Description
Technical Details

Maintenance and calibration training system (MMS115) aims at providing the required knowledge about the definition of “control loop”. Control loop consists of all physical components and control functions needed to adjust or maintain the value of a measured process variable (PV) to a desired value, or setpoint (SP) including: primary element/sensor, transducer & transmitter, signals, controller & actuator. The system focuses on the transmission process of both pneumatic and electrical signals generated in transducers (electrical) and control valves (pneumatic) control loop elements in addition to the calibration & testing of different corresponding electrical and pneumatic components.

System can demonstrate the transmission behavior of electrical and pneumatic signals in the control loop components including transducers and control valves.
The system is provided with different sensors, transducer /transmitter, controllers & actuators to constitute a complete control loop.
Since there are two types of signals in industrial automation, the training system is provided with components to generate and test both types.
System is provided with two pressure regulators with manometers to create pneumatic signals and calibrate manometers at high pressure.
The pneumatic output signals from control loop components can be measured using two precision manometers.
Low pressures are generated for manometer calibration using a height-adjustable tank with scale.
Electrical and pneumatic signals can be generated to effect actuation of the individual control loop components.
The trainer is provided with a precision measuring technique that permits recording the output signals from the control loop components.
The pressure regulators can also be used to calibrate at higher pressures.
Auxiliary power sources for components that require an electrical supply are provided at the form of DC voltage sources.
Direct current signals can be sent and measured with two controllers.
Two precision manometers are used to measure of pneumatic output signals from control loop components.
