Front-end camera and optical fiber transmission mode lightning protection scheme (1)

First, equipment layout status 1 main equipment: network dome camera, optical transceiver 2 vice equipment: 12V/24V power adapter each one 3 transmission mode: network to optical fiber 4 power supply mode: take local power 220v

Second, lightning protection method 1 Power supply lightning protection: use 220V power supply lightning protection device 2 signal lightning protection: blank (shorter network cable does not need lightning protection device)

Differential Pressure Sensor

Gamicos, aims to provide customers more options when they want to buy a product to measure object's pressure. Differential Pressure Sensor, also called differential transmitter or differential transducer, is used to measure the difference between two pressures, It can be used to measure the differential pressure of different medium like water, air, oil, gas, etc. The working principle of the differential pressure sensor is that the measured pressure directly acts on the diaphragm of the sensor, so that the diaphragm produces a small displacement proportional to the water pressure, so that the resistance value of the sensor changes, and the electronic circuit is used to detect this change, and convert the output of a standard measurement signal corresponding to the pressure.
