The Bedia capacitive level sensors are suitable for industrial applications, are practically maintenance free and have a wide operating temperature range.
The Sentry Gas Concentration sampling system allows the operator to extract a representative sample of hazardous or toxic chemicals and use handheld devices to test concentrations (such as Dr ger and Rae gas detection tubes), while protecting the operator and environment from contact with the dangerous vapours.
The Sensortechnics CLC series capacitive level sensors use a contact-free capacitive sensor technology to continuously measure the fill level of liquids as well as granular or pulverised materials.
The Sensortechnics LBA series pressure sensors can be used for ultra-low differential pressure measurement and are suitable for medical equipment, HVAC and measurement and control applications.
Alicat Scientific’s ATEX-approved mass flow meters and mass flow controllers are approved for hazardous environment (-X) option and are designed to be used in environments where ignitable gases are present.
The Sentry Model MVD manual speed loop sampler needle/tube stub liquid sampling valve can be used to collect process samples without emissions to the atmosphere or exposure to the operator. It provides double block valve safety without dead volume.
The technology in Alicat Scientific laminar mass flow meters and mass flow controllers compensates for changes in process temperature and pressure - providing fast (\<10 ms), stable and accurate readings.
The Deltaflux orifice flowmeter can be used for measuring gas and liquid flows and is suitable for high flow-rate measurement and control in process flows, water treatment and gas furnace applications.
The Alicat Scientific electronic digital pressure/flow controllers are claimed to be more precise than standard valve-type pressure controllers and have a variety of output options including 0-5 V, 0-10 V and 4-20 mA and RS232.
The Duff & Macintosh centrifugal pump test set is a self-contained, robust, good-quality apparatus that allows a comprehensive range of tests and investigations in laboratory demonstrations, student experiments and project work.
TecQuipment’s Technology and Science Kits (TASK) range, can be used to teach the principles of mechanical engineering. It offers a flexible and safe method to develop hands-on experiments, suitable for many academic levels, from teaching fundamental principles in schools to demonstrations at undergraduate level.
The TecQuipment benchtop heat exchanger is a bench-top service module with optional small-scale demonstration heat exchangers - designed for engineering teaching in tertiary laboratories.
The TecQuipment modular Structures range is a flexible teaching system designed for engineering teaching in tertiary laboratories.
The TecQuipment modular Structures teaching system range, available from Edutechnics/Duff and Macintosh, can be used for engineering teaching in tertiary laboratories.
The Sentry Equipment LNG sample panel (model MCG) is claimed to simplify sampling of single- and two-phase fluids. Using the tandem valve, the operator can take a sample quickly and easily by operating just one single levered valve instead of many.
The Alicat Scientific M series mass flow meters and mass flow controllers can be used in a variety of measurement and control-based processes.
TecQuipment designs, develops and manufactures a comprehensive range of products for engineering education.
The Alicat mass meter M series monitors the carrier gas and capillary flow rates of a gas chromatograph (GC) for multiple gases and pressures. With an optional battery pack, the device becomes a portable flow measurement device to check and maintain these parameters on a range of machines.
Sentry’s sample cylinder allows gas samples to be collected at pressure, assuring that the sample constituents that can change state with pressure reduction are not lost during sample collection. An example of this type of sample would be LPG or other two-phase fluids that could flash off sample constituents if the pressure was reduced.
Alicat Scientific has launched a line of low flow (0.5 to 50 SCCM) mass flow controllers.
Duff and MacIntosh has introduced a number of flowmeter products to Australia, with many brand names of flowmeters over the years.
