Senlab A for indoor 4-20MA Sensors (current loop)

 This Senlab A is a smart LoRaWAN™ sensor with a 4-20mA input for a usage with a compatible pressure transmitter, accelerometer, weather sensor and many others from the 4-20mA family.

The ruggedized and IP68 casing alongside strong radio-communication performances mean this Senlab A is well suited for un-interrupted monitoring in harsh environment.

Sensing Labs advanced sensors offer advanced functionalities such as:

-Datalogging (24 points / radio transmissions)

-“over the air” reconfiguration Additional specifications



Typical applications

  • Tank and silo level monitoring
  • 4-20mA sensors optimization

Fairly common in the industry any  4-20mA sensor can be made ‘smart’ thanks to this Senlab. You can either retrofit wired sensors, or add as many points as you need, enhanced with wireless communications.
