1. What is an audio delay “Audio Delayer” (hereinafter referred to as “delayer”), as its name implies, is an audio device that delays sound signals. In the traditional concept of use, it is still simple to delay the sound signal during long-distance sound reinforcement. In fact, the function of the delayer is not limited to […]
1. What is the delay switch The time delay switch is a new type of automatic time delay Electronic switch developed to save power resources, which saves electricity and is convenient. Mainly used in stairwells, toilets and other places. The delay switches include touch delay switches, sound and light control delay switches, etc. As long […]
1. What does admittance mean Admittance is the amount of energy released by the system when the voltage changes. Admittance is used to describe the difficulty of alternating current passing through a Circuit or system. Use an imaginary number to express susceptance, and the unit is Siemens. Its value is equal to the ratio of […]
At present, the motor protector has been developed from the mechanical type to the Electronic type and intelligent type, with high sensitivity, high reliability, multiple functions and convenient debugging. It can directly display the current, voltage, temperature and other parameters of the motor. After the protection is activated, the type of fault is clear at […]
1. The principle of temperature and humidity transmitter The temperature current transmitter converts the signal of the temperature sensor into a current signal, and then connects it to the secondary instrument, so that the corresponding temperature can be displayed. For example, the model of the temperature sensor in the picture is PT100, then the function […]
The abbreviation of TD-CDMA mobile communication standard TD-SCDMA (one of the 3G standards) TD is the TD-SCDMA independently developed by our country. TD-SCDMA is a technical standard proposed by our country with independent intellectual copyright. Its Chinese meaning is Time Division Synchronous Code Division Multiple Access, which is a technical standard of wireless communication. It […]
In computer networks, the “this generation” network is the Internet based on IPv4, and the next generation network is NGI (Next Generation Internet) based on high bandwidth and IPv6. In the transmission network, the “this generation” network is based on TDM, represented by SDH and WDM, and the next generation network is based on ASON […]
1. What is a transmitter The transmitter (transmitter) is an important part of the automatic control system. It plays a pivotal role in the field of instrumentation and industrial automation. The transmitter measures temperature, pressure, liquid level, composition and other physical quantities and converts them into a unified In addition to the standard signal, it […]
The tension controller is a system developed by a single-chip microcomputer or some embedded devices and peripheral Circuits. It is a control instrument. It can directly set the tension value required to be controlled, and then directly input the signal of the tension sensor (usually millimetres). Volt level) is used as the tension feedback value. […]
1. What is a ceramic capacitor Ceramic chip capacitor is a kind of capacitor made of ceramic material as a medium, coated with a metal film on the ceramic surface, and then used as an electrode after high temperature sintering. It is also called a ceramic disc capacitor. They are high-voltage ceramic capacitors and low-voltage […]
