The Z-200 unit allows almost any number of analogue or
digital input values to be wirelessly transmitted to a remote
receiver with either analogue 4-20mA, 0-10V , Ethernet or
RS232 outputs.
The transmitter unit has one universal analogue input but the
system can be expanded through the use of the optional
slice I/O modules.
These modules connect automatically via the DIN rail
mounted bus connector allowing the easy addition and
removal of extra I/O.
The built-in display allows local monitoring of the individual
inputs and outputs, a ....etc

Wiper Motor, the power source of the wiper blade, is the core of the whole wiper system. Therefore, the quality of the wiper motor must be guaranteed to ensure its performance. The wiper motor is a permanent-magnet direct current (DC) one. It is equipped on the front windscreen glass with the mechanical parts of the worm gear. The worm gear functions to slow down and increase torque. Its output shafts spur four-bar linkage, by which the movement is changed from rotary to swinging.

Three-brush structure is adopted to make speed change more conv ....etc

How does a lux meter works?
This may not be all about how it works, but some background is good too.A lux meter is a device for measuring brightness, specifically, the intensity with which the brightness appears to the human eye. This is different than measurements of the actual light energy produced by or reflected from an object or light source. The lux is a unit of measurement of brightness, or more accurately, illuminance. It ultimately derives from thecandela, the standard unit of measurement for the power of light. A candela is a fixed am ....etc

A klystron is a specialized linear-beam vacuum tube, invented in 1937 by American electrical engineers Russell and Sigurd Varian, which is used as an amplifier for high radio frequencies, from UHF up into the microwave range. Low-power klystrons are used as oscillators in terrestrial microwave relay communications links, while high-power klystrons are used as output tubes in UHF television transmitters, satellite communication, and radar transmitters, and to generate the drive power for modern particle accelerators. ....etc

When piezoelectric materials are under pressure, the pressure causes changes along the surface of the material, these pressure differences result in compression along one surface and strain along the other one. As a result, the positive charges collect on one side of the material, and the negative charges collect on the opposite side. This generator effect converts mechanical energy into electricity. In the reverse piezoelectric effect, used in buzzers, applying an electrical field causes the length of the surface to change and converts electri ....etc
