Using Thermopiles with NI Hardware What is a thermopile and how do I use a thermopile with NI hardware like DAQ devices or modules? Solution: A thermopile is an array of several thermocouples connected in series. A thermopile with N thermocouples will output a voltage N times bigger than the one produced by a single thermocouple, increasing the sensitivity of the transducer. With enough elements in the thermopile, a useful voltage can be generated in order to control another process. This type of transducer is often used to measure heat flux. Depending on the voltage specification of the thermopile, it can be used with either a temperature input or a voltage input device.

Temperature-dependent sex determination The thermosensitive, or temperature-sensitive, period (TSP) is the period during development when sex is irreversibly determined. It is used in reference to species with temperature-dependent sex determination, such as crocodilians and turtles. The TSP typically spans the middle third of incubation with the endpoints defined by embryonic stage.

Thermometer basics: Taking your child's temperature Digital thermometers. These thermometers use electronic heat sensors to record body temperature. They can be used in the rectum (rectal), mouth (oral) or armpit (axillary). Armpit temperatures are typically the least accurate of the three. Digital ear thermometers (tympanic membrane). These thermometers use an infrared ray to measure the temperature inside the ear canal. Keep in mind that earwax or a small, curved ear canal can interfere with the accuracy of an ear thermometer temperature. Temporal artery thermometers. These thermometers use an infrared scanner to measure the temperature of the temporal artery in the forehead. This type of thermometer can be used even while a child is asleep. Digital pacifier thermometers and fever strips are not recommended.

Bright Hub Engineering Thermistors are semiconductor devices that are used to measure temperature. The name comes from a combination of the words resistor and thermal.Thermistors have an electrical resistance that is proportional to temperature. From a general physics course on electricity and magnetism, you may have learned that this is a property typical for all conductors.hermistors are temperature sensors that have a resistance proportional to their temperature. This property makes them useful for functioning as safety devices in circuits or as probes that physicians can use during surgery.

- Resistance thermometers measure temperature of an. object based on changes in electrical resistance of the. sensing element. Two types of resistance thermometers are. commonly used: thermistors and resistance temperature. devices (RTD). A thermistor uses a semiconductor as the sensing. element. The electrical resistance of the semiconductor, made mostly from metallic oxides (e.g., NiO), decreases. sharply as the temperature increases.

What is Thermoplastic? A thermoplastic is a type of plastic made from polymer resins that becomes a homogenized liquid when heated and hard when cooled. When frozen, however, a thermoplastic becomes glass-like and subject to fracture. These characteristics, which lend the material its name, are reversible.

Thermochromic Thermochromic inks are temperature sensitive compounds that temporarily change color with exposure to heat. The ink is colored at room temperature, becoming translucent when exposed to heat and revealing the underlying graphic. They can be mixed with other colors to create a two-tone effect.ue to the nature of Thermochromic ink, the color that is revealed must be lighter than the color it is changing from. Exact PMS matches are not possible. Design detail can affect color deposit and change values.
