A chart recorder is an instrument used to record signals like voltage and temperature. They produce the data on a paper chart allowing you to look at historical trends.
Chart recorders come in different shapes and sizes. They are so diverse that choosing the right one for your work can be confusing. Before buying one, here’s everything you need to know about chart recorders to make an informed decision.
The Chart Recorder’s Designated Purpose
Evaluate the chart recorder’s purpose first. Ask yourself the type of data you intend to measure. Is it temperature, humidity, or diagnostics for engineering projects? This factor will impact which of the various types of analog chart recorders you decide to choose.
The Chart Recorder’s Speed
Chart speed refers to the rate at which the paper moves through the recorder, ultimately determining the time resolution of your recorded data. Finding the right balance between speed and detail is important.
Selecting a faster chart speed will provide more intricate and granular data. However, it’s worth noting that faster speeds will cause decreased recording times.
The Chart Recorder’s Number of Inputs
The versatile device offers a range of options when it comes to the number of inputs or channels. They can come with a single input for measuring a single parameter or multiple inputs for measuring multiple parameters simultaneously.
Choose a device with multiple inputs when you need to monitor multiple parameters simultaneously. Doing so provides comprehensive data for a holistic understanding of the system. However, keep in mind that recorders with more inputs are typically more expensive.
Alternatively, a single-input recorder is sufficient and cost-effective for a single parameter. This type of recorder allows you to focus resources on capturing accurate data for the specific parameter of interest without incurring unnecessary expenses.
The Chart Recorder’s Data Analysis Capability
Data analysis is another essential component of chart recorders. These features include statistical functions, real-time calculations, and customizable alarms. Using these advanced features saves time when analyzing complex data patterns.
Consider your specific data analysis needs. Factors to contemplate include handling various data types, data storage capacity, and data visualization options. Detailed analysis uncovers valuable insights and trends. Leveraging a chart recorder unlocks the full potential of data, revealing patterns and relationships.
Professional industries are lost without an analog chart recorder; there wouldn’t be sufficient and accurate data to guide each project. Outlining everything you need to know before buying a chart recorder will make your decision especially simple, so your business can benefit.
