Adjustable torque wrench
An adjustable torque wrench includes a driving head having an arm received in a shank, and a follower and a spring received in the shank and guided to move along the shank. The follower may be moved to adjust the spring force against the arm.
Hydraulic torque wrench
A hydraulic torque wrench is a tool made to apply torque on a fastener to accomplish appropriate tightening or loosening of a connection through the use of hydraulics methods. A torque wrench is applied to the nut either directly or in conjunction with an impact socket. Hydraulic torque wrenches is a prearranged, with controlled amount of torque to a properly lubricated fastener.
Torque tester | Torque Transducer
A torque tester is utilized as a quality check device to test or calibrate torque controlled tools. This includes electric screwdrivers, air screwdrivers, pulse tools, electronic torque wrenches, click torque wrenches, dial torque wrenches, cordless screwdrivers, nutrunners, and torque screwdrivers. Present sophisticated torque testers include the ability to measure in clockwise and counter-clockwise directions, convert to engineering units (In Oz, In Lb, Ft Lb or Foot-pound force, Nm or Newton meter, cNm, Kg Cm, g Cm, Kg fm), 3 modalities of operation (Peak, 1st Peak, Track), and include a NIST certificate.
Torque wrench
A torque wrench is a tool utilized to accurately adjust the torque of a fastener such as a nut or bolt. It’s commonly in the form of a socket wrench with specialized internal mechanisms. A torque wrench is utilized wherever the tightness of screws and bolts is important. It permits the manipulator to measure the torque (rotational force) applied to the bolt so it can be corresponded to the specifications.
The Space Tools That Fixed The Hubble
Nothing is easy in space.Imagine trying to use a caulking gun while wearing hockey gloves and bobbing in zero gravity.To repair or install modules in extreme conditions (temperatures ranging from 150 degrees below zero to 150 degrees Fahrenheit) NASA astronauts need special tools.
Short on time, the engineers turned to commercially available tools that could be modified for space.
“Whenever we can start with something like that, it makes our job easier,” said Russell L. Werneth, Goddard EVA manager for the Hubble Space Telescope and Shuttle Return to Flight.
REMOTORING
The properties of motors should be thoroughly understood to avoid some chronic misconceptions. Before deciding to remotor, it is wise to know what you have and what improvements are available for replacement. A thorough ANALYSIS OF MOTOR PERFORMANCE is required to avoid disappointment and wasted time, effort and money. Each motor has its pros and cons, dependent on application. Is it worth performing major surgery on a loco, destroying the original mount, only to find nothing was gained or that things are worse ?
PHYSICS | MECHANICS FORCE | ENERGY or WORK | Torque
A short discussion of some basic physics may help explain other discussions or just confuse them more. With a degree in years of experience as an Automation Engineer, sometimes I overlook the fact that not everyone has a background to understand all the math and jargon. An attempt to clear things a bit is presented.
DYNAMOMETER
There is much hype on the quality of new motors used in expensive locomotives, but very little data on their true performance or ratings.
Used to measure the output of a prime mover (motor or engine), an electric motor dynamometer consists of three parts: a brake to measure torque applied as a resisting force to the shaft, a tachometer to measure RPM and an ammeter to measure current.
SCADA Systems
SCADA systems are used to control dispersed assets where centralized data acquisition is as important as control . These systems are used in distribution systems such as water distribution and wastewater collection systems, oil and natural gas pipelines, electrical utility transmission and distribution systems, and rail and other public transportation systems.
SCADA systems integrate data acquisition systems with data transmission systems and HMI software to provide a centralized monitoring and control [..]
Industrial Control System – Network Components
There are different network characteristics for each layer within a control system hierarchy. Network topologies across different ICS implementations vary with modern systems using Internet-based IT and enterprise integration strategies.
Control networks have merged with corporate networks to allow control engineers to monitor and control systems from outside of the control system network. The connection may also allow enterprise-level decision-makers to obtain access to process data. The following is a list [..]
