Introduction of Security System

October 23, 2013

The security monitoring system employs an electro-magnetic field disturbance principle based on two unshielded (or 'leaky') coaxial cables buried about 10–15 cm deep and located at about 1 metre apart. The transmitter emits continuous Radio Frequency (RF) energy along one cable and the energy is received by the other cable. When the change in field strength weakens due to the presence of an object and reaches a pre-set lower threshold, an alarm condition is generated. The security monitoring system is unobtrusive when it has been installed correctly, however care must be taken to ensure the surrounding soil offers good drainage in order to reduce nuisance alarms.

 

Effectively Using Guard Patrol System

October 23, 2013

The guard patrol system provides a means to record the time when the employee reaches certain points on their tour. Checkpoints or watch stations are commonly placed at the extreme ends of the tour route and at critical points such as vaults, specimen refrigerators, vital equipment, and access points. Some guard patrol systems are set so that the interval between stations is timed so if the employee fails to reach each point within a set time, other staffs are dispatched to ensure the employe...

Pneumatic Control

October 23, 2013

To ensure that the full valve differential pressure can be accepted, it is important to adjust the positioner zero setting so that no air pressure opposes the spring force when the valve is seated. Figure 6.6.13 shows a typical positioner. Commonly, this would be known as a P to P positioner since it takes a pneumatic control signal (P) from the control system and provides a resultant pneumatic control output signal (P) to move the actuator.

Both pneumatics and hydraulics are applications of...

Character of Fiber Identifier

October 23, 2013

Fiber identifiers are handheld fiber optic test instruments for detecting optical signals transmitted through a fiber without disrupting live traffic. They are used in installation, maintenance, rerouting, or restoration to isolate a specific fiber.

The OFI-400 is a rugged, hand-held and easy-to-use fiber optic test instrument designed to detect and measure the core power levels of optical signals on single-mode optical fiber without disrupting raffic on that fiber. The OFI 400 C is designed...

Introduction of LED Light

October 22, 2013
One method (RGB- or trichromatic white LEDs) uses multiple LED chips, each emitting a different wavelength, in close proximity to generate white light. This arrangement allows for the adjustment of the intensity of each LED to "tune" the apparent color of the final color.


LED tube lights are designed to physically fit in fixtures intended for fluorescent tubes. Some LED tube lamps are intended to be a drop-in replacement into existing fixtures. Others require rewiring of the fixtures to remove...
