LoRaWAN Current Input Sensor
SKU: WSLRW-MA
WSLRW-MA is the LoRaWAN wireless sensor with one channel to measure 0-20mA DC current from Process instruments like Pressure transmitter, Temperature transmitter, Level transmitter, Flow meters, Analyzers... at very low voltage drop. With Ultra-low-power design and smart firmware allow the sensor can last up to 10 years with 2 x AA batteries (depends on configuration). The sensor will transmit data in the kilo-meters distance to LoRaWAN gateway, any brand on the market.
LoRaWAN communication
- LoRaWAN communication standard to allow sensor connect to any LoRaWAN Gateway on the market.
10 year battery
- Ultra-low power sensing technology from Daviteq with Ultra-low power wireless technology allow the sensor can last up to 10 years with a 2 x AA Type battery.
Pre-calibrated
- Sensors are pre-calibrated at factory to deliver high accuracy and quick installation
IP68
- For both indoor and outdoor applications
