26 <strong>19.5</strong> Compact block valve series – the next generation The new and, at the same time, smallest of the five actuator The new and, at the same time, smallest of the five actuator sizes of the iComLine® is setting standards in the area of miniature valve designs. This valve size offers a flow capability of 2.0 litres per minute, whilst the height of the pneumatic actuator is scarcely larger than the diameter of a 2 euro coin. The small area of 20 x 20 mm is setting new standards in the area of ultra pure pneumatic valves. Developed primarily for customers from the chemical and semiconductor industries, the iComLine® product line can now cover a wide range of uses. With a focus on process equipment, in addition to providing a compact design and high resistance to media, the iComLine® series also makes it possible to use valves as a multifunctional unit in the form of a multi-port valve block. Various actuator and connection options, as well as a corresponding range of accessories, are also available. These options, coupled with the performance capability of the valves, open up numerous new areas of use. The new actuator size enables the valves to be used for applications in semiconductor production, laboratory and process analytics, as well as in the manufacturing of energy storage systems. The visual design and necessary operating parameters are identical to all other valves in the GEMÜ iComLine® series. claudio.darpin@gemue.co.za New multifunction measuring tool for all professionals in HVAC and industry The AMI 300 is a new multifunction instrument which is a key measuring tool for all professionals in HVAC and industry. The unit can measure up to 6 parameters simultaneously for pressure, temperature (RTD, thermocouple, NTC), humidity, air quality, air velocity and airflow, and tachometry. Some 12 000 values can be stored and then restored on PC through wireless communication. The AMI has a large 70 x 50 mm display (with bargraph) which allows quick reading of results and browsing is easy via a joystick on the keypad. The wireless probes are supplied with a multifunction key to allow measurement and settings. A large choice of probes are available such as vanes with diameters of 14 mm, 70 mm and 100 mm, high resistance gooseneck-shaped hotwire, CO/CO2, multifunction, high temperature hygrometry, RTD, thermocouple etc. The interchangeable measuring modules are individually calibrated and are automatically recognized by the instrument via the Smart-plus system. As example, the AMI can be equipped with several pressure measuring modules with different measuring ranges. This new system allows evolution according to measurements that must be carried out. info@asstech.co.za Wide light band facilitates reliable detection of both small and large objects Featuring a wide light band, the Leuze RK 46C.DXL VarOS retro reflective sensor is able to reliably detect both small and large objects. Objects can be round, angular or both, with glossy surfaces, have transparent shrink wrapped film or even be totally black, with gaps or with high ambient light levels. These Leuze sensors are ideal for when the objects to be detected or the associated environmental conditions deviate from the norm. The Leuze RK 46C.DXL VarOS retro reflective sensor is particularly effective in this regard as it responds to objects with the entire width of its light band, which gives it the capability to be able to handle interruptions. The wide light band allows for detection over a 45 mm to 60 mm wide area The sensitivity and/or resolution of the sensor can be adjusted easily by means of a button located on the rear housing. And this Leuze sensor features a handy ‘teach me’ function which allows it to be adapted easily between two object sizes greater than 8 mm at the touch of a button. This ensures optimum flexibility of application. The use of this sensor does away with the need for expensive light barriers or multiple individual sensors. Other features include the ability to calibrate for detection of transparent, perforated or small objects as well as the ability to reliably detect even with depolarising media such as foil packaging. bryant@countapulse.co.za
27 <strong>19.5</strong> Testing spring operated pressure safety valves in situ The PreVenTest is a robust, but ingeniously built system for testing all types and sizes of spring operated pressure safety valves ‘In-Situ’, in process and under the normal operating conditions. The portable system enables you to proof the correct working and performance or identify PSV’s in need of repair/ maintenance without plant shutdown. The ‘In-Situ’ PreVenTest system is standard equipped with industrial laptop and is available in two versions; the fully automatic PreVenTest Advance (optionally available in intrinsically safe / ATEX certified version) and the ultralight, battery driven and handcontrolled PreVenTest LTC. Both the Advance and LTC are suitable for the same extended range up to 20 kN and completed with computer registration. The PreVenTest software is an easily operated user-friendly software package that will recognize the set pressure of the valve and will create a detailed test certificate after the test. PreVenTest Advance: - Fully automatic, computer control and operation. - Very universal and versatile character. - Robust portable system. - Prepared and equipped for all brands, types and sizes. Optional features: - ATEX Intrinsically safe version. - 50 kN set for testing without or with limited process / line pressure. admin@atts.co.za New absolute pressure transmitter with different measuring ranges As of now, ifm has added absolute pressure sensors to its versatile portfolio in the pressure sensor range. The new PT05 series with robust metal measuring cell, G 1/4 process connection, M12 connector and analogue output is available in the common pressure ranges up to 10 bar. Absolute pressure sensors operate independently of the surrounding air pressure; that is what distinguishes them from sensors working on a relative measurement principle. The measurement is not influenced by weather and altitude-related fluctuations of air pressure. This is often a decisive factor in vacuum applications, which require a fine pressure control. Absolute pressure sensors do not require ventilation, therefore incorrect measurement due to a blocked exhaust is impossible. In the field of pressure sensors the new units stand out as specialists for ”specific duties“. info.za@ifm.com
