pump systems, pipes & valves Ultrasonic sensor for remote water level measurement
S
enix ToughSonic Chem range of ultrasonic sensors, in service around the world in some of the most demanding and corrosive industrial environments, are available from Instrotech in South Africa. They measure a wide variety of materials including diesel fuel levels in rail locomotives and levels of liquid chemicals in the paper and food processing industries. ToughSonic Chem sensors are also used in object detection and other non-liquid level applications where corrosive gasses are present. ToughSonic Chem sensors are sealed in Kynar PVDF housings for protection against solvents and can withstand total
immersion in harsh chemicals, both acids and bases, without damage. They include the same full-epoxy potting, heavy-duty electronics, ruggedised-piezoelectric transducers, and UV-resistant cables that make these sensors robust and durable. Several fully configurable and simultaneous outputs are provided, including serial data (RS-232 or RS-485, by model), analogue (0-10VDC and 4-20mA) and switches (configurable as sinking or sourcing). Up to 32 RS-485 models can be used in a multi-drop addressable network using the Modbus protocol – a standard feature. ToughSonic Chem sensors offer the configuration and operational flexibility that all Senix sensors provide. Powerful extended features can be configured using SenixView software. ToughSonic General Purpose sensors can also be used in liquid level applications where chemical resistance is not required. INSTROTECH Tel: (010) 595 1831 sales@instrotech.co.za www.instrotech.co.za
Introducing extremely quiet, dry pumps
T
he HiScroll models from Pfeiffer Vacuum’s new range of scroll pumps are oil-free, hermetically sealed vacuum pumps with high nominal pumping speeds of six to 20m³/h. The new pumps are characterised by their compact design and quiet, low-vibration operation (<47dB[A], and <42dB[A] in stand-by mode). Condensation in the vacuum pump is avoided due to its excellent water vapour tolerance, thanks to the two-stage gas ballast. With these features, the pumps are ideal for use in many applications in analytics, biomedicine, pharmaceuticals as well as research and development. They are used in mass spectrometry, electron microscopy, surface analysis, accelerators and laboratory applications, but also in the semiconductor industry, coating processes and gas recovery. The HiScroll’s active temperature control ensures optimal cooling and guarantees the lowest noise level. The new scroll pumps have the lowest noise emissions in their class. These dry pumps can also be easily connected to other Pfeiffer Vacuum products, such as turbopumps, or operated by higherlevel controls via the RS-485 or ProfiNet interface. An intelligent interface makes it possible to define specific pressure ranges or a rotation speed setting mode, so that the pump can be optimally adapted to suit the application. This minimises wear in the pump, resulting in longer service time intervals. The proven quality of Pfeiffer Vacuum products with first-class, durable
components also ensures a long service life as well as lower operating costs. The pumps are easy to maintain, which not only reduces the time to service but also ensures the highest level of reliability. The integrated safety valve and the selfregulating operation of the pump guarantee safe and reliable use. The powerful motor is up to 15% more efficient than conventional drives. This ensures outstanding performance while keeping temperatures low, which in turn simplifies the cooling of systems and plants.
T
he vacuum-safe blocking or regulating and dosing of gas flows requires valves which meet both the process specific as well as the vacuumspecific requirements. In addition to the basic function of the valve, valve parameters such as structure and size, drive type, operating and closing times, service life or materials determine the selection. Pfeiffer Vacuum stocks a wide range of valves which fulfil both vacuum requirements, as well as those of the specific tasks and thus offers reliable solutions for almost all processes. In addition to manually operated valves, pneumatic, electropneumatic, electromagnetic and motor operated valves for automation processes are also offered. The company places great importance on user friendliness, such as ergonomic grips and low amount of force. Integrated position sensors and a service life of up to 10 million cycles will make your daily work easier.

Pfeiffer Vacuum proudly distributed by Air & Vacuum Technologies
he KNF Controlled Lab Vacuum pump system has become essential and useful for precise vacuum in a wide variety of lab applications such as vacuum desiccation, vacuum gel drying or vacuum filtration. This pump system can be remotely operated from a portable terminal, so that the system can be stored under a bench or in another safe place. The SC950 has the advantage of offering short processing times, high accuracy and higher rates of recovery, even for low boiling point solvents.
