Introduction to Wireless• Conventional Monitoring Conditions
– Long conduit runs between sensors and control room– Cost of materials- estimated $100/ft to run conduit or
cable– Lack of resources to do maintenance
6
• The reality with wired solutions– Long distances from critical monitoring– Large obstructions can make wiring impractical or
impossible– Processes or equipment need monitoring in use– No power available in remote applications– Expense

position/control• Remote process set-up• Temporary
installations• Wired alternative
Application Examples
19
Wireless best fit when…• Manually collected data: Wireless can eliminate the need to send
technicians into the field to read gauges• "Must have" measurements: Environmental or safety regulations may
require additional measurements. Wireless allows the easy placement of instruments where needed.
• Need for diagnostics: Many plants have hundreds of field devices. Wireless allows access to diagnostic information in certain of these areas
• Temporary Monitoring: process may only need a short ( 1-3 months ) monitoring. Wireless allows easy, fast, and inexpensive install for these requirements
• “Want to have" measurements: Wireless permits adding instruments in locations that could not previously be justified.
• Long distances involved: Wireless can eliminate the need for long cable runs and trenching to connect tank farms and similar assets spread over a wide area.
20
Wireless best fit when… • Many pumps and motors: Plants often have hundreds of pumps and
motors. And while continuous condition monitoring is noble in concept, wiring vibration sensors to all of them would be prohibitive. Wireless allows an easy connection.
• Extreme environments: Hot, dangerous and/or hazardous environments make it difficult to install instruments and run wire. Wireless minimizes the problem.
• Crowded environments: Wireless eliminates the need to snake new wires through crowded enclosures and conduit.
• New wiring is too expensive: Installed costs of $50 to $100 per foot can make adding new wired measurement points cost-prohibitive.
• Need for feedback: Manual valves that have no position feedback can cause safety problems. Wirelessly monitoring can cost as little as 10%of a wired solution.
• No other way: Wireless works for mobile assets, remote sites and rotating equipment where using wired instruments is impossible or impractical.
21
Standard terms and definitions• WIBnet™ - wireless-information-backbone. Network technology
allowing flexible, secure and scalable peer-to-peer connectivity of wireless data.
• Industrial-grade –This means temperature , vibration, humidly specs, certification to at least Class I Div 2 , and superior power options and packaging.
• Event data management –exception reporting technique to transfer wireless data that ensures the most reliable, secure and fastest transfer physically possible. This technique also provides easy scalability and increased bandwidth.
• Frequency Hopping Spread Spectrum (FHSS) –random use of a defined band of frequencies. Invented during the WWII as a way to send wireless data more securely with less interference.
• AES (Advance Encryption Standard ), WEP (Wired Equivalency Privacy ) –these are encryption techniques used in today’s wireless world.

Things to take away• Cost-effectiveness - When directly compared to wired installations, wireless is a very cost
effective alternative. Wireless modules allow seamless integration into all applications enabling installation costs to be kept to a minimum.
• Reliability - Radio protocols include multiple addressing levels, error checking, handshaking and automatic re-try mechanisms that guard against transmission failure. Should a communications failure occur, wireless solutions can provide multiple levels of alarm.
• Security - Most technology employed is state-of-art. As a result, each product has four levels of protection.
– Data is embedded in wireless transmissions using a unique modulation technique. – The data format has a unique structure with added security features, including network
and address validation. – Data is encrypted using a high-security encryption algorithm. – Wireless protocol operates on an exception-reporting basis, transmitting when there is a
change. This greatly increases the difficulty in collecting wireless samples for decoding.
• Ease of installation - Our modules have built-in diagnostics and remote configuration abilities that are designed to save time and hassles. Our free 24 hour technical support provides further assistance should you require it.
