Chart recorders are actually instruments that are used for the recording of different types of processes as well as electrical signals. The most traditional form of chart recorders is the ones that record data on paper. The paper usually passes under the pen where the pen simply deflects in proportion to the signal that is sent. The result so obtained on the paper is a graphical form of data or a chat that represents the data. Now, with the passage of time and the evolution of technology different types of chart recorders have come into existence giving improved as well as accurate results.
Types of Chart Recorders
There are a number of different types of chart recorders available and are required to be chosen as per the specific needs or requirements. The different types of chart recorders areas listed below.
- Strip Chart Recorders
- Circular Chart Recorders
- XY Chart Recorders
- Paperless Chart Recorders
- Hybrid Chart Recorders
What are Circular Chart Recorders?
As indicated by the name, these chart recorders record data in a circular format. Here the paper is allowed to spin under one or more pens. The pen or pens are then deflected in proportion as per the varying signals received and the result is a circular chart. The circular charts are designed in such a way that they normally rotate in the standard time periods like one hour, twenty-four hours, seven days, etc. But many of the circular chart recorders are quite flexible for the accommodation of time periods that are non-standard as well. This is the reason why recorders are considered to be extremely versatile in nature due to their adaptability to time periods.
Types of Circular Chart Recorders
The circular chart recorders are usually of two types which are as follows.
- Single pen circular chart recorders
- Dual pen circular chart recorders
Functions of Circular Chart Recorders
The circular chart recorders are perfectly suited for the batch processes where the time for the set processes is known. This becomes easier since the circular chart recorders are specifically designed to rotate for fixed time periods and hence can be adjusted accordingly. This makes the recorders ideally suited for the intended purpose of use which functions just appropriately.
Applications of Circular Chart Recorders
The circular chart recorders find a wide range of applications in cases where there are batch processes. Some of the general applications of the circular chart recorders are as mentioned below.
- Monitoring of the level of water at the time of water treatment or in a treatment plant
- Measuring of temperature as well as humidity in drying of wood or any other similar types of drying processes
- Monitoring of pressure in the room in cleanroom applications
Apart from the applications mentioned above, there are a lot of applications of the circular chart recorders. But at this point in time, it is to be made sure to buy the circular chart recorders from a trusted and reputed circular chart manufacturer for the purpose of getting top-quality products.
