- High-quality compact integrated weather station
- No moving parts
- Accurate and rugged solid state sensors
- Measures wind speed and direction, temperature, humidity, pressure and solar radiation
- Multiple additional derived parameters
- Built in electronic 2-axis compass
- SDI-12 enabled
The high performance GMX501 compact weather station is simple to install, use and maintain.
In addition to providing 6 measured parameters – the GMX501 can derive multiple additional parameters based on combining measured parameters, such as gust, average wind speed and dew point.
A neat, powerful and flexible weather monitoring solution
The GMX501 is engineered to ensure high measurement accuracy, low maintenance, and reliable continuous status reporting. It includes a range of sensor configurations allowing customers to select the model most appropriate to their needs.
The GMX501’s data is output as a single string which is available on a range of communications protocols – SDI-12 is default, but can be switched by user to MODBUS, RS232, RS422, RS485 or NMEA*.
Key benefits
- High quality measurement data due to careful sensor selection and extensive design testing and verification.
- Easy to set-up and integrate using comprehensive software to select the reported and derived parameters and measurement units required.
- Easy to install and long operational life, due to a compact, robust design and the selection of low maintenance sensors.
- Suitable for use with battery or solar systems in low power mode.
Typical applications
- Control systems including agriculture, smart buildings, and industry.
- Solar farms.
- Road and rail.
- Ports and harbours.
- Reporting systems for transport and safety.
- Low power/solar powered deployments and IoT applications.

FAQs
- Setting up an M12 cable network to ensure a waterproof and secure connection.
Question
What is the best practice for setting up a M12 cable network to ensure a waterproof and secure connection..
Answer
It applies to:
GP2 for SDI-12 and logger networks.
Celora for SDI-12 networks.
All sensors with M12 connector cables.Examples of SDI-12 network and GP2 logger networks:
DO
When connecting multiple cables and T-piece together, it is essential that any M12 connector is tightened sufficiently:• Ensure internal connector O-ring and opposite sealing face are free from dirt.• Tighten the connector thumbscrews as much as you can by hand or use a torque driver set to 1Nm to be sure. See video:
We recommend the Weidmuller ‚”1900021000″ torque driver:
• This will save lots of painstaking troubleshooting hours if you do have a loose connection and give you piece of mind that all connectors are correctly tightened.
• Untightened connectors can come undone and let water into the cable network which can damage wire cores and cause erroneous readings.
Connect in the office first and then transfer the network to the field. This way, you’re not trying to do it in unpleasant weather and the time pressures are off.
DON’T
Use duct tape. This will hold water against the connector. If tightened correctly, the connector will seal and hold.
