Heating Element Calculations & Ohm’s Law

admin — Mon, 20 Jun 2011 16:38:40 +0000

Heating Element Calculations

In order to make the basic calculations for the design of heating elements the following formulas, known as Ohm’s Law, are essential:

Volts = Amperes x Ohms Calculator

Watts = Volts x Amperes Calculator

Watts = (Amperes) 2 x Ohms Calculator

Useful Coil Formulas

Length of one turn of wire = π (Outside coil dia. - wire dia.) Calculator

Number of turns of wire per inch of coil = 1 / Wire Dia. Calculator

Length of wire in 1″ of closed coil = π(Outside coil dia. - Wire dia.) / Wire dia. Calculator Calculator

Resistance per inch of closed coil = π(Outside coil dia. - Wire dia.) (resistance / ft. of wire) / 12 (Wire dia.) Calculator

Length of coil = Total resistance of coil / Resistance per inch of closed coil Calculator

Combining the above formulas given above we get the complete formula for coil calculations.

Length of Coil = Coil Resistance x Wire Dia. / .262 (Coil Outside Dia. - Wire Dia.) (Resistance / FT. of Wire Used) Calculator

Wire Resistance = (Ohms / Cir. Mil. Ft.) / Diameter² (expressed in mils.) Calculator

Strip & Ribbon Resistance = (Ohms / Sq. Mil. Ft.) / Thickness (Mils.) x Width (Mils.) x Correction Factor Calculator

Wire Wt. = πr² x Length x Lbs./Cubic Inch Calculator

Strip Wt. = Thickness x Width x Length x Lbs./Cubic Inch Calculator

Ohms/Sq. Mil. Ft. = Ohms/Cir. Mil. Ft. x .7854 Calculator

Pelican Wire Co. discusses social responsibility and it’s commitment to sustainability in Wire Journal International, Page 68.

Social responsibility is a big factor in a lot of our opera- tional decisions. We also get peer pressure from our “greener” customers, such as one that made a die to remold their PEX bleed out scrap into packaging materi- als for their product. Reduction of VOCs in our saturation and enameling processes has been our most conscious decision in this regard.
The solvent-based prod- ucts have more history and are easier to work with (shorter drying times, better adhesion, etc.) but they are not very environmentally friendly. We spend a lot of time finding water-based sub- stitutes and adapting them to our products whenever possible.

Often times “green” may refer to RoHS and REACH compliance. Since the advent of RoHS, the Union Court has new rulings, such as the list of hazardous substances changes. For instance, Deca-BDE (decabromodiphenylether) was recently put back on the list. There are still a number of companies who purchase and use this FR component in their product (knowingly). We, however, do not. Brad Burris, Pelican Wire Company, Inc.

What types of thermocouple wire do you carry?

admin — Mon, 20 Jun 2011 13:30:57 +0000

We stock bare and insulated thermocouple wire in ANSI Type J, K, T, and E calibrations with traceability to NIST. We supply thermocouple wire as small as 40 AWG. Insulated thermocouple wire can be custom built to the customers’ exact specifications including calibration type, wire gauge, and individual calibration requirements. We supply bulk insulated thermocouple wire to many instrumentation manufacturers for use in their products. We also make insulated thermocouple wire for use from -400°F to over 2,200°F. Learn more on our thermocouple wire page.
