Durability and reliability in level measurement
Accurate, often continuous level measurement is a crucial part of materials management and a wide range of solutions are available to ensure that it occurs. Eugene McCarthy reports.
Genaue, oft kontinuierliche Messtechnik ist ein entscheidender Teil des Materialmanagements und viele verschiedene Lösungen sind verfügbar, um zu sichern, dass sie erfolgt.
Des mesures de niveau précises et souvent continues constituent un élément crucial de la gestion des matériaux et une vaste gamme de solutions sont disponibles pour s’en assurer. Selon Eugene McCarthy.

he new CAP-300 Series from Gems Sensors & Controls is a durable and reliable point level sensor designed to perform over long periods of time under the
most rugged coolant applications. “With the launch of the CAP-300, Gems
is excited to offer the best-in-class solution,” states Kevin Castonguay, integrated marketing programmes manager. “After spending over two years consulting with industry leading customers and conducting rigorous testing, we are confident that this is the most reliable point level sensor on the market. The CAP- 300 is unique in that it operates in a frequency range which minimises the effects of the conductivity of the media to ensure long-term performance and the sealed design prevents any fluid intrusion,” he added. The CAP-300 requires nearly zero maintenance, is small in size (2-in in length), tolerates coating and will remain reliable even in the standby mode. In addition, it is compatible with temperatures up to 125°C, comes with variety of mounting types and electrical connections, and is easy to install and maintain. Gems has also launched the XM/XT-300 and XM/XT-700 level sensors designed
for where space is at a premium or tighter resolution is important. “These new products are essentially the
blending of two level stalwarts for Gems, the LS-300/700 point level switch and XM-800 continuous level transmitter,” said Tim Kelley, product sales manager. “By taking the best of both worlds, we
now can offer our customers a compact sized, continuous level transmitter option.” The XM/XT 700 series combines the
durability of metal with a compact design for restricted spaces. These compact units feature the rugged durability of stainless steel or brass construction in a lightweight package - making it ideal for broad range of applications where shallow tanks and reservoirs are used in the process. For Baumer, the correct level measurement
solution depends on the job in hand, so when looking for the right measuring technology and the right product the company says three questions must be answered: is it continuous measurement, or knowing when a limit is reached? Is it measuring solids or liquids? Is it contact-free measurement or in contact with the product? The company also investigates user
conditions such as the geometric surroundings and other aspects such as foaming or turbulence, as well as the chemical/physical properties of the substance to be measured. Cleaning standards are an important consideration, too, as is the degree of precision needed in the process. Based on this information,
the company will make its recommendation. For example, an ultrasound solution is often ideal for applications in pharmaceuticals, food and beverage processing, wastewater treatment, and gravel works. Depending on the size of the sensors
