BEAM-TM-L
Choose the right tiltmeter for your deployment
BEAM-TM vs BEAM-TM-L
Both sensors support reliable tilt monitoring, but they are designed for different deployment conditions. As Ackcio phases out the legacy BEAM-TM, the BEAM-TM-L is the recommended choice for new open-air and point-to-point deployments.
Recommended for new deployments: BEAM-TM-L
Its wider measurement range, triaxial sensing, event-triggered acquisition, LoRaWAN connectivity, and multi-year battery life make it the practical starting point for most new projects.
| Key difference | BEAM-TM Mesh tiltmeter · specialist fit | BEAM-TM-L LoRa tiltmeter · recommended for new projects |
|---|---|---|
| Best fit | Complex or obstructed sites where a self-healing mesh helps relay data across the deployment. | Open-air, point-to-point deployments with clear line of sight to a gateway. |
| Wireless architecture | Ackcio Mesh with up to 50 nodes and up to 12 hops. | LoRaWAN single-hop connectivity; integrates with LoRaWAN networks and third-party servers. |
| Measurement range | ±15° | ±90° |
| Resolution | 0.0001° | 0.001° |
| Axes and acceleration | Biaxial tilt measurement; no acceleration sensing. | Triaxial tilt measurement plus ±2g acceleration sensing. |
| Real-time event alerts | Scheduled transmission only. | Tilt and acceleration triggers can wake the device, record an event, and report it immediately. |
| Battery life | Approximately 6–18 months, depending on sampling interval and deployment conditions. | Multi-year battery life; the current datasheet estimates more than two years in dynamic alarm mode and up to five years in normal scheduled operation, depending on interval and conditions. |
| Operating temperature | −40°C to +80°C | −20°C to +70°C |
| Primary trade-off | Choose for mesh resilience and complex, obstructed environments. | Choose for broader tilt coverage, event detection, and lower maintenance. Each node needs a clear path to the gateway. |
Why BEAM-TM-L is the direction for new projects
- Measures tilt across a full ±90° range.
- Adds acceleration sensing and trigger-based monitoring.
- Supports open LoRaWAN deployments.
- Reduces maintenance visits with multi-year battery estimates.
When BEAM-TM may still fit
Existing or highly obstructed deployments may still benefit from Ackcio Mesh, especially where nodes must relay data through one another or where clear line of sight to a gateway is difficult.
