NB IoT wireless pressure transmitter Introduction:
Wireless sensor is a wireless pressure, liquid level, temperature and pressure integrated instrument equipped with NB IoT module.
Compatible with diffused silicon sensors and PT100 temperature sensors. It is an ideal low-power instrument for pressure, temperature acquisition, transmission, and display. Suitable for smart city application scenarios such as oil fields, water conservancy, pipeline networks, water supply pipelines, and urban heating pipelines. characteristic:
1. Sample low-power microprocessor, NB IoT wireless communication, battery powered, low-power operation, battery life of 2-5 years (affected by upload interval time).
2. No need for gateway routing RTU or other devices, data is directly connected to the backend server, and installation is simple;
3. A complete and rigorous backend protocol, providing a concise API interface, can easily access historical data through web, PC, Android APP and other applications, and save operational data within one year.
4. Support data access services for third-party platforms, suitable for oil fields, tap water, mines, and water conservancy. Parameter settings are suitable for use by group users.
5. Strong anti-interference characteristics, good temperature characteristics of the whole machine, working temperature range of -30-70 degrees.
6. Can be used as a standalone wireless transmitter for temperature, pressure, and temperature pressure integration. Built in alarm settings and panel alarm lights.
7. Curve fitting calibrates temperature and pressure curves, presenting pressure and temperature characteristics with high stability.
8. IP65 or above high protection level, suitable for outdoor occasions.
9. User on-site button calibration function. Support users to calibrate the transmitter twice.
