Foxboro 122-FE

Foxboro 122-FE Product Overview

Dear friends,when we talk about”industrial data recording”,modern equipment may be LCD screens and electronic memory cards,but in many industrial sites with a long history and extremely high reliability requirements,such as our refineries,chemical plants,and power plants,these”old and strong”Foxboro 122-FE pneumatic chart recorders are still”keeping their posts”!

This Foxboro 122-FE is not a”fancy”thing,it is a real mechanical chart recorder.Its core working principle is to receive standard 3-15 psig(pounds per square inch gauge pressure)pneumatic signals from field transmitters(such as pneumatic pressure transmitters and pneumatic flow transmitters).Changes in these pneumatic signals will drive the precision bellows inside the recorder to expand and contract,and the bellows will then drive the pen tip through a set of ingenious mechanical linkage mechanisms to draw real-time changing curves on special circular or long strip chart paper.

Don’t underestimate the process of”drawing lines”,it’s an”art”!The recorder can usually be equipped with one or two pens,each pen corresponds to an independent input signal,and is distinguished by different color ink.The chart paper is driven by a precision electric drive motor(usually 120V AC power supply),rotating or feeding the paper at a constant speed,thus forming a complete process curve with a time axis.

The advantage of Foxboro 122-FE lies in its simplicity and reliability.Because it is purely mechanical and electrically driven,it has strong adaptability to the environment and is not as delicate as digital devices.It can still work stably under many extreme working conditions.Moreover,the data it records are real paper charts,which are intuitive and easy to understand.They can be viewed without computer software,making it convenient for on-site personnel to quickly judge process trends and anomalies.In situations where historical data needs to be stored for a long time and there are requirements for data authenticity and tamper-proofing,paper records are often more convincing than electronic records.It does not require complex programming and network configuration like modern digital systems,and installation and debugging are relatively straightforward,which is very suitable for on-site applications with low technical requirements.
