In the production and life of modern society, people are often exposed to various gases and need to be detected and controlled, such as the detection and control of gas components in chemical production; detection and alarm of coal mine gas concentration; environmental pollution Situation monitoring; gas leakage: fire alarm; combustion detection and control, etc. […]

The burners can be divided into universal burners, mass-production burners, and special burners in terms of function. The special-purpose burner has the lowest price and has fewer types of applicable chips. It is suitable for programming with a certain type or type of special chip, for example, it only needs to program the PIC series. […]

Chemical power sources can be divided into three types: primary batteries, secondary batteries (also known as batteries) and fuel cells. As the name implies, a primary battery is a battery that is discarded after one use. For example, zinc-manganese dry batteries, zinc-silver button batteries, etc. contents 1. What is zinc manganese dry battery 2. Reaction […]

1. What is a lead-acid battery The most obvious feature of lead-acid batteries is the unscrewed plastic sealing cover on the top and the vent hole on the top. These filling caps are used for filling pure water, checking electrolyte and exhaust gas. Theoretically speaking, lead-acid batteries need to check the density and liquid level […]

The power supply of the temperature transmitter must not have spikes, otherwise the transmitter may be easily damaged. The calibration of the transmitter should be carried out 5 minutes after power-on, and pay attention to the ambient temperature at the time. When measuring high temperature (>>100℃), the sensor cavity and the junction box should be […]

1. What is the sound and light control delay switch Acousto-optic control refers to an electronic control method that uses sound and light changes to control circuits to achieve specific functions. The acousto-optic control time-delay energy-saving lamp circuit includes sound control, light control sensing elements, amplifiers and a monostable circuit composed of 555 and a […]

Dry-type isolation transformers are widely used in Circuits with AC 50Hz to 60Hz and voltages below 660V, the product’s various inputs, output voltage levels, connection groups, the number and position of adjustment taps (generally ±5%), and winding capacity The distribution of the secondary single-phase winding, the use of the rectifier Circuit, whether it is required […]

1. What is the float level controller The float level controller is composed of float, plunger and so on. Installed on the top of the container through the connecting flange, the floating ball floats on the liquid surface according to the principle of discharging liquid volume phase and so on. When the liquid level of […]

The sound and light alarm is a kind of sound and light alarm equipment installed on the scene. When a fire occurs and is confirmed at the scene, the fire sound and light alarm installed on the scene can be activated by the fire alarm controller controlled by the fire control to send out a […]

Electronic connectors (also often called Circuit connectors, electrical connectors) are conductor devices that bridge two conductors on a loop so that current or signals can flow from one conductor to another. An electronic connector is a motor system that can provide a separable interface to connect two secondary electronic systems. Simply put, the components used […]
