2. When the pressure is 32MPa ≤ p ≤ 120 MPa, the combination of the cylindrical weight and the plated weight is adopted:
32 MPa weight 3 groups (to facilitate the delivery of the piston system 32MPa weight code is a combination of two).
And because the code-adding system adopts the advanced binary code-adding method to greatly reduce the number of weights under the premise of loading any integer pressure point within 1~120MPa, the total number of weights is 9 groups, the number of 12 blocks is far less than the number of serial weights. (33 blocks), the effective control of the number of weights is more conducive to the inspection of the weight piston system, greatly shortening the time of the code and the frequency of the code, effectively reducing the wear of the weight, improving the accuracy of the weight, and the detection data is more stable and reliable. Precision.
The mirror-level weight is resistant to friction, dust and ash, easy to clean, and can maintain accurate and constant weight for a long time. With weight rotation monitoring system, real-time report weight operation status, according to user needs, can process kilogram group or MPa group and modify the pressure deformation coefficient and local gravity acceleration.
Weight material: non-magnetic stainless steel (0.005 grade; 0.01 grade; 0.02 grade; 0.05 grade)
The servo system controls the pressure source to automatically pressurize and measure and control through the high-precision automatic piston pressure gauge sensing transmission device. The automatic constant system pressure is provided, which is especially suitable for automatic detection of precision and ordinary pressure gauges.
The automatic code-adding system uniquely creates the piston cylinder up and down limit function at the same time, so that the pressure change of the checkback of the checked precision pressure gauge, pressure transmitter, sensor, etc. is continuously decreased, and the return error of the checked watch can be strictly checked.
Piston anti-break bar (domestic initiative) structure. The structure solves the problem that the piston rod is broken due to improper method of the user during the operation, for example, the weight of the bump, the drop, etc., make the user feel more comfortable.
Pressure output: M20×1.5 standard quick connector
The automatic pressure system has an oil level detection function to prevent detection failure due to lack of pressure oil; the oil cup has a quick oil discharge function, and the contaminated pressure oil can be periodically replaced.
The detection port has a sewage discharge function, which can regularly exclude the dirt brought in by the pressure gauge.
