Paper recording charts and consumables consist of circular charts, strip charts, markers, fanfolds, sheets, pens, and pen arms used in chart and strip recording instruments. A chart recorder is an instrument used to record various process and electrical signals. The paper is passed under a pen and the pen is deflected in proportion to the signal. The result is a graph or chart of the data. There are many types of paper recording charts. Examples include circular charts and strip charts. Circular charts are used in circular chart recorders which record data in a circular format. The paper is spun beneath one or more pens. The pens are deflected in proportion to the varying signal resulting in a circular chart. Strip charts are used in strip chart recorders which consist of a roll or strip of paper that is passed linearly beneath one or more pens. As the signal changes the pens deflect, producing the resultant chart. Paper recording consumables refers to various other instruments and materials, such as sheets, paper, and pens, which are used in a chart recorder. Other paper recording charts and consumables are commonly available.
Paper recording charts and consumables are available in various sizes according to the required specifications. Chart recording paper is defined by its part number, which determines its size. Various sheets of paper are used for making a particular type of chart. A specialty paper called strip chart paper is used for making strip charts, which are used with strip recorders. An industrial recording chart is used with an industrial recorder. Generally, industrial recorders have the recording width of 100mm and 180mm. Recorder pens are an important paper recording consumable used in chart recorders. Recorder pens are used to write in style and record the data. Recorder pens may have fiber tip or micro tip. Paper recording charts and consumables are manufactured to meet most industry specifications.
Paper recording charts and consumables are used in many applications. Examples include its use in recording data of a given environment, such as refrigeration, air conditioning, storage, transport, and workplace or home monitoring. Paper recording charts and consumables should adhere to various standards specified by American National Standards Institute (ANSI) and International Standards Organization (ISO) standards.
