Kipp & Zonen SMP Series Smart Pyranometers

The Kipp & Zonen SMP Series Smart Pyranometers are designed for measuring short-wave irradiance on a plane surface, which results from the sum of the direct solar radiation and the diffuse sky radiation incident from the hemisphere above the instrument.

Features

  • Internal digital signal processing and interfaces for industrial applications
  • Automatic correction for temperature dependence of the detector sensitivity
  • Built-in bubble levels and adjustable leveling feet

Overview
The Kipp & Zonen SMP Series Smart Pyranometers are high-quality radiometers designed for measuring short-wave irradiance on a plane surface (radiant flux, W/m²), which results from the sum of the direct solar radiation and the diffuse sky radiation incident from the hemisphere above the instrument.

Integration
SMP pyranometers feature internal digital signal processing and interfaces optimized for industrial data acquisition and control systems. Kipp & Zonen has developed a smart interface that features RS-485 Modbus data communication for connection to programmable logic controllers (PLC’s), inverters, digital control equipment and the latest generation of data loggers. Amplified Voltage or Current outputs are also included for devices that have high-level analog inputs or current loop interfaces.

Model Options
All models are available in two versions. One has an analog voltage output of 0 to 1 V, and the other has an analog current output of 4 to 20 mA. They all have a 2-wire RS-485 interface with Modbus (RTU) protocol. Digital signal processing provides faster response times and, with an integrated temperature sensor, corrects for the temperature dependence of the detector sensitivity.

Design
To achieve the required spectral and directional characteristics, SMP Series pyranometers use thermopile detectors and glass domes. All SMPs have built-in bubble levels and adjustable leveling feet. Snap-on sun shields reduce solar heating of the housings. The waterproof connectors have gold-plated contacts.

Questions & Answers
Can the Kipp & Zonen SMP smart series pyranometers be mounted to a Lufft WS-series weather sensor?
Yes, just be sure to mount the pyranometer where it will not be shaded and do not obstruct the wind sensor on the WS-series instrument. There is a mounting rod (CMF1) and bracket (CMB1) for pole-mounting the pyranometer. The Lufft WS sensors have an integrated bracket mount & U-bolts to mount to a pole, but there is a traverse mount available if you want to offset it. https://www.fondriest.com/lufft-ws-series-sensor-traverse-mounting-kit.htm

From Assessment to Angler: Continual Research Ensures Lake Erie Remains a Beacon of Freshwater Fishing

Lake Erie is well known for its abundant recreational fishing. Anglers come from across the country to try their luck at the “walleye capital of the world” and search for other freshwater species, such as bass, perch, and steelhead trout.  As one of the world’s largest freshwater fisheries, much effort is made behind the scenes to maintain fishing opportunities for visitors to enjoy year after year, efforts that often go unnoticed by the public. One of the lake's most important economic and tourism centers is the city of Sandusky, home to the Sandusky Fisheries Research Station . As part of the Ohio Division of Wildlife, the unit serves as a base for assessing fish populations and managing harvest with partner agencies from around Lake Erie.

High Definition Stream Surveys: Informed Management in Local Waterways

When it comes to environmental monitoring, new stream survey methodologies have revealed a great deal about water quality and streambed conditions over time. Such information can be particularly important in leading restoration initiatives and prioritizing management decisions. Historically, stream surveys have been conducted at a single point along the stream, with data then extrapolated for miles up and downstream. However, Brett Connell, Hydrologist and Director of Sales at Trutta Environmental Solutions, started developing a more intensive stream survey format in his master's program in 2010 at the University of Tennessee.

Climate Change and Microplastics: Monitoring Lake Champlain

Most people go to Lake Champlain for its exceptional views and thrilling boating, but it’s also home to a wide variety of interesting aquatic research projects. From studying microplastics to thermal dynamics of the lake, Timothy Mihuc, director of the Lake Champlain Research Institute (LCRI) at the State University of New York at Plattsburgh (SUNY Plattsburgh), has spent his career studying aquatic ecosystems.  As an aquatic biologist, he’s the main investigator on Lake Champlain’s research studies while also managing their grants, employees, and their hands-on buoy work.  Over the years, LCRI has received a number of environmental grants that aid in its monitoring research.
