Decentlab DL-PR26 - Industrial LoRaWAN Pressure and Temperature Sensor
Robust Liquid Level & Temperature Monitoring, 0-1 bar, IP67-rated, 10m Cable
The DL-PR26 is an industrial-grade pressure and temperature sensor that enables precise liquid level monitoring in a wide range of applications. The device measures relative pressure between the sensor head and cable end, providing accurate depth measurements up to 10 meters (1 bar). Integrated temperature sensing ensures accuracy through automatic temperature compensation.
Built for harsh environments, the sensor features a weatherproof IP67-rated polycarbonate enclosure and stainless steel AISI 316L sensor head, ensuring durability in outdoor and underwater installations. Real-time data is transmitted via standard LoRaWAN® technology, ensuring seamless integration with any LoRaWAN network infrastructure. With advanced power management, the device operates unattended for up to 11.4 years on standard batteries while maintaining reliable long-range communication.
