What is the wireless pressure sensor ?
Wireless pressure sensor also called wireless pressure transmitter. Wireless pressure sensor acts as a battery-powered pressure measurement monitoring system with the function of measuring the gauge pressure of gases and liquids in a piping.
what would be the wireless pressure sensor principle ?
China SenTec manufacturered wireless pressure transmitter adopts high-precision and high-stability diffused silicon as pressure-sensitive chip, advanced technology, support point-to-point, point-to-multipoint, serial-to-serial applications, and transmit data through wireless(Lora, LoraWan, 4G, Nb-Iot etc.) network, and integrate all the monitoring data in one software or platform.
what is the different among the different wireless signals, like Lora, Lorawan, 4G, Nb-Iot etc. ?
To simplify, there are 2 types signal monitoring format. One type is what we will use the wireless pressure transmitters and receivers (gateway) to read the data, usually by computer monitoring software to read all details, such as the Lora and LoraWan. Another type is the upload the monitoring to the cloud by SIM card to read data directly on phone or computer, rather than go through the gateway, this case we mostly see is 4G, Nb-Iot signal type.
How does SenTec wireless Lora pressure sensor/transmitter works ?
Let’s get a overview of SenTec Lora pressure sensor. SenTec Lora sensor manufacturer module based on Germany SEMTECH RF integrated chip with Low Power LAN wireless standard. The name of LoRa is Long Range Radio. Its biggest feature is that it can travel farther than other wireless methods under the same power consumption conditions, realizing the unity of low power consumption and long distance. It consumes 3-5 times longer than the traditional wireless radio communication distance.The LoRa modulation technology is adopted to realize on-site distributed multi-point IOT equipment monitoring and collection. The communication distance can reach 2km, and data from sensors, PLCs, smart meters, etc. can be passed through radio frequency.LoRa radio frequency is mainly used for multi-point and long-distance distributed sensor acquisition and transparent transmission of RS485 serial devices, instruments, and transmitters to the cloud platform.
What is the Lora pressure sensor advantages and disadvantages?
Advantages:
- Lora sensor battery is designed with 38000mAh large battery capacity, battery life estimated 3~4 years (eg. data update interval 1 hour)
- Lora sensor range up to 100Mpa, support other custom ranges
- Measuring accuracy reach up to 0.1%
- Lora sensor data transmission frequency: ISM frequency bands include 433Mhz (default), 868Mhz, 915Mhz, etc.
- Lora sensor manufacturer: 12 years warranty
- Lora sensor module: using semtech chips imported from Germany
- Lora sensor price: most effect price price
- Adopts LoRa digital spread spectrum, digital signal processing and error correction coding technology
- Low power consumption design: low transmission distance and strong anti-interference ability
- High sensitivity and reliable connection: spectrum modulation technology to demodulate less than 20 db of noise
- Transmission distance: The open distance can reach 2-5 Km, default distance design is 1KM.
- Capacity: A LoRa gateway can connect thousands of LoRa nodes.
Disadvantages:
- Requires regular battery replacement
- The cost is a little bit higher compared with standard cable wired pressure sensor/transmitter
Now, SenTec manufactured Lora/4G wireless pressure sensor are globally installed more than 30,500pcs and well recognized by their stable and perfect performance.
