IoT Wireless Temperature Sensor for 4 external Pt1000 probes with ELKA connector, LoRaWAN network

The W0941 sensor with LoRaWAN network output measures temperature from four external Pt1000 probes on the cable and can be installed directly in the measured environment thanks to its IP65-rated enclosure. LoRa devices are powered by a replaceable battery with a lifespan of up to 10 years (3 years standard). External power with optional accessories is also available.

Measured values are transmitted wirelessly at adjustable intervals (from 5 minutes to 24 hours) to the COMET Cloud storage, where they are accessible to users via computer or mobile device. The sensors offer remote configuration from the COMET Cloud and feature the capability to monitor up to two alarm thresholds, with any exceedance signaled by an alert sent to the user.

Key Features

Wireless transmission of measured values and alarm states
Battery-powered with low battery indicator (battery life up to 10 years) and external power option
Remote device configuration via COMET Cloud
IP65-rated enclosure
Calibration certificate with declared metrological traceability of standards according to CSN EN ISO/IEC 17025
Preconfigured Gateway available as an accessory at extra cost. For easy use, we offer several types of preconfigured LoRaWAN gateways that are fully prepared for communication with COMET Cloud and our sensors. This option simplifies the setup process and saves time for users
