The slip forces between two rotating friction discs in contact can be determined using this accessory module. The slip between the discs is maintained at a constant 4% by a gearbox. The contact pressure can be adjusted in steps (10N) up to max. 80N.This adjustment is performed using a lever with a mechanical advantage of 2:1. The unit is intended for operation with the basic module. The unit has a container for supplying lubricant. Knurled bolts enable the friction discs to be changed easily. Connection to the basic module is made using a clamped coupling. A strain gauge force transducer connected to the controller measures the friction forces directly.

The Intermediate Pneumatics Learning System includes directional control valves, check valve, pneumatic cylinder, Venturi block, assorted filter elements, and much more. Commitment to using top-flight, industry-standard materials ensures that learners work with components theyll actually see on the job. Intermediate Pneumatics Learning System builds on basic pneumatic skills by introducing more advanced concepts such as air logic, ways to decelerate a pneumatic cylinder, and how to prevent condensation in a pneumatic circuit. Learners will have the opportunity to study these concepts while working with a hands-on training module, which enables practicing skills such as connecting and operating a two-way valve and changing an air filter element; this approach of simultaneously teaching theory and practice reinforces each element and results in a thorough understanding of the topic. The Intermediate Pneumatics Learning System covers topics such as motor loads, pneumatic cylinder loads, and quick exhaust valves, while the is the first product to offer a realistic troubleshooting experience for learners because the faults are inserted throughout the system. This attention to quality and detail culminates in a durable, attractive, user-friendly learning system that will last for years. After completing the curriculum, learners can continue to build on these skills by moving on to Advances Pneumatics Learning System and the Pneumatics Troubleshooting Learning System.

In this course students will study some circuits for analogue to pulse conversion, sound indicator and analogue frequency meter. This board does not substitute the medical device under study. The events monitoring systems such as the frequency of the cardiac pulsations, the breathing frequency, etc., require that an analogue signal be converted to pulses and visualized on a display in order to be measured. They are just for demonstration purposes. The results of the experiments have no medical value.
Circuit blocks of Pulse Conversion
Measurement of the frequency of a periodical signal.
Circuit for the conversion of an analogue signal to a pulse signal.
Evaluation of the average cardiac frequency.
The losses of the most important fittings can be determined using seven differential pressure sensors. Control response and energy flux can be plotted using four temperature sensors, a flow rate sensor and an effective power sensor. The trainer contains a complete closed heating circuit with circulating pump, electrical heater, and convector for dissipating heat, various pipe sections, fittings and safety devices. The characteristics of a conventional circulating pump and a differential pressure controlled circulating pump can be compared.

The unit is mounted on a structure of anodized aluminum profiles with painted steel plates , which has adjustable legs installed.
The unit basically consists of:Two porticoes:
A 50 cm. height portico, where the experimental strut will be subjected to load by means of a spring balance situated at the upper part and which will tend to elevate the lower beams, so the experimental strut will be subjected to compression.
A 1 m. height portico, where the test struts are placed. It is designed to accommodate struts of different height by using two pins. Therefore, at the upper and lower parts, there are special clamps to subject the strut to the desired ends conditions.
Balance 0-50 kg to measure the strut compression load, with 200 g accuracy.
Weight of 1 kg.
Bubble level to equilibrate the system.
Dial gauge, measurement range: 0-20 mm, precision: 0.01 mm, to check the strut flexion according to the experimental strut is subjected to load.
Regulation nut which, together with a bubble level, will allow to equilibrate the horizontal beams.
The apparatus consists of a turntable carrying two pairs of masses mounted on radius rods and linkage so that the centripetal force is measured using direct weighing by masses placed on the central carrier. Centripetal Force Apparatus permits accurate determinations of the relationship between force, mass radius and angular velocity of a rotating body. A similar pair of radius rods beneath the turntable compensate for any force due to the rods themselves. The masses, which may be separated to show the effect of equivalent mass, may be fixed at any radius from 75 mm to 250 mm along the graduated radius rods. One or more of the masses may be removed. For experimental work the mass, radius and angular velocity may be varied.
Features:
Precision electronic tachometer
Variable speed electric drive
Counter balanced operating linkage.
