TDK Corporation launches B58101A0851A000, the first in a new line of immersion temperature sensors (ITS), designed specifically for EV powertrain cooling applications. This highly responsive, fully sealed NTC thermistor is engineered to provide fast and precise temperature control, e.g., for oil-cooled systems. Oil cooling is anticipated to become the dominant temperature management method in the […]

Thermistor series features 14-second cooling tme constant for industrial monitoring
TDK Corporation introduces two new NTC thermistors designed for precise temperature measurement in automotive and industrial environments. The L862 and L871 series operate across a temperature range of -40°C to +155°C, with power dissipation rated at 60 mW at room temperature. The L862 features a 2.6 x 6.5 mm sensor element with silver-plated nickel wire […]
What is negative temperature coefficient?
A negative temperature coefficient (NTC) refers to any physical value that decreases as the temperature increases or vice versa. In electronics, NTC usually refers to a material’s decreasing resistance as the temperature rises. This article examines how NTC device performance is quantified and compares with other technologies like resistance temperature detectors (RTDs) and positive temperature […]
What sensors indicate the weather: part 2
With extreme weather conditions, people directly impacted by the pending situation need to know how severe it will be. For hurricanes, the Saffir-Simpson Hurricane Wind Scale provides a rating from 1 (very dangerous winds that will produce some damage) to 5 (catastrophic damage will occur) based on a hurricane’s maximum sustained wind speed. This approach […]
Vented miniature LVDTs for hydraulic and material testing applications
NewTek offers a vented design for its miniaturized series of AC-operated position sensors that provides greater endurance to pressure, temperature, shock, and vibration. These attributes result in greater accuracy and the ability to fit into restrictive spaces when measuring the deformation of samples in test chambers for hydraulics and material testing applications. In geologic […]
What sensors indicate the weather: part 1
Temperature, barometric pressure, humidity, wind speed and direction, and possible rainfall (or snowfall) in specific areas are common indicators of current and future weather conditions. However, other sensor inputs, such as pressure drop, air quality, particulate matter (including dust), and more (storm surge), are frequently required to identify and react to extreme weather conditions. The recent hurricanes […]
What sensors are in a digit?
In this case, the digit is a finger. Advanced robots designed to interact on a personal level with humans will need hands that can sense a variety of interactions. Several sensing techniques could be employed to achieve the right level of dexterity and avoid excessive force — some simultaneously and far less for specific applications. Getting the […]
FAQ on thermistors for temperature sensing
The thermistor is a widely used temperature sensor and an attractive alternative to thermocouples and RTDs — but only in some applications. Temperature is the most commonly assessed and measured physical parameter if you add all the consumer, industrial, commercial, medical, food-related, product tests and measurements and other places where it needs to be sensed. […]
Radiometric version of compact thermal camera core
Teledyne DALSA announced a radiometric version of its MicroCalibir Long Wave Infrared (LWIR) compact camera platform that delivers accurate temperature measurements of +/-2°C or +/-2%. Developed and manufactured in Canada, the small and lightweight MicroCalibir platform is the result of the latest advances made by Teledyne DALSA’s integration of their in-house 12 μm microbolometer pixel technology with […]
What are the seven types of quantum sensors?
The seven types of quantum sensors include chemical sensors, clocks, gravimeters, imaging, interferometers, magnetometers, and thermometers. Several types of quantum sensors are already in use, and more are being developed for commercialization. They can be used in a wide variety of applications from earth sciences to molecular biology and wide band gap power semiconductors. Chemical […]
