Multifunction Process Control Teaching System

• A multi-function process control teaching system, capable of demonstrating level, flow, pressure and temperature control loopsDesk-top mounted and includes a
• Desk-top mounted and includes a built in USB computer interface
• Options include: reactor vessel with conductivity measurement, pH measurement, pneumatic control valve and electronic console

Includes the following process control demonstrations:

Process principles • Calibration of sensors (via PC software) • Inflow control • Outflow control • Direct heating • Indirect heating • Batch and continuous operation • Effect of sensor lag (e.g. thermometer pocket) • Effect of system time constant (e.g. volume change) • Effect of dead time (e.g. holding tube) • Effect of mixing/stirring

Measured variables • Level - on/off switch (fixed hysteresis) • Level - differential on/off switch (adjustable hysteresis) • Level - proportional pressure sensor (slow system response) • Flow - Proportional turbine sensor • Temperature - on/off switch (fixed hysteresis) • Temperature - proportional thermocouple sensors • Static pressure - proportional sensor (fast system response) • Differential pressure - proportional pressure (fast system response) • pH - proportional sensor.
