Heat to expand the captive gas charge and drive the power piston is provided by an electrical element controlled from the standard instrumentation console.
A bench top accessory designed to allow students to experimentally investigate one of the methods available to convert heat energy directly into work.
The cycle of the engine consists of two isothermal processes and two constant volume processes.
Wound Rotor Motor Learning System covers the function, operation, and performance characteristics of wound rotor motors. The Wound Rotor Motor Learning System requires the Basic Electric Machines Learning System and the DC Generators Learning System for use. While VFDs and standard induction motors have replaced wound rotor motors in many applications, these motors are still used for heavy-duty, high torque applications such as industrial cranes and hoists.
The Wound Rotor Motor Learning System includes a wound rotor speed controller, a wound rotor motor, banana leads, in-depth curriculum, an installation guide, and a student reference guide. Learning systems feature real-world, industrial-grade components for both durability and to facilitate learners in gaining hands-on practice with actual equipment that they'll find in the field. These components will be used to study topics such as wound rotor speed control, performance characteristics, and motor reversing.

The materials used in the manufacturing of the HeavyDuty Planner Machines ensure high durability, tensile strength and resistivityto adverse conditions. Planner Machines due to the unmatched quality andunsurpassable performance. Moreover, easy operation, less input requirements, highoutput and low maintenance cost are some of the factors that distinguish ourPlanner Machines from others available in the market.
Features:
The Table: It is of box section type and is streamlinedwith hand scraped V way to bear heavy load. It is heavily ribbed and the Rackprovided in it is accurately machines and milling cut.
The Bed: The bed of planner machine is of deep boxsection type and is tied together atfrequent intervals by double walled bridgepieces extending to the bottom of the bed.
The Cross Rail: This is of Box section type with largesurface. It is suitable for both hand and mechanical drive.
The Drive: The planner machine is arranged for directindividual as well as two belt drive.
Tool Posts : These are manufactured out of close grainalloy castings and steel to stand heavy cut. These can be driven both manuallyand mechanically.
The Uprights: The uprights of planner machine are ofrigid box section type. Keyed firmly, bolted on to bed and are capable ofabsorbing the heaviest shocks without vibration. Extra pins are provided tore-fit the machine accurately after once it is dismantled.
The Bearings: The main bearings for the Gearings arecast solid with the Bed. The Gears Teeth are hobbing machine cut except toogears are helical. Gun metal bearings have been provided for all the shaft andloose pulleys. Taper roller bearings can also be provided instead of Gun metalbushes.
Accessories: Automatic liftingarrangements of cross rail.
The lower value (diastole) corresponds to the pressure that we have in the arteries between two heart beats. The upper value (systole) is the maximum pressure that is recorded in the artery in consequence of the heartbeat. In blood vessels there must be a certain pressure in order that the blood can properly flow. Each heartbeat causes a pressure wave that is transferred to the arteries. Therefore, it is necessary to properly evaluate the pressure and its variability through a pressure and heart beat digital meter.

This tabletop learning system showcases a full range of components, such as a fire syringe, a vacuum hand pump, bi-metallic ball and ring, and many more on a vertical panel for easy access and inventory. Thermal Science Learning System provides learners with the knowledge and equipment needed to comprehend the principles of modern thermal systems, such as HVAC, geothermal, refrigeration, and steam systems. These components are used in various combinations to conduct experiments that show learners physical examples of thermal concepts and build foundational knowledge that they can use in real-world applications. As learners progress through the curriculum, they will perform experiments demonstrating principles such as the ideal gas law, linear and volumetric thermal expansion, basic temperature measurement, latent and sensible heat, specific heat capacity, conduction, convention, radiation, evaporative cooling, and basic refrigeration.

The movement is obtained through pneumatic cylinders, commanded by On-Off solenoid valves, allowing to reach 8 positions to lift and to lower the gripper and to open and close the grip. Pneumatic robots are widely utilised in the industry for the movement of parts with limited dimensions and weight at high working rate. The use of industrial components operating with lubricated air assures high accuracy.
