pantron electrical components Germany pantron model pantron price

pantron electrical components are indispensable measuring instruments for departments such as power electronics, generally with the main purpose of measuring voltage, current, and resistance. Multimeters are divided into pointer multimeters and digital multimeters according to the display method. It is a multi-function, multi-range measuring instrument. General multimeters can measure DC current, DC voltage, AC current, AC voltage, resistance, and audio levels, etc. Some can also measure AC current, capacitance, inductance, and some semiconductor parameters (such as β). A multimeter is a magnetoelectric instrument with a rectifier that can measure various electrical parameters such as AC/DC current, voltage, and resistance. For each electrical quantity, there are generally several ranges. Also known as a multi-meter or simply multi-meter. A multimeter consists of a magnetoelectric ammeter (meter head), measuring circuit, and selector switch. Through the switching of the selector switch, various electrical parameters can be measured conveniently. The main basis for its circuit calculation is Ohm's law for closed circuits. There are many types of multimeters, which should be selected according to different requirements during use.

The main characteristics of thermistors are: (1) high sensitivity, with a resistance temperature coefficient larger than that of metals; (2) wide operating temperature range; (3) small size, capable of measuring temperatures in gaps, cavities, and blood vessels within living organisms that other thermometers cannot measure; (4) easy to use; (5) easy to process into complex shapes and suitable for mass production; (6) good stability and strong overload capacity.

pantron electrical component functions

The modulation pulses generated by the oscillation circuit pass through the reflection circuit, and light pulses are radiated by the light-emitting tube GL. When the object under test enters the effective range of the light receiver, the reflected light pulses enter the phototransistor DU. In the receiving circuit, the light pulses are demodulated into electrical pulse signals, then amplified and synchronously gated and shaped by an amplifier, and then interference is eliminated using digital integration or RC integration methods. Finally, the photoelectric switch control signal is output by triggering the driver after a delay (or without delay). Photoelectric switches generally have good hysteresis characteristics, so even if the detected object shakes within a small range, it will not affect the output status of the driver, thereby keeping it in a stable working zone. At the same time, the self-diagnosis system can display the light-receiving status and stable working zone to monitor the work of the photoelectric switch at any time. Proximity switches are widely used in aviation, aerospace technology, and industrial production. They are also applied in daily life, such as in automatic doors in hotels, restaurants, and garages, and in automatic hot air blowers. In terms of security and anti-theft, important places such as archives, finance, banking, museums, and vaults are usually equipped with anti-theft devices composed of various proximity switches. In measurement technology, such as length and position measurement; in control technology, such as displacement, speed, and acceleration measurement and control, a large number of proximity switches are also used.

Mercury switches achieve switching on and off based on the movement of mercury encapsulated in a glass or metal housing. Therefore, compared with mechanical switches, mercury switches have many characteristics: (1) Can be used in harsh environmental conditions. Since the mercury switch is sealed, the internal mercury is isolated from the outside, so it can be used in environments with oil, steam, dust, and corrosive gases. (2) Small external force required for switching. Mercury is the only metal that remains liquid at room temperature. It has high surface tension and specific gravity. As long as a slight external force tilts the mercury switch, the mercury moves to achieve switching. (3) Mercury has good conductivity, and the contact resistance between the electrodes of the mercury switch is generally very small. (4) The current allowed to pass through the mercury switch depends on the electrode material. (5) Since the switching of the mercury switch is determined by the gravity of the mercury, it can work reliably for a long time. (6) The electrode contacts are liquid contacts, with no noise. (7) Since mercury can flow, as long as the acceleration exceeds the set value, the mercury switch can turn on or off, so it can be used as a vibration-sensitive element. (8) Small size, diverse forms, and fully sealed device. (9) Simple structure and low price. (10) High quality, premium products, suitable for beginners
