In the IoT industry, we often compare transmitters to the five senses of humans. They are not responsible for being beautiful; they are responsible for sensing.
What is a sensor? What is it used for?
First, what is a sensor? A sensor is a detection device that can perceive the measured information and convert the perceived information, according to certain rules, into electrical signals or other required forms of information output. This meets the requirements for information transmission, processing, storage, display, recording, and control. Its characteristics are miniaturization, digitalization, intelligence, multifunctionality, systematization, and networking.
First, it is essential to clarify the difference between a sensor and a transmitter. Nowadays, people say that a sensor consists of two parts: the sensing element and the conversion element. The sensing element refers to the part of the sensor that directly senses or responds to the measured variable. The conversion element refers to the part of the sensor that converts the measured variable sensed or responded to by the sensing element into an electrical signal suitable for transmission or measurement.
Transmitters come in a variety of types. The transmitters commonly used in industrial control instruments mainly include temperature transmitters, pressure transmitters, flow transmitters, current transmitters, voltage transmitters, and so on. A transmitter functions as a signal amplifier. Generally speaking, a transmitter provides power to the sensor and amplifies the signal.
Today, I'm going to introduce the wireless pressure transmitter. The wireless pressure transmitter is a battery-powered, low-power, wireless digital-output wireless digital pressure gauge, also known as a smart wireless pressure terminal.
The wireless pressure transmitter can be optionally configured with GPRS, LORa-IoT, and NB-IoT wireless communication protocols. It features a built-in laser-welded pressure sensor that provides accurate real-time pressure display, along with high precision and excellent long-term stability.
It comes equipped with a large-size LCD screen, a built-in MCU, and a low-power design, enabling wireless transmission of on-site pipeline pressure data to the cloud.
Constructed with 304 stainless steel connections and a fully die-cast aluminum housing, it offers good vibration resistance. It is suitable for measuring gases, liquids, oils, and other media that are non-corrosive to stainless steel.
Technical Features of Wireless Pressure Transmitter:
☆ GPRS/LoRaWAN/NB-IoT transmission methods
☆ TCP/UDP/MQTT/CoAP multiple protocols
☆ Combination of scheduled reporting and event-driven reporting to ensure timely alarms
☆ Remote parameter configuration (upload frequency, sampling frequency, alarm values, etc.)
☆ Four-digit LCD screen with white backlight
☆ Upload interval adjustable via buttons, configurable from 1 minute to 24 hours
☆ Low-power design, powered by 3.6V lithium battery, supporting over 12,000 upload cycles
Application Fields: Firefighting water pipe networks, fire system terminals, fire pump rooms, urban water supply, petrochemical industries, and other areas requiring unattended operation and remote monitoring.
The world of the Internet of Things (IoT) is a world of perception, mainly comprising the perception layer, transmission layer, platform layer, and application layer. Especially in today’s era of intelligentization and IoT, transmitters give objects "life." Smart cities, smart healthcare, smart security, smart agriculture, smart water conservancy… all these rely on pressure transmitters to be empowered and realized.
