Potentiometer is a variable resistor, which is often used to adjust the voltage and current in the circuit. Basically, there are two types of potentiometers: rotary and sliding. They usually have three pins - two are fixed resistance terminals, and the third is a movable contact (also called sliding contact or cursor), which can be moved along the resistance material to change the resistance value. Six pin potentiometer is actually two independent potentiometers integrated in one package, and each potentiometer has its own three pins. This design is usually used in stereo audio equipment, because the two channels need to adjust the volume synchronously. The six pin potentiometer can also be seen in other applications requiring dual channel control. The connection of the six pin potentiometer usually follows

If the factory uses a thermal relay to protect a large motor, the large wire will break, that is, the screw entering and exiting the thermal relay connection Problems, hot spots and failure points are easy to occur. If fuses and thermal relays are not used, comprehensive motor protectors are used. Because the protectors are through the core, the breakpoints of large wires can be reduced, thus reducing hot spots and fault points. In order to ensure the normal operation of the machine, attention must be paid to the control circuit when using the motor protector connection Question. It can replace circuit breakers, contactors, thermal relays, fuses and other low-voltage electrical appliances. The installation steps of the motor protector are as follows: 1.

sensor connection It has always been one of the most frequently asked questions by customers in the procurement process. Many customers don't know about the pressure sensor connection method. In fact, all kinds of sensors connection The methods are basically the same. Pressure sensors generally have two lines, three lines, four lines, and some have five lines. The two-wire system of pressure sensor BCW33LT1 is relatively simple. General customers know the pressure sensor connection One line is connected to the positive pole of the power supply, and the other line is connected to the negative pole of the power supply through the instrument. The three wire system of the pressure sensor is directly connected to the negative pole of the power supply. Based on the two-wire system, it is a little more troublesome than the two-wire system.

Reliability is a very important consideration in business decisions. From the perspective of a quality engineer or reliability engineer, reliability should be defined as follows: "the continuous performance or maximum possibility of zero failure operation under given conditions," or "the maximum possibility that something can normally play its due function under given conditions and within a specific interval." The reliability field includes the evaluation and optimal selection of a variety of established factors, and it is often determined by the interested parties to adopt some standardized or upcoming methods. Some professional terms such as "derating" and "failure efficiency" are often used in the field of reliability. Generally, reliability engineering certified by the American Quality Association
