poisoned at the inlet of the carbon filter, again reducing measurement accuracy. The MS02 has no electrolyte, so is immune from poisoning and doesn’t leach into water, safeguarding accuracy. Furthermore, at the outlet where zero-chlorine is measured, the MS02 is immune to polarization. This is because the MS02 is combined with an electrolyte filled chamber away from the measurement cell which provides a floating zero point. This avoids having to add a costly chlorine source to the process. These advantages are evidenced by the fact that Bürkert customers have reported MS02 Chlorine Cubes working perfectly for over two years in drinking water applications with no maintenance or recalibration. Consequently, users can expect a ignificant reduction in operating expenditure (OPEX).
A STANDARDISED DESIGN WITH ADDED FLEXIBILITY
Importantly for integrators, OALAB is a plug and play solution, fully pre-mounted and wired. The system can measure pH, ORP (redox), conductivity, free chlorine, zero-chlorine, chlorine dioxide, turbidity, iron, nitrate and SAC (UV254) in an installation around 1-metre wide – saving considerable space compared to alternatives. Furthermore, it only requires 18 litres per hour for sampling, lowering volumes and reducing wastage. OALAB also features an active data logger, while enabling remote monitoring and diagnostics. Consequently, operators can receive almost immediate technical support from Bürkert. Its ME43 industrial gateway is compatible with protocols such as Profinet, Ethernet and Modbus TCP. Until now, traditional amperometric sensors and colorimetric analysers have placed multiple limitations on the monitoring of industrial GAC filters. Bürkert’s OALAB with the MS02 Chlorine Cube supersedes these technologies, providing a faster, more accurate solution that better protects products, equipment and profitability.

PROPORTIONAL VALVE WITH PRESSURE COMPENSATION ACHIEVES COMPACT FOOTPRINT FOR MEDICAL AND ANALYTICAL DEVICES
valves, and can handle oxygen, air, natural gases, and fuel gases. The valve’s compact dimensions and low power consumption make it well-suited for applications in analytical and medical devices. The Type 2852 proportional valve is up to 50 per cent smaller than alternative pressure compensation valves, giving OEMs greater flexibility in the design of their devices. The valve also features a streamlined form, which includes direct inlet pressure control without the requirement for a separate pressure controller. This feature optimises flexible device integration and enables faster, simpler installation. Despite its compact dimensions, the Type 2852 delivers high flow rates, with a kVs flow coefficient value of 0.2 m³/h, and a pressure range up to 7 bar. The new valve design also provides high performance positioning, achieving a repeat accuracy deviation of less than one per cent, and response sensitivity deviation lower than 0.1 per cemt. Featuring an expansive setting range of over 1:500, the single width design covers the equivalent scale of orifice sizes between 1mm and 3mm.

ürkert Fluid Control Systems has released a new 2-way proportional valve with pressure compensation. The Type 2852 offers high flow rates as well as higher pressure operations compared to equivalent size
Integrated within medical devices, the excellent dynamics of the Type 2852’s solenoid valve also optimises patient comfort. In ventilator applications, the ability to control of a wide pressure range, combined with a short reaction time, offers safe patient ventilation, removing the need for higher flow rates. As well as integration in respiratory devices, the Type 2852 is also ideal for laparoscopy devices, environmental analysis and material analytics machines. Meeting its high performance in flow and pressure rates, as well as accurate positioning control, the valve is up to 70 per cent more energy efficient than traditional proportional valves with pressure compensation. In addition to reducing energy demands, the Type 2852’s optimised efficiency capability helps ensure a longer operating time for battery-powered devices. The valve also operates with reduced heat input, increasing reliability and helping to extend service life. Constructed from a stainless steel body with FKM sealing, the Type 2852 can be specified with a flange or cartridge fitting, with wires, connectors, or pins, and the valve operates with a 12 or 24 V DC input. The Type 2852 is certified for use with oxygen, food & beverage/hygiene with USP Class VI, as well as DVGW certification for use with hydrocarbons (flammable gases).
