Getting submarines talking to airplanes, finally

TARF communication from the MIT Media Lab

MIT researchers have taken a step toward solving a longstanding challenge with wireless communication: direct data transmission between underwater and airborne devices.

Today, underwater sensors cannot share data with those on land, as both use different wireless signals that only work in their respective mediums.

Radio signals that travel through air die very rapidly in water. (more…)

The media have started asking about climate change

“Climate? Tune in at 10” is on Grist’s Beacon

By Nikhil Swaminathan

President trump on scientist's political agendaOnline  —  “Last week, in the wake of the latest U.N. report, the Washington Post’s Margaret Sullivan issued a challenge to journalists: ‘Climate change, she said, must be kept front and center with the pressure on and the stakes made abundantly clear at every turn.’

“The U.N. report’s alarming message that we have essentially a decade to take meaningful action on warming combined with Hurricane Michael ripping through the Southeastern U.S. ensured that the media couldn’t avoid talking climate change this weekend.

“CNN’s Jake Tapper and CBS’s John Dickerson asked Florida Senator Marco Rubio directly about the impact of climate change on storms like Michael. ABC’s George Stephanopoulos asked White House economic advisor Larry Kudlow if the president would act on warming.

“And in her 60 Minutes interview with President Donald Trump, Lesley Stahl asked him point blank: ‘Do you still think that climate change is a hoax?’ (more…)

Industrial Transmitter for Applications Up to 180 °C (356 °F)

Robust IP65 / NEMA 4 enclosure

EE23-T2Engerwitzdorf, AUSTRIA — The EE23 transmitters measure relative humidity (RH) and temperature (T) and also calculate the dew point (Td) and the frost point temperature (Tf).

The new model EE23-T5 is suitable for a temperature range of -40 °C to 180 °C (-40 °F to 356 °F) and thus expands the application range of the proven transmitter series.

The EE23 series includes models for wall or duct mount as well as different remote probe versions. (more…)

DeFelsko PosiTector Dew Point Meter

PosiTector® DPM & PosiTector® IRT

Positector DPMOnline  —  Dew Point Meters for Environmental Monitoring

The PosiTector DPM family measures a number of climatic parameters including relative humidity, air temperature and surface temperature enabling it to calculate dew point temperature and the all-important difference between surface temperature and dew point temperature (Ts-Td) — a vital parameter for industrial painters.

Uses: Ideal for surface preparation as required by ISO 8502-4, BS 7079-B4, ASTM D3276, IMO PSPC, SSPC-PA7 and US Navy NSI 009-32. (more…)

Mold Inspection Sciences Texas New Investment in FLIR E6 Infrared Camera

Expanding Testing Capabilities

FLIR E6 thermal cameraAUSTIN, TX. USA –(SEND2PRESS NEWSWIRE) — Mold Inspection Sciences Texas (MISTX) has announced the rollout of FLIR E6 Infrared Cameras across all Mold Inspection Sciences Texas service areas.

The introduction of this advanced, non-invasive technology allows MISTX field teams to zero in on and identify potential sources of moisture during testing and sampling investigations.

The FLIR E6 has both a thermal and a visible camera that are used together to produce the patented FLIR image enhancement, called Multi-Spectral Dynamic Imaging, or MSX®. By enhancing thermal with visible details, the camera produces crisper imagery and greater perspective on the scene. (more…)

The PosiTector® IR Thermometer

Infrared Thermometer

Positector IRTOnline  —  The PosiTector® IRT measures surface temperature.

The PosiTector IRT has a distance to spot ratio and a button activated laser pointer for precise and accurate surface temperature measurement.

Features

  • Button-activated laser pointer for accurate targeting
  • Selectable emissivity values – choose from 7 preset material options, set a custom emissivity value, or adjust to a known temperature
  • Statistics Scan mode – continually displays/updates average, standard deviation, min/max surface temperature and number of readings while measuring one reading per second
  • Certificate of Calibration showing traceability to NIST included (Long Form)
  • 5.7:1 distance to spot ratio – ideal for measuring large areas
  • Smart Trend indicators identify rising, falling or stable readings

Comparing the Performance of Optical Gas Imaging Cameras

Introduces Noise Equivalent Concentration Length

tech article for downloadMeer, Belgium  —   FLIR Systems has published a technical paper that introduces the benefits of using Noise Equivalent Concentration Length (NECL) as a useful method to measure the performance of an Optical Gas Imaging (OGI) camera.

Optical gas imaging (OGI) is widely used in the oil and gas industry to detect leaks.

Operators of gas distribution networks, processing plants, pipeline facilities, terminals, and offshore platforms want to find and repair leaks to prevent explosions, minimize loss of their product, and comply with environmental and safety regulations. (more…)
