Aerospace

Thu, 13 Nov 2025 16:25:28 -0800

Application: Aerospace

With the recent occurrence of a door plug blowout on an aircraft in Alaska, we thought it would be interesting to measure cabin pressurization during a flight. To verify that the aircraft cabin pressurization system was working properly, a Precision Barometric Pressure logger was used.

The graph shows a 3 hour flight, from sea level to sea level. Just before takeoff the cabin is slightly pressurized, about 0.1 PSI above ambient, When the aircraft takes off, cabin pressure is gradually reduced to about 10.9 PSI, about the same pressure as at 8000 feet altitude and was held fairly constant until descent. Pressure gradually rises back to 14.8 PSI during descent, and then drops to 14.7 PSI shortly after landing.

Agriculture

Thu, 13 Nov 2025 16:25:28 -0800

Application: Agriculture

What is the temperature underground where your crops grow? We measured the top 30 cm of ground temperatures in mid July day and night so that you could see the interesting characteristics and timing.

The surface temperature was by far the hottest and coldest, and the temperatures farther underground were much more stable. Notice the increasing phase shift with depth: the 30cm-deep waveform is almost 180 degrees (pi radians) out of phase with the surface waveform. The surface reached its highest temperature around 4:00 in the afternoon, while the temperature 30 cm down peaked at 2:30 in the morning, long after the sun had gone down.

HVAC

Thu, 13 Nov 2025 16:25:28 -0800

Application: HVAC

Five data loggers were used to investigate the interactions of a wood stove with the building it is in: 3- Thermocouple, 1- CO2/RH/Temperature/Barometric and 1- Low Pressure logger.

Thermocouple temperatures were recorded in the firebox, the hot air output to the room, and exhaust temperature at the top of the chimney. CO2/RH/Temperature/Barometric pressure was measured around the wood stove. Building pressurization was measured in the same room as the wood stove relative to outdoor pressure. Graphs were visible in realtime as the tests proceeded, with all five loggers shown on the computer screen at all times.

Process

Thu, 13 Nov 2025 16:25:28 -0800

Application: Process

The infrared solder reflow oven was having manufacturing-quality issues so the first thing we checked was the temperature inside the oven. Instead of a stable regulated temperature, the oven temperature was rippling with a 5-degree C oscillation, as shown in the graph immediately below. We found that the thermocouple in the control system was not well thermally coupled to the oven temperature, so that was the first thing to remedy. A tightly-coupled temperature sensor (acheived by removing the thermocouple from its stainless-steel sheath and bonding it to the oven thermal plates with rigid thermal compound) and some improved settings in the PID controller solved this problem.

Vehicles

Thu, 13 Nov 2025 16:25:28 -0800

Application: Vehicles

High CO2 concentration in a motor vehicle can cause dizziness, headache, sleepiness, cognitive dysfunction and slowed reaction time. All of these can adversely affect safety of the driver, passengers and other drivers on the road.

But just how high does the CO2 concentration get? With the windows closed, air conditioning switched on and the air supply set to recirculate (a common scenario when driving in Summer), let’s measure the CO2 concentration in a small generic economy car. We used a CO2 Logger with only the CO2 channel active. The visual alarm level was set to 425 ppm, the normal outdoor ambient CO2 concentration. Test duration was 45 minutes, with only one person in the car. CO2 level rose to 3383 ppm, which is much higher than the acceptable maximum of 1000 ppm.

Water Systems

Thu, 13 Nov 2025 16:25:28 -0800

Application: Water Systems

Case 1: Using Precision Loggers to troubleshoot and fix a small-town water system

The system pulls water from a well that goes dry in late summer, so it has a large water reservoir that is always kept full. It also usually pumps from the well to directly fill a 22-meter (70 ft) water tower that supplies the town. The symptom was that occasionally the tower tank goes empty for no known reason, and the problem was getting worse over time.

The Hidden Dangers of Poor Air Quality in Schools

Viruses and Solvents

Indoor air quality has emerged as one of the most critical issues in schools, influencing not only the health and productivity of students, but also affecting airborne disease transmission. In 2011, a study published in Environmental International¹ highlighted that elevated levels of indoor air pollutants increase the risk of health problems among schoolchildren. Markers, pens, and glues release volatile chemicals, including alcohols and other solvents, which can linger in the air for a long time. This leads to an increased risk of developing respiratory diseases such as asthma and allergies, negatively affecting learning outcomes.

How CO₂ Levels Can Make or Break Your Speech

Decreased Focus

High carbon dioxide concentrations can significantly impair the cognitive performance of both speaker and audience, compromising the presentation’s effectiveness. As CO₂ levels rise above 1000 parts per million, which can happen quickly in a crowded room, decision-making abilities, concentration, and memory recall decrease. The speaker has difficulty staying focused, forgetting key points and struggling to articulate ideas clearly. The audience finds it harder to pay attention, process information, or retain the content of the speech, cognitive effects that can undermine even the most well-prepared presentation.

Don’t Let Your Business Keep Losing Money in These 3 Key Areas

1. Cutting Costs

At the heart of every comfortable indoor space lies an HVAC system, designed to keep a building’s temperature at a comfortable level year-round. When the space becomes too hot, they activate cooling mechanisms, and when it turns too cold, they provide warmth. Unfortunately, it is all too common for the building to be heating and cooling at the same time without anyone knowing about it, not even the people who are supposed to be optimizing and maintaining the system. The result is unnecessary energy usage, extra maintenance, and equipment failure.
