Understanding The Working OfA Strip Chart
Recorder
2
Overview

• Strip Chart Recorders make use of long strip or
  roll of paper to archive data points over a time
  period. 
• One or more sensors acquire data. Strip chart
  makes use of one or more pens to plot data
  linearly as chart passes through uniform speed.
• Benefits of strip chart recorders are real-time
  output, ease of operation and hardcopy produced
  by the device.

• What Is A Strip Chart Recorder?
• The strip chart recorders are roll or strip of
  paper that archives data points over an interval.
  By using data acquired by one or more than
  sensors, strip chart recorders use one or more
  pen to plot the data linearly as the chart passes
  at a uniform speed. Strip chart recorders
  advantages in the process of operation with ease
  and by providing real time output.

Strip Chart Recorder Technology

• Strip chart recorders give you data.
• Data is produced by using special sensors
  attached to the recorder. Sensor types include
  current, strain gauge or bridge, humidity,
  pressure, level, pH, pressure and temperature,
  among others.
