Help & Support
Get the most out of CONTEMP with expert guides and troubleshooting tips for seamless concrete temperature and maturity monitoring.
CONTEMP is an advanced concrete temperature recording and maturity monitoring system designed for construction, infrastructure, and concrete curing applications. It consists of two key components:
- CONTEMP Hardware: A 3-channel temperature recorder and alarm system that operates on 4xAA batteries and connects directly to the cellular network without requiring additional gateways. The hardware includes:
- One ambient temperature sensor for environmental monitoring.
- Two external sensors for deeper insight into concrete curing conditions.
- CONTEMP Web Application: A cloud-based platform hosted at app.contemp.live that allows users to monitor, analyze, and generate reports on concrete temperature trends and maturity development.
1. Device Management
- Users can register, search, and configure CONTEMP devices through an intuitive interface.
- The dashboard provides a clear overview of all connected devices, allowing users to access detailed sensor data.
- Customizable Sensor Settings: Users can rename sensors, set temperature thresholds, and define alarm limits to ensure compliance with curing requirements.
2. User Access and Permissions
CONTEMP includes multiple access levels to accommodate different user roles:
- Viewer: Can access temperature and maturity data and receive alerts but cannot modify settings.
- Editor: Has full control over sensor settings, reporting, and device configurations.
- Service & Maintenance Access: Designed for trusted service partners, providing predictive maintenance and specialized monitoring capabilities.
- Silent Viewer (New Feature): Allows designated users to access all monitoring data without receiving notifications, useful for large teams or regulatory bodies.
3. Graphing and Data Visualization
- Users can view and analyze historical temperature data through interactive graphs.
- Data trends can be explored for different time periods, enabling a thorough understanding of temperature fluctuations.
- The interface includes paginated readouts, where users can access complete timestamped sensor records.
- Users can toggle sensors on and off to focus on specific measurements for comparison and analysis.
4. Reporting Features
- Users can generate various structured reports to document temperature and maturity progress.
- Detailed Results Report: Provides a full export of all sensor readings in Excel format.
- Hourly Report: Consolidates readings into hourly intervals for better clarity.
- Min/Max/Average Daily Report: Summarizes daily readings in a simplified format.
- Reports are fully customizable, with the ability to adjust time intervals and export in PDF or Excel format.
5. Data Consolidation
- Users can merge temperature data from multiple CONTEMP devices into a single report.
- The system ensures consistency by selecting readings closest to round-hour timestamps for better comparison.
- Two options for consolidating data:
-
- Closest Existing Reading: Selects the nearest available temperature record from the database.
- Linear Interpolation: Estimates values between two readings to maintain uniform data points.
- This feature is particularly useful for multi-sensor analysis, such as comparing ambient temperature with multiple concrete curing locations.
6. Concrete Maturity Monitoring
The maturity module in CONTEMP calculates concrete strength development based on temperature history and a defined calibration curve.
How it works:
1. Calibration Curve Definition
- The calibration curve represents the relationship between temperature history and concrete strength.
- Users input lab-tested strength data into the system, either manually or by uploading an Excel file.
- The system automatically stores and applies the calibration curve for future projects.
2. Maturity Calculation
-
- CONTEMP continuously monitors concrete temperature and applies maturity equations to estimate strength development.
- We use the Temperature-Time Factor (Nurse-Saul) equation in accordance with ASTM C 1074.
- The system tracks cumulative temperature exposure over time to determine concrete curing progress.
3. Project Tracking Dashboard
-
- Displays ongoing and completed projects, showing:
- Current maturity level based on temperature history.
- Target strength required for project completion.
- Estimated time remaining until full strength is achieved
- Current maturity level based on temperature history.
- Users receive automatic notifications once the concrete reaches its specified strength, ensuring timely decision-making.
- Displays ongoing and completed projects, showing:
4. Comprehensive Maturity Reports
-
- Users can generate reports that include:
- Daily strength development progress.
- Temperature readings from all sensors involved in the project.
- The applied calibration curve and corresponding calculations.
- Users can generate reports that include:
-
- Reports are available in PDF and Excel formats and include any images or project notes added by the use
7. Edit & Ownership Transfer
- Users can modify device and sensor settings at any time to match project requirements.
- Ownership Transfer (New Feature):
- If a device is already registered to another account, a transfer request is sent to the current owner.
- Owners can approve access or transfer ownership directly through the platform.
- QR Code-Based Registration simplifies the activation process, eliminating the need for manual serial number entry.
8. Activity Logs & Security
- Activity logs maintain a complete history of user actions, including:
- Login and logout records.
- Alarm setting adjustments.
- Report generation and data modifications.
- Logs are permanently stored and can be downloaded as a tamper-proof PDF, ensuring full compliance with project documentation requirements.
Conclusion
CONTEMP is a powerful solution for concrete temperature and maturity monitoring, conforms to ASTM C1074 and provides detailed insights into your pour. By combining advanced temperature measurement, calibration curve-based strength estimation, and automated reporting, CONTEMP supports you in making data-driven decisions (mitigating temperature differential) and reliably delivering data.
