Once installed, the intelligent wireless pressure sensors from SENSA.iO are designed to accurately gauge and monitor the pressure of gas and liquid within a specific pipeline on a large-scale production sites. This helps to remotely improve safety and performance and of industrial hazardous environments through live and intelligent technology.
The wetted material of these wireless pressure transmitters has high corrosion resistance making them suitable for all hazardous locations including within zone 1 areas where flammable gas or vapor may be present. This includes petrochemical plants, paint plants, and steel plants, among others.
SENSA.iO wireless pressure sensors use LoRaWAN for remote communication. LoRaWAN has excellent sensitivity reception, good anti-radio interference capability, and has a communication distance of 10km, and even further when in optimum communication conditions.
The modular design and structure of SENSA.iO wireless pressure sensors makes replacing batteries easy as they don’t need to be removed from the pipeline. They can also be installed anywhere in the factory without any cable wiring work. This makes them perfect for quick and easy on-site maintenance.
They can also be intuitively configured and remotely monitored using an Android or iOS smartphone or device with Bluetooth 5.0.
