ADVANCES IN SPEED MONITORING PROMOTES RAIL SAFETY
(ContentDesk) September 24 2003--Why use speed detection devices?
By monitoring speed accurately at each powered axle, it is possible to synchronise speed from each wheel set to ensure smooth and balanced power delivery.
This gives rapid acceleration and braking without wheel spin or slide.
Positive benefits include avoiding excessive power use, damage to wheel sets or track and a reduction in downtime for service attention.All Rowe Hankins speed monitoring systems use magnetic disturbance - the Hall-effect - to generate a pulse that is directly proportional to speed.
This produces a strong signal that cannot be degraded by EMC, RFI and other forms of interference.
The company offers both Hall-effect speed probes and pulse generators.Speed probes are often installed as a retrofit directly to the gearbox, using the cogs on a gear wheel as the target to create the pulsed signal.
These probes cope well with this environment, the magnetic pulse being unaffected by oil, grease or other contaminants.
Service experience with this equipment confirms their extreme reliability with in excess of 10 million hours mean time between failures.
However, engineering problems may prevent this solution in some cases.
For these situations, Rowe Hankins have an alternative, their pulse generator.The Rowe Hankins pulse generator eliminates the engineering difficulties that can occur when retrofitting probes into gearboxes.
They use a precision-engineered target that is fitted, like a top hat, over the end of the powered axle or on the motor shaft.
This target is easy to install and requires no special tools.
It provides a highly reliable and accurate signal that is detected by a Hall-effect sensor that can be located up to 10mm away.
Unlike optical pulse generators, this device is unaffected by contamination, motion or vibration and has a wide band of tolerance to misalignment. The pulse detector can detect both forward and backwards motion, and therefore provides the signalling for rollback protection.
The target also has the capacity for other sensors to be fitted to monitor functions such as vibration and temperature.
Data from these sensors is vital input for on-train monitoring and recording systems that give early warning of potential problems.
This allows timely action to prevent costly long-term damage or component failure. Rowe Hankins speed monitoring products are winning friends around the world.
Metro systems in Shanghai, New York, Washington and Sacramento use them.
You can also find them on French freight locos and on stock in Brazil, Australia and in the UK on the London Underground.
The company has an active R&D department that works with train builders, operators and leasing companies to provide practical solutions to improve safety, maximise uptime and extend service life.For easy editing, high/low resolution images are on the web at ww.ainsmag.co.uk/rh109/3606rh1a.htm.
The Advantage Group Announces the Release of Enterprise Modbus
St. Louis, MO (ContentDesk) January 31, 2006 -- The Advantage Group is pleased to announce Enterprise Modbus, the newest addition to their suite of data center monitoring products.Enterprise Modbus is a web-based application that allows you to monitor devices using the Modbus protocol.
These devices typically include generators, uninterruptible power supplies, static transfer switches and HVAC equipment.
Enterprise Modbus supports both serial (RTU or ASCII) and TCP Modbus protocols.
It can monitor devices from multiple manufacturers.
Enterprise Modbus can be run as a standalone product or integrated seamlessly with Enterprise Device Manager to provide the ability to monitor both Modbus and SNMP devices from the same console.While typical building management systems may start at $50,000, Enterprise Modbus retails for only $8,000.
"The Enterprise suite of products helps to break down the wall between the Facilities and IT groups," explains Dave...

Portable Generators
Portable generators are used in homes and in places where there is no power or the need for power is minimum. Portable generators are generally smaller and are designed to use for a few. A portable generator of 5KW has enough power to keep lights, refrigerators, computers and televisions running for 7 to 8 hours. Portable generators are normally powered by gasoline, diesel, propane or natural gas. They are the most popular of all portable generators.
Gasoline generators are relatively less expensive but require frequent maintenance and have a shorter life span. Gasoline has a short shelf life and cannot be stored for a long time unless treated with stabilizers.
Diesel generators, on the other hand, are fuel-efficient, consume less fuel per kilowatt of power produced, have longer life and require less maintenance. Diesel can be stored for longer periods of time. However, they are harder to start in cold weather and noisy. Portable generators powered by natural gas...
