Temperature Probe Sensor


The Wireless Temperature Probe Sensor measures Temperature (°C/°F) through an industry-standard PT100 or PT1000 temperature probe. The sensor comes with a 4-pin connector that supports and automatically detects probes with 2, 3, and 4-wire configurations. The measurements are wirelessly transmitted to nearby Cloud Connectors (gateways) at a predetermined Heartbeat Interval (HBI) via the SecureDataShot™ protocol. Cloud Connectors relay sensor data to the cloud via cellular or ethernet connectivity. From the cloud, the data can be integrated into other services using REST APIs and webhooks or viewed directly in DT Studio.

The Wireless Temperature Probe Sensor uses HBI to transmit a message notifying the system that it is present and operational, which can be set to 2.5 min, 5 min, 15 min, 30 min, 45 min, or 60 min.

This sensor comes in two versions: EU (Product No. 102772) and US (Product No. 102774), each tailored to meet distinct regional certifications, compliances, and wireless communication requirements.

Temperature Probe PT100 is not included by default and can be ordered separately.
