Set of 5 different sizes cuffs to be used with an existing blood pressure meter.
INTENDED USE
It is wrapped around the upper arm or the leg (thigh) of the patient. This is a reusable device which may be intended for single-patient or multi-patient reuse. A band-like device that has an inflatable bladder in an inelastic sleeve with one or two connecting tubes with connector (typically locking connectors) that can be connected to a mechanism for inflating and deflating the bladder and/or a sphygmomanometer or a patient monitoring device/system that is used to determine a patient's blood pressure.
The pressure transducer is directly exposed to the combustion chamber pressure when the spark plug is inserted. The spark plug itself retains its full functionality. For experiments using cylinder pressure indication on the test engine, the normal spark plug is exchanged for a modified spark plug. This modified spark plug is fitted with a micro pressure transducer. The pressure transducer is connected to the measuring amplifier in the electronic indication system. The core component of the pressure transducer is a heat resistant piezo-electric quartz crystal, which outputs a charge signal proportional to the pressure.
Learning Objectives/Experiments:
Cylinder pressure measurements on internal combustion engines.
For CHILD or ADULT wheelchair users who are at risk of pressure injuries and who need good support to maintain stability and an aligned posture. Cushion and cover function to reduce heat and moisture generated when the user is sitting on the cushion.
Pressure-redistribution cushion with moderate/partial offloading or immersion/envelopment features: Contoured cushion with separate top layer.
For CHILD or ADULT wheelchair users who are at risk of pressure injuries and who need good support to maintain stability and an aligned posture. Cushion and cover function to reduce heat and moisture generated when the user is sitting on the cushion.
Pressure-redistribution cushion with moderate/partial offloading or immersion/envelopment features: Contoured cushion without top layer.
The automatic data acquisition and analysis system for Personal Computer allows to take the measurements automatically, plot on screen or print out and file the test data. The Pressure Transducers Study Module allows to study the calibration methods for a signal conditioner instrument connected to a pressure transducer and to verify the system linearity, repeatability and hysteresis.

Pressure Control And Regulation Study Unit makes it possible to analyse the behavior of a control loop where the controlled quantity is the pressure of the air ina tank. Pressure control is one of the main problems encountered in factory automation and process control. Students can examine the effects of the different control parameters on the performance of the control chain and on the stability of the system; furthermore, they can become familiar with the components commonly adopted in modern industrial applications, as the system is entirely made of industrial quality components. With this trainer, all the tests can be performed through a Personal Computer and a special software for Windows. This makes the problem of choosing the most suitable control technique very interesting. Compared to other quantities such as the level or the temperature the pressure varies as a function of the regulating signal in a very quick way.

Hydraulic feed is obtained through an adjustable height reservoir at constant hydraulic head. Pressure losses are measured by means of two U manometers, one water type (800 mm) and the other mercury type (400mm). The Apparatus For The Determination Of Pressure Losses In Pipes has been designed to determine the pressure loss in a pipe in which water is made to flow.
Experiments:
Measurement of pressure loss in a pipe as a function of flow-rate.
Change from lamnar to turbulent flow.
Verification of Reynolds number.

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.

The pressure profile is indicated by the different heights reached by the lubricant in the tubes. The unit is intended for use with the basic module 13 measuring points that open out into measuring tubes are distributed around the periphery of the bearing shell. The unit enables the pressure distribution in a plain bearing with hydrodynamic lubrication to be displayed. Due to the radially adjustable bearing housing, the width of the gap can be adjusted in 1/100mm steps using a micrometer.

The Pressure Homogeniser has been designed to complement the other processing equipment in the miniature-scale R & D range. The unit can also be used for salad creams and sauces. The double action of the homogeniser valve causes the mixture under pressure to be subjected to shear and compressive forces between the valve faces and impinge violently against the walls of the chamber, ensuring thorough dispersion. This index refers to testing homogenised product for fat content at the top and bottom of a sample and comparing the difference. Normal standards require an index of less than 12%. It is particularly useful for disintegrating fat globules in milk, ice cream and UHT dairy products. Results of performance using whole milk gave homogenisation indexes of 5%.
Features:
Hardened stainless steel cylinder block, valve and piston
Positive displacement piston
Specially developed, double action Stellite homogenising valve, eliminates the need for multiple valve heads
Rapid throughput, 45 litres per hour
Integral electric motor drive
Homogeniser index less than 5%.
