TE37
Control and Instrumentation Study Station
Description
Learning Outcomes
The Control and Instrumentation Study Station uses
industry-standard parts to teach industrial process control.
It is an excellent tool to help train plant technicians and
process control engineers.
• Setting up process transmitters
Hot and cold water supplies connect to the study station.
Two valves (worked by compressed air) control the flow
of the water supplies into a process vessel. The process
vessel has three jobs:
• Coupled and decoupled interactive control
• A pressure vessel with a pressure-relief valve for safety
• Feedforward-feedback control
• A temperature-mixing chamber for the hot and cold
water flows
• Split range control
• Level, pressure, flow and temperature control
• Cascade control
• Ratio control
• Feedforward control
• Fault-finding
• A liquid-level reservoir with a sight gauge
Transmitters on the pipework and process vessel send
flow, level temperature and pressure signals to a patch
panel. Other sockets on the patch panel connect to the
valves and other instruments. The students use leads
(included) with the patch panel to connect the instruments
and valves for any particular experiment.
The two flow transmitters are differential pressure
transmitters, connected across orifice meters. The hot flow
transmitter normally connects to an orifice meter in the hot
water inlet. A set of hand-operated two-way valves also
allow it to connect to a third orifice meter in the drain pipe
from the process vessel.
Essential Anc illary
• Service Module (SM37) – This module connects to a
suitable cold-water supply and outputs hot and cold
water at the correct flow and pressure for the Study
Station. It includes an air compressor and storage
vessel to supply compressed air to the Study Station
valves.
R ec o mmend ed Anc illary
• Distributed Control System (TE37DCS) – Refer to
separate datasheet
The study station includes two fully configurable
controllers, each with remote or local set point inputs. The
controllers are industry-standard, with a choice of different
control methods, and fully adjustable proportional,
integral and derivative (PID) circuits. Sockets on the patch
panel connect to an electronic multi-channel recorder to
log changes in process variables.
Note: The chart recorder is paperless, so you need a
suitable computer and colour printer if you need to print
out hard copies of the chart recorder traces.
For fault-finding practice, there is a set of hidden switches
on the side of the study station. These switches break the
electrical circuits from the transmitters, instruments and
control valves.
