Problems solved by technology

Occasions that require high temperature control accuracy cannot meet its requirements. For example, in the process of canned food sterilization and fresh-keeping in the food canning industry, the temperature is required to be controlled within the error range of 1 °C, and the import and export of this industry are in the Internationally, the FDA standard of the United States is usually followed, and it is necessary to attach valid records during the entire fresh-keeping process when importing and exporting
However, the accuracy and resolution of existing circular chart recorders cannot meet this requirement.

Embodiment Construction

[0012] Divide the display scale including its corresponding recording paper into a low-precision area and a high-precision area. The scale arc length of the high-precision area is larger than that of the low-precision area, and the high-precision area has a high-precision, high-resolution belt range. extended area. Corresponding to the above-mentioned indication scale, a point is welded on the sliding line resistance plate in the measuring unit as an inflection point, so that the sliding line resistance is also divided into two areas corresponding to the indication scale, which are divided into low-precision area and high-precision area. The low-precision area is from the beginning of the resistance to the inflection point, and the high-precision area is from the inflection point to the end of the sliding resistance. This point is to change the original sliding wire resistance, which leads to the problem of the tap of the sliding wire resistance. Because the measurement accura...

Abstract

This invention relates to a round recorder range extension method, which comprises the following steps: 1, dividing the relative recording paper of the scales into low and high accuracy areas, wherein the high accuracy scales arc longer than the low accuracy scales arc; 2, welding a point as inflexion on the resistance panel in the measurement unit relative to the above scales to divide the slide lines resistance into two areas of high and low accuracy areas, wherein the area from the sliding resistance initial end to inflexion is the low accuracy area and the other area is the high accuracy area.

Description

SUMMARY OF THE INVENTION [0001] The invention relates to a method for expanding the range of a circular graph recorder, belonging to the technical field of automatic instruments. Background technique [0002] The existing circular graph display recorder is generally a scale area, and its corresponding measurement loop is also a measurement area. For occasions with high requirements for temperature control accuracy, it cannot meet its requirements, such as canned sterilization and fresh-keeping in the food canning industry, the temperature is required to be controlled within the error range of 1 °C, and the import and export of this industry are in Internationally, the FDA standard of the United States is usually used, and it is necessary to attach valid records of the entire fresh-keeping process when importing and exporting. However, the accuracy and resolution of the existing circular chart recorders cannot meet this requirement. SUMMARY OF THE INVENTION [0003] In or...
