Schools face many challenges,such as violence,theft and vandalism. Wireless security camera can be used as an indispensable tool to help you protect students, faculty, staff and visitors, and maintain the safety of property and equipment.

With the widespread use of RFID technology, many new products using RFID technology have emerged. RFID wristband is one of them. RFID wristbands are widely used in various industries, and their functions are also different. Now we will introduce the application of RFID wristband.

There are many types of plate heat exchangers, and there are also many types of plate heat exchanger gaskets. Below we introduce the classification of plate heat exchanger gaskets according to different standards. plate heat exchanger gasket is divided into unilateral flow and diagonal flow according to the flow form of heat exchange medium. Correspondingly, plate heat exchanger gasket is divid

There are many applications for an enclosed switching power supply — for example, you can build a 3D printer in which the power supply controls the stepper motor used to position the print head. There are a wide range of types of switching power supplies with different voltages and current ratings to suit a variety of applications, including supplying power to the stepper motors in CNC machines.

A trampoline spring belongs to the technical field of springs, and includes a spring body with two pull hooks at each end, one of which hooks hook the frame, and the other hook hooks a connection ring on the jump fabric, and the hook hooks of the connection ring. The ends of the fins are bent along the circumference in a decreasing diameter.

Automatic Brazing Machine Conveyer chain is made of stainless steel with double roll chains, which adjusts speed with Transducer, move steadily and convenience for adjusting speed.

The input and output power characteristics of the RF amplifier are the main characteristics, because increasing the signal strength is the main purpose of the amplifier. The maximum and nominal range of input and output power will be specified for the RF power amplifier based on specific conditions.

Laser Equipment Winter Maintenance Tips In the winter, the temperature is declining. At this time, we should not only warming ourselves, but also do freeze protection for laser machines to ensure the lifetime of the equipment and reduce the risk cost.

The amphibious excavator is a multi-purpose excavator suitable for land, marsh soft ground and shallow water operating environment. It is widely and efficiently used in water conservancy projects, rivers and lakes in urban and rural construction, and wetland marshes and beach resources. Development and environmental improvement excavation operations. It is a very practical excavator.

The switchable privacy film is injected into the liquid crystal polymer (PDLC) in the form of particles in the middle of two transparent conductive films, and is produced by a special process. Using the characteristics of the nonlinear optical system and the polymer material, all the particles are disorderly arranged when not energized. Since the refractive index difference between the liquid crys
