PLC Application is a compact teaching and practice unit for the control of a materials handling process using a PLC. Two processes can be simulated: a punching process, or workpiece control in the form of a sort operation. The working cylinder can switch between sorting and punching modes by a simple sequence of actions. All components are in a clearly laid out design. Black and white cylindrical workpieces are fed from a container onto a conveyor belt. On the belt is a reflex photoelectric proximity switch which differentiates between light and dark and feeds the white items to the pre-selected process (punching or sorting). The unit is designed for operation in conjunction with a PLC module. Use of PLC module is recommended. The well-structured instructional material sets out the fundamentals and provides a step-by-step guide through the experiments.

Vickers Hardness Tester is fully automatic using a motorised system. The accurate load is applied on a diamond penetrator by means of a lever and weights. After a specific lapse of time the load is removed automatically. Vickers Hardness Tester is designed specifically for Vickers hardness testing. The testing range is very wide, from soft metal such as lead, upto the hardest, like hardened steel.
The sample specimen is then compared with the test piece and the diamond indentation is projected on the measuring screen. The diagonals of the indentation can be measured by means of the micrometer screw of the projection screen. The robust machine frame is designed to accommodate the high precision loading system and an optical projection screen specimen is placed on a testing table.
Experimental Capabilities:

A glass sided tilting flume with fabricated all stainless steel bed. Completely self-contained and comprising the working section, moulded inlet and discharge tanks, a series of sump tanks, a pump, an electronic flow meter, a jacking system and a control console. The channel section is fully glazed with large clear panels of toughened glass. A working cross-section of 300mm wide by 450mm deep and available in standard working lengths of 5m, 7.5m, 10m, & 15m. Longer lengths are available to special order in increments of 2.5m. The glass panels are sealed using a rubber section compressed by an aluminum alloy clamping strip. The flume bed is manufactured to high tolerances and designed with an integral web support frame to give the flume a high degree of rigidity and stability. This is coupled with careful design of the side support profiles to provide excellent visibility and allow flow visualization of the full working height of the flume. No under frame or support structure other than jacks is necessary. Rigid dowelled joints are used to connect the sections. The overall strength and rigidity of the design allows excellent stability figures to be achieved and eliminates the need to provide adjusting screws or to perform periodic setting up of the flume to maintain its specification.

The Trainer On Industrial Refrigerators With One Evaporator And A Semi-Hermetic Compressor With Fault Simulation allows to study the circuit layout adopted in the normal industrial refrigerators, fitted with positive temperature evaporator and semi-hermetic compressor. A wheeled frame carries a horizontal working panel, fitted with a 80 mm vice, and a vertical frame, where the main components of the unit and a silk-screen printed synoptic panel are mounted at sight. The refrigerant is Freon R134a (HFC), CFC free, and the unit includes the measuring instruments that are necessary to survey operating parameters and to test the refrigerator circuit. The student can rise his knowledge about the main components of a refrigerator plant, experiment the problems due to the filling and the emptying of the circuit and, at last, simulate some simple faults. The refrigerator circuit is made of copper pipes. The set of equipment and the vacuum and recharge station allow a fast assembly and disassembly of the refrigerator circuit.

The Compressors Test Bench is extremely versatile: in fact, it has been designed to allow to choose and mount compressors of different size and type, coupled to different electric motors, selected by the user. The Compressors Test Bench allows to experimentally characterize a wide range of air compressors, in a work field from 0 to 500 Nm3/h as regards the flow rate and from 0 to 10 bar as regards the pressure. The frame of Compressors Test Bench is very strong and has to be fixed to the floor; the bench is completely made of corrosion-proof materials. The high precision of the sensors installed in the Test Bench allows to perform accurate and trustable research experiments within the whole work field. An user manual is supplied with the equipment. The electric control and command board allows to operate in manual mode, by personal computer or by external board.

Rockwell And Brinel Combined Hardness Tester is bench mounted unit. The principle of operation is based around a lever and weights. The weights are applied to the free end of a lever, which then transmits pressure onto the plunger, which then indents the specimen under test. Rockwell And Brinel Combined Hardness Tester is designed for measuring hardness of metals and alloys of all types (hard and soft). The specimens can be flat, or round and irregular in shape. The weights are automatically selected. A range of indenters are also supplied with 1.58 ball, 2.5mm ball and 5mm ball. Two test tables are supplied in 50mm and 38mm, with the 38mm table incorporating a Vâ„¢ groove for holding round jobs from 6 .45mm. A dial gauge monitors the loading, while a rubber bellows protects the elevating screw from dust and dirt ingress. 15 Rockwell And Brinel Combined Hardness Tester scales are available to choose from.

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.
Large steam sterilizers are used for bulk sterilization processing and are typically found in the hospital's central supply department. Most operating suites and labour and delivery areas are equipped with smaller units for their own routine needs; however, areas that perform a great deal of sterilization may require large sterilizers.
Large steam sterilizer (autoclave) designed as tabletop model with a capacity of 80 litre featuring a front-loading door, suitable for bulk sterilization of wrapped, unwrapped, solid and hollow items as well as porous loads such as drapes and gowns. Electrically powered, requires a single-phase power grid supplying 230 volt, 50/60Hz, 7.4 kW.
Steam sterilization kills microbes effectively and is often viewed as the gold standard of healthcare sterilization methods. Typical items to be sterilized include surgical instrument packs, surgical implants, irrigation fluids, devices intended for and used by patients in isolation, and obstetric and dental instruments. Steam sterilizers use pressurized steam to generate moist heat to eliminate viable microbes from non-heat-sensitive medical devices, including heat-tolerant products used for surgical and general patient care.
