Super-classes tern-ssn:Hygrometer c

Hair hygrometer c

IRI https://w3id.org/tern/ontologies/ssn/HairHygrometer
Description A hygrometer that measures relative humidity by means of the variation in length of a strand of human hair. The length variation of a properly treated hair is 2%–2.5% when the humidity changes from 0%–100%. The hair hygrometer is considered to be a satisfactory instrument in situations where extreme and very low humidities are seldom or never found. The rate of response is very dependent on air temperature; the lag time increases with decreasing temperature. For air temperatures between 0° and 30°C and relative humidities between 20% and 80%, a good hair hygrometer should indicate 90% of a sudden change in humidity within about three minutes.
Super-classes tern-ssn:Hygrometer c

Heat flux sensor c

IRI https://w3id.org/tern/ontologies/ssn/HeatFluxSensor
Description A heat flux sensor is a transducer that generates an electrical signal proportional to the total heat rate applied to the surface of the sensor. The measured heat rate is divided by the surface area of the sensor to determine the heat flux.

Super-classes sosa:Sensor c

Lithium chloride heated condensation hygrometer c

IRI https://w3id.org/tern/ontologies/ssn/LithiumChlorideHeatedCondensationHygrometer
Description The equilibrium vapour pressure at the surface of a saturated lithium chloride solution is exceptionally low. As a consequence, a solution of lithium chloride is extremely hygroscopic under typical conditions of surface atmospheric humidity; if the ambient vapour pressure exceeds the equilibrium vapour pressure of the solution, water vapour will condense over it (for example, at 0 °C water vapour condenses over a plane surface of a saturated solution of lithium chloride to only 15 %rh).
Super-classes tern-ssn:Hygrometer c

Mercury barometer c

IRI https://w3id.org/tern/ontologies/ssn/MercuryBarometer
Description A mercury barometer has a vertical glass tube closed at the top sitting in an open mercury-filled basin at the bottom. Mercury in the tube adjusts until the weight of the mercury column balances the atmospheric force exerted on the reservoir. High atmospheric pressure places more force on the reservoir, forcing mercury higher in the column. Low pressure allows the mercury to drop to a lower level in the column by lowering the force placed on the reservoir. Since higher temperature levels around the instrument will reduce the density of the mercury, the scale for reading the height of the mercury is adjusted to compensate for this effect. The tube has to be at least as long as the amount dipping in the mercury + head space + the maximum length of the column.

Optical rain gauge c

IRI https://w3id.org/tern/ontologies/ssn/OpticalRainGauge
Description This type of gauge has a row of collection funnels. In an enclosed space below each is a laser diode and a photo transistor detector. When enough water is collected to make a single drop, it drops from the bottom, falling into the laser beam path. The sensor is set at right angles to the laser so that enough light is scattered to be detected as a sudden flash of lights. The flashes from these photodetectors are then read and transmitted or recorded.

Thermistor c

IRI https://w3id.org/tern/ontologies/ssn/Thermistor
Description A thermistor is a type of resistor whose resistance is dependent on temperature, more so than in standard resistors. The word is a combination of thermal and resistor. Thermistors are widely used as inrush current limiters, temperature sensors (negative temperature coefficient or NTC type typically), self-resetting overcurrent protectors, and self-regulating heating elements (positive temperature coefficient or PTC type typically).

Thermocouple c

IRI https://w3id.org/tern/ontologies/ssn/Thermocouple
Description A Thermocouple is a sensor used to measure temperature. Thermocouples consist of two wire legs made from different metals. The wires legs are welded together at one end, creating a junction. This junction is where the temperature is measured. When the junction experiences a change in temperature, a voltage is created. The voltage can then be interpreted using thermocouple reference tables to calculate the temperature.

Time domain reflectometer c

IRI https://w3id.org/tern/ontologies/ssn/TimeDomainReflectometer
Description Sensors that use the Time Domain Reflectometry (TDR) are somewhat similar way to FDR probes, but the mechanics behind the measurement system are different. TDR sensors use parallel rods, acting as transmission lines. A voltage is applied to the rods and reflected back to the sensor for analysis. The speed or velocity of the voltage pulse along the rod is related to the apparent permittivity of the substrate (Blonquist 2005-A). In relatively wet soil the velocity of the pulse is slower than in drier soil. Examples of this sensor include the Campbell Scientific CS650 and the IMKO Trime-Piko 32.
