Tis' the season for business and corporate gift-giving! If you believe in the law of reciprocity, and if your business is the least bit successful you must; you know that giving back is not only the right thing to do, but it's very smart business as well. Let's look at some of the benefits and mechanics of Christmas and holiday gift-giving.* WHY DO IT AT ALL?Gift giving is an excellent way to not only say thank you for all the business and continued loyalty your clients and customers have shown over the past year, it help to solidify relationships and in some cases, actually tilt the playing field in your favor.

Measurement and control of temperature is one of the most common requirements of industrial instrumentation and the thermocouple is by far the most widely used temperature sensor. Its characteristics include good inherent accuracy, suitability over a broad temperature range, fast thermal response, ruggedness, high reliability and low cost.
How does a thermocouple work?
T.J Seebeck discovered in the 1820s that an electric current flows in a closed circuit of two dissimilar metals when one of the two junctions is heated with respect to the other. In a thermocouple circuit the current continues to flow as long as the two junctions are at different temperatures. The magnitude and direction of the current depends on the temperature difference between the junctions and the properties of the metals used in the circuit. This is known as the Seebeck effect. Click here to see an example of the circuit.
If the circuit is broken at the center, the net open circuit voltage (the Seebeck voltage) is a function of the junction temperature and the composition of the two metals.
If the hot and cold junctions are reversed, current will flow in the opposite direction. Any two dissimilar metals can be used and the thermocouple circuit will generate a low voltage output that is almost (but not exactly) proportional to the temperature difference between the hot junction and the cold junction. The voltage output is between 15 and 40µV per degree C, dependant on the thermocouple conductor metals used. The actual metals used in industrial thermocouples depend on the application and temperature measurement range required.

If you use direct marketing and sales letters you know they are the unpaid, untiring salesmen for your product. Make them effective and they will reward you. If they are ineffective you are leaving so much money on the table. Try the following tips to make the most of your salesmen-in-print.Tip One - Analyze other people's sales letters. If you receive a sales letter and you are tempted to buy file it away. When you next have to write a sales letter get the file out and look for inspiration. For each retained sales letter examine the wording, the layout, the offer and how it is presented. You can even make notes

If buying a car is one of the most important investments for you, so should be the investment in procuring an appropriate auto insurance for your valuable vehicle. Most people carelessly hook up any car insurance agent, who works more for his benefit rather than yours, keeping you completely neglected of the benefits that an appropriate and affordable car insurance can accrue to you.The matter is as simple as this: You cannot drive a car in UK if you do not have a motor insurance. It is a law. A big penalty can be levied against you in case you are caught driving a car without insurance cover. Insurance protects both your car

For communication to take place, a message must be transmitted by a communicator and correctly received by a listener. If the message is not understood, there is no communication. There is only noise. Between the transmission and reception of a message, much can go wrong. Communication, by definition, involves at least two individuals, the sender and the receiver. There are certain filters or barriers which determine whether or not the message is actually transmitted or received.There may be barriers that exist between the sender and the receiver such as cultural differences. Environmental conditions may also create barriers,
Thermocouple failure prediction
Like any other metal object, thermocouples are subject to metal fatigue wear and tear; they have a finite life. Many users of thermocouples are not aware of thermocouple deterioration until the sensor breaks, often causing an expensive interruption of a process. Removing a thermocouple from a furnace when at operating temperature can be difficult and dangerous. In fact the thermocouple, a simple and generally inexpensive sensor, can cause inaccurate readings for some time before any errors are detected. The errors usually cause low readings due to the thermocouple wires becoming thinner.
Impurities induced by any handling during manufacture or installation can accelerate chemical deterioration of the thermocouple. For base metal thermocouples, deterioration occurs slowly due to contact with the atmosphere, which in turn causes oxidation. As the surface of the thermocouple wires oxidises the current carrying cross sectional area is reduced. Nobel metal thermocouple deterioration is also well documented.
In "Principals and Method of Temperature Measurement", Thomas D McGee explains that the usual result of deterioration is the gradual reduction in the Seebeck voltage, often extended over several weeks and not frequently detected. If the Seebeck voltage is low, the measured temperature will also be low, so the actual process temperature will be increased to produce the required Seebeck voltage. The net result will be excessive temperature generation with resulting damage to material and processes. Those who use thermocouples should be aware of the possibilities of slow deterioration and its consequences.
