Temperature/Flow Process (3522)
 
產品簡介
  The Temperature/Flow Process is a portable, bench-top unit designed to familiarize students with the fundamentals of instrumentation and process control. Advanced concepts such as cascade and feed-forward controls can also be studied. The trainer provides a temperature process and a flow process. Process control is achieved through an external controller which is compatible with either standard 4-20 mA signals or 0-5 V signals.
