Overview
The Vaisala WSP150 Surge Protector is a compact transient overvoltage suppressor designed for outdoor use. It can be used with all Vaisala wind and weather instruments. The WSP150 offers three-stage protection against surge currents up to 10 kA entering through the power and signal cables.
Mechanics
The Vaisala WSP150 Surge Protector has four channels, two of which are dedicated to power lines and two for data lines. Each channel uses a three-stage protection scheme as follows: first, there are discharge tubes, then voltage-dependent resistors (VDR), and finally, transient zener diodes. Between each stage, there are either series inductors or resistors. Both differential and common mode protection is provided for each channel: across the wire pairs, against the operating voltage ground, and against the earth. The WSP150 also includes noise filtering against HF and RF interference.
Applications
Vaisala recommends using the WSP150 when wind and weather instruments are installed on top of high buildings or masts and in open grounds, that is, anywhere with an elevated risk of lightning. Also, use the WSP150 if the cable length exceeds 30m or if users have unshielded, open-wire lines.

Vaisala WXT520: Weather station designed with monitoring systems in mind
The world’s weather is full of surprises. That makes a quality weather station a valuable piece of technology for monitoring systems. Vaisala's WXT520 multiparameter weather station is built with monitoring systems in mind. It monitors six weather parameters in real time, so users have the numbers on an unexpected rain storm or turbulent wind event. It can be a means of understanding weather events that caused a flush of nitrogen into a river or low water levels in a lake. What’s more, with the help of a data logger and telemetry system, it can deliver that information to one’s desk so she can stay dry and keep an eye on the data during a storm. Three core components make up Vaisala’s WXT520 weather station.

Restoring North Texas Streams to Historical Flows
North Texas is one of the fastest-growing regions in the state, an area that is expected to face increasing water needs. In order to meet these demands, the Upper Trinity Regional Water District ( UTRWD ) is building Lake Ralph Hall near Ladonia in southeast Fannin County, Texas. The lake has been in the works since 2003, with construction finally beginning in 2021. The population of the UTRWD is expected to grow 5-fold over the next 50 years, leading to increased water use. Ed Motley, Program Manager with the UTRWD stresses that even with conservation and reuse, new sources like Lake Ralph Hall are essential to meeting near-term and long-term water needs to support regional growth.

Science for Science’s Sake: Monitoring Ocean Energy Availability and Gulf Stream Dynamics
Scientific research often begins with a question, sometimes driven by a specific goal or application, but many scientists believe in science for science’s sake. Marine environments and physical dynamics like the Gulf Stream are popular fields of research due to their complexity and importance, presenting a unique opportunity to learn more about previously unexplored phenomena. Environmental researchers, in particular, see the value in these ecosystems, but many also grew up with a passion for the natural world, and choosing a field that allows them to interact with and learn about the environment around us is an easy choice.
