On 18 January 2010, ABC News reported Trijicon was placing references to verses in the Bible in the serial numbers of sights sold to the United States Armed Forces. [1] The "book chapter:verse" cites were appended to the model designation, and the majority of the cited verses are associated with light in darkness, referencing Trijicon's specialization in illuminated optics and night sights.
[3] Where level must be sensed inside a pressurized vessel, often a magnet is used to couple the motion of the float to a switch located outside the pressurized volume. In some cases, a rod through a stuffing box can be used to operate a switch, but this creates high drag and has a potential for leakage. Successful float switch installations ...
3.4 μm region. All hydrocarbons and their derivatives absorb strongly, due to the C-H stretch mode of molecular vibration. It is commonly used in infrared point detectors where path lengths are necessarily short, and for open-path detectors requiring parts-per-million sensitivity. A disadvantage for many applications is that methane absorbs ...
For use in open air applications, where the sensor cannot be mounted to the bottom of the tank or pipe thereof, a special version of the hydrostatic pressure level sensor, a level probe, can be suspended from a cable into the tank to the bottom point that is to be measured. [3] The sensor must be specially designed to seal the electronics from ...
Simple sight glasses may be just a plastic or glass tube connected to the bottom of the tank at one end and the top of the tank at the other. The level of liquid in the sight glass will be the same as the level of liquid in the tank. Today, however, sophisticated float switches have replaced sight glasses in many such applications.
The Iqos 2.2 was the first commercially launched device under the brand name. [21] In 2023, Iqos products had 28.6 million users in 84 countries. [ 22 ] Among them, the United States , Canada , New Zealand , South Korea , Israel , United Arab Emirates , Ukraine , Belarus , Moldova , Georgia and most European Union countries have chosen to adopt ...
The resistance of the tin dioxide layer, typically in the range of 10 to 500 kΩ in air, can drop to a small fraction of this value in the presence of a reducing gas. [10] This change in resistance (often together with signals of other sensors, e.g. humidity sensor values, for cross-sensitivity compensation) is used to calculate the gas ...
A water in fuel sensor, or WiF sensor, is an electronic sensor used to indicate the presence of water in fuel.It is installed in a fuel filter.When the water level in the water separator reaches the warning level, the WiF sends an electrical signal to the ECU or to dashboard (lamp). [1]
