Joule
The standard unit of energy in the International System of Units. Energy equal to the work by a force of one newton acting through a distance of one meter.
A junction box, often referred to as a J-box, plays a crucial role in the functionality of high-capacity weighing systems, including truck scales and rail scales. Its primary function is to safeguard and separate the electrical connections associated with load cells, which are the sensors responsible for measuring the weight of the load. Read More…
Junction Forming
The means of forming the electrical contact between the two wires of a thermocouple. Methods include: Type E; soft or silver soldering for low temperature operation. Type J, K, T; Gas Welding; the wires are twisted together through two or three turns, held vertically in a vise and joined by fusion with a gas flame (usually only borax as a flux). Arc Welding: for small or medium diameter wires. Requires no flux. The arc is struck between the twisted tip and a piece of carbon rod. Resistance Welding; for all thermocouples of very small diameter wires. Uses a capacity discharge type welder. Useful for R, S, B, C, W, J, E, T & K.
