Things in the world is a perception of the world, including the perception layer, transport layer, the platform layer and application layer. As the saying goes, a good beginning is half the battle, but the perception of things as a "vanguard", naturally do not question its role, particularly in intelligence, things today, giving objects transmitter "life."
In the networking industry, we often likened to the transmitter of human facial features, but it is not responsible for beautiful flower, which is responsible for perception.
What is a sensor? Use it for?
First, the sensor is a what? Detecting means is a sensor that can sense information is measured, and can feel the information according to certain rules converted into electrical or other forms of information output required to meet the information transmission, processing, storage, display , recording and control requirements. Its characteristics are miniaturized, digital, intelligent, multi-functional, systematic, network.
You first need a clear distinction between sensor and transmitter. It is now said that the sensor is composed of two parts, namely the conversion element and the sensitive element. Wherein the sensor means sensitive element directly feel or response part is measured; refers to the conversion element is converted in the sensor response or feel sensitive element suitable for transmission measurements into electrical signals or measurement portion.
Transmitter diversity type used in industrial instrumentation above the main transmitter temperature transmitters, pressure transmitters, flow transmitters, transmitter current, voltage transmitter and the like. Corresponds to a signal transmitter amplifier. Typically, the transmitter power is provided to the sensor, and the amplified signal.
Today to introduce a wireless pressure transmitters, wireless pressure transmitter is a battery-powered digital pressure gauge wireless low-power / wireless digital output terminal, also known as intelligent wireless pressure.
Pressure transmitter optional wireless GPRS, LORa-iot, NB- iot wireless protocols. Built-in laser welding type pressure sensor, the pressure can be accurately displayed in real time and with high precision, good long-term stability.
Equipped with a large-sized liquid crystal display LCD, a built-MCU, low-power design, to achieve the line pressure field is uploaded to the cloud wireless transmission.
304 linker and the whole cast aluminum housing, shock resistance, capable of measuring gas, liquid, oil of stainless steel non-corrosive media.
Wireless pressure transmitter Technical features:
☆ the GPRS / LORaWAN / NB-The IOT of transmission
☆ TCP / UDP / MQTT / Coap multiple protocols
Times given message + ☆ combination of event messages, ensure timely warning
☆ remote parameters (hair frequency, the frequency acquisition, alarm, etc.)
☆ four LCD screen, the backlight white
hair ☆ interval, adjustable keys, one minutes to 24 hours provided
☆ low-power design, 3.6V battery, the hair can support more than 12,000 times
application: fire water supply network, the end of the fire, fire pump, city water, petrochemical and other needs unattended, remote monitoring of the field.
Things in the world is a perception of the world, including the perception layer, transport layer, the platform layer and application layer, particularly in intelligence, things today, giving objects transmitter "life." Smart City, wisdom, health, wisdom security, the wisdom of agriculture, water conservancy ...... wisdom these all need to energize the pressure transmitter can be achieved.
