RockBLOCK Logger | Satellite-Enabled Data Logger

RockBLOCK Logger is a micro datalogger built for remote sensor capture in harsh, off‑grid environments. Housed in a rugged IP68 shell, it offers two dry‑contact digital inputs, one configurable 0–10 V/4–20 mA analog channel, and both BLE‑ and Cloudloop‑based configuration.

It runs directly from 8–32 V DC (solar‑ or battery‑backed) and sips as little as 380 mW at hourly reporting intervals, perfect for long term environmental monitoring where every milliwatt counts.

RockBLOCK Logger brings global satellite reach to applications like water level logging, soil moisture sensing, or industrial telemetry – no site visits required and seamless data flow via Ground Control’s Cloudloop platform.

A lightweight alternative to traditional RTUs, RockBLOCK Logger is ideal for remote sites where power, space, and connectivity are at a premium.

Providing real‑time visibility of existing telemetry readings, Cloudloop Data Insights provides a straightforward means of anomaly detection and continuous monitoring of your sensor data streams. Setting up your threshold alerts means your team can be informed immediately if a sensor reading deviates from expected norms (e.g., temperature spikes, moisture drops, flooding, quality levels).

Capturing, logging and archiving time‑series data from sensors enables users to review historical patterns, perform trend analysis, and identify recurring issues (e.g. seasonal environmental shifts or repeating sensor failures). The platform provides the insight and continued record for legislative and auditing purposes.

Sensor readings from diverse device families are ingested in a consistent format, making it easy to compare and analyze data across different sensor types and locations.

For developers wishing to assimilate the information into their own system, we offer pre-integrated data destinations to ease integration and data analysis.

FAQs About RockBLOCK Logger

Which sensors are compatible with RockBLOCK Logger?

RockBLOCK Logger accepts any industry‑standard 4–20 mA transmitter plus two dry‑contact digital inputs. Popular 4–20 mA sensors include:

Level sensors (e.g. Gems LS‑7, VEGA VEGAPULS series)
Pressure transducers (e.g. Rosemount 3051, WIKA A‑10)
Temperature transmitters (e.g. Endress+Hauser iTEMP TMT82, Omega TXDIN series)
Flow meters with 4–20 mA outputs (e.g. Krohne Optiflux, Proline Promag)
pH/ORP probes paired with 4–20 mA converters (e.g. Consort C532)
Humidity/temperature transmitters (e.g. Vaisala HMP60, Honeywell HIH series)

Plus any other sensor that provides a 4–20 mA loop signal or simple dry‑contact status. Plus, we have extensive experience of integrating industry-specific protocols including MODBUS and DNP3, so please get in touch if you have a specific protocol and want to check compatibility.

I need my sensor data in real-time; what would you recommend?

For real time, low latency reporting, choose the Iridium SBD version of RockBLOCK Logger. SBD delivers true, near‑instant Short Burst Data over the global Iridium constellation, ensuring each measurement is pushed immediately to the cloud – ideal for time‑critical alerts or continuous monitoring. By contrast, the NTN NB‑IoT variant trades immediacy for ultra‑low power, batching data at scheduled intervals. If “always‑on” visibility is your priority, the SBD model is the clear choice.
