Pulsar R80 – Setting New Standards for Non- Contact Radar
Introducing the Pul- sar® Model R80 – 80 GHz FMCW Radar Level Transmitter with FMCW technology and an 80 GHz operating frequency for superior performance, smaller antennas and en- hanced accuracy. The
Pulsar R80 brings a sophisticated simplicity to Magnetrol’s best-in-class radar portfolio. Furthermore, Magnetrol’s configuration wizards and proactive diagnostics make commissioning and troubleshooting easier than ever. The Model R80 is minimally affected by turbulence, foam, or excessive vapours, often the downfall of ultrasonic transmitters and some radar products. The smaller antennas and narrower beam angles allow it to be installed into vessels with smaller process connections and those with internal obstructions that must be avoided.
Key Features:
• Multivariable two-wire, 24 VDC loop-powered transmitter for level, volume, or flow • 80 GHz signal with beam angles as narrow as 4 degrees
• Measuring range of 30 meters (100 feet) • Proactive diagnostics and troubleshooting tips • Transmitter head replaceable without breaking process seal
• SIL 2 compliant with 92.3% SFF • Global hazardous area approvals

ADVERTORIALS Variable speed actuation reduces maintenance
The electric actuator for valve control spans two different disciplines: the ‘intelligence’ of managing analogue or digital control signals and feedback, and the creation of ‘brute force’ using linear or rotary motion to open / close different valve types. These two disciplines are generally considered separ- ately throughout the life of the actuator, whether it be in the initial design stage of the controls, or the skill requirements for plant installers and maintenance teams. AUMA Actuators Lim- ited design solutions which reflect these different disciplines by creating a modular actuator solution in which the control
head is separate from the motor gearbox drive unit, using a common interface to connect the two components. Using this interface throughout its product range means that different control heads, whether mechanical (AM Controls) or digital (AC Controls), can be bolted to different drive units.

Custom made rotary valves and diverter valves for the dairy industry
Dairy products are an important source of vitamin D, calcium, and protein for human beings young and old. The dairy processing industry is an innovative one and will continue to come up with healthy new products for the world to enjoy. As rules and regulations on hygiene and (food)safety will undoubtedly become tougher in the future, we are providing an extensive range of sanitary rotary valves and diverter valves specially designed to meet the highest dairy manufacturing standards today as well as in the future. The MZC-Dairy, MZC-II, 2/3-TDV are examples of sanitary rotary valves and diverter valves specially designed to meet the high dairy industry standards. See our dairy industry page at
dmnwestinghouse.com for more information about our USDA accepted rotary valves and diverter valves.

Ventilation Control of the ”Södra länken” Tunnel System: Subterranean motorway gets upgraded by ECO PHYSICS nCLD AL2
Södra länken (The southern link), is a motorway, which is connecting Essingeleden, Stockholm with Värmdöleden, Nacka and partially runs underneath the city. In total, Södra länken is approximately 6 km long, while about 4.5 km lay underground. Considering the distances, Södra länken therefore is the third largest urban, underground motorway Europe, only exceeded by the M30 motorway in Madrid and the Blanka tunnel in Prague. On both ends, a ventilation tower is installed, in order to guarantee continous air interchange. The construction started in 1997 and its opening took place in 2004. The reason for its creation was a law implementation from the 1990s, which did not allow a conventional motorway near to the residential areas, due to air pol- lutants and noise disturbance (
https://en.wikipedia.org/wiki/S%C3%B- 6dra_l%C3%A4nken).
According to European regulations, this systems should contain chemiluminiscence based instruments. In 2018/2019 the old systems (ECO PHYSICS CLD 700AL) were replaced. Considering the road-side
traffic monitoring reference in downtown Hong Kong, the latest model, ECO PHYSICS nCLD AL2, was chosen. This decision was made due to the demanded specifications (lag time 3 sec., resolution 0.4 ppb, 1Sigma < 0.2 ppb) and the implemented, second gas flow channel. Simultan- eous collection of NO, NOX and NO2 values were suddenly possible. Additionally, all essential components come with their own PCB, which allows communication with the mainframe and share real time per- formance data (displayable on the diagnostic output screen). Each nCLD AL2 is integrated into a rack system, which draws sample gas from several measuring points. The sample lines are up to 500m in length and are equipped with an automated pump/valve system. In total, 42 sample points are spread over the tunnel system. The maximum tolerated NO2 conecentration is 400 µg/ m3 (1 h avarage), wich is lower than in for instance the later ”North link” in Stockholm, where the value is 1000 µg/ m3. In fact, for different reasons, the NO2 has increased over time, and for short periods the values will nowadays be considerable higher than 400 µg/ m3 in different parts of the tunnel.
Reasons given are the in- crease of diesel vehicles and the higher Ozon concentra- tions in the ambient air.
