Tunnel Monitoring System
Measurement Technology for Safe and Efficient Tunnel Operation
Safe and energy‑efficient tunnel operation requires precise and reliable measurement data. J.con GmbH provides robust technology designed for the most demanding conditions.
Measurement Technology for Safe and Efficient Tunnel Operation
Safe and energy‑efficient tunnel operation requires precise and reliable measurement data – both during normal operation and in safety‑critical situations such as fire or incident scenarios. Airflow conditions, temperature, humidity and other tunnel‑relevant parameters form the basis for targeted ventilation control, clear condition assessment and well‑founded operational decisions.
The J.con GmbH product portfolio for tunnel applications comprises robust and field‑proven measurement technology designed for demanding operating conditions in road and rail tunnels. The systems capture safety‑relevant parameters accurately, continuously and under real environmental conditions – even in the presence of high humidity, strong temperature fluctuations, exhaust gases or corrosive influences.
With TPA for cross‑sectional airflow measurement and THU for the reliable measurement of temperature, humidity and dew point values in tunnels, J.con offers modular measurement systems that can be seamlessly integrated into existing tunnel control, ventilation and automation infrastructures. Designed for long‑term stability, low maintenance requirements and maximum operational reliability, they support safe, cost‑efficient and future‑proof tunnel operation.

TPA – Ultrasonic Airflow Measurement for Road and Rail Tunnels
Precise determination of air velocity and airflow direction in tunnels.
TPA is a contactless ultrasonic measurement system for the precise determination of air velocity and airflow direction in tunnels. By measuring across the tunnel cross‑section, TPA delivers representative and unambiguous airflow data that can be reliably used both in routine operation and in safety‑critical situations such as fire events.
The system is based on the proven time‑of‑flight measurement principle and operates entirely without mechanically moving components. This design ensures high long‑term measurement stability while keeping maintenance requirements to a minimum. Advanced signal processing and diagnostic functions reliably distinguish valid measurement signals and automatically adapt the evaluation to the specific installation conditions.
The fully encapsulated ultrasonic transducers are engineered for continuous operation in harsh tunnel environments. Even under high humidity, significant temperature fluctuations, exhaust exposure or corrosive conditions, TPA provides stable and repeatable measurement results. A modular evaluation unit allows flexible integration into existing tunnel ventilation, monitoring and control systems.
TPA thus represents a reliable, robust and proven solution for modern tunnel operation and safety concepts – from initial deployment through long‑term operation.

THU – Measurement of Temperature, Humidity and Dew Point for Tunnel Applications
Reliable monitoring of temperature, humidity and dew point conditions in tunnels.
THU is a compact measurement system designed for the reliable monitoring of temperature, humidity and dew point conditions in tunnels. Reliable monitoring of these tunnel climate parameters provides a solid basis for safe operation, infrastructure condition assessment and targeted ventilation control.
THU delivers high measurement accuracy and resolution and ensures stable, reproducible results even under demanding environmental conditions. In addition to temperature and relative humidity, the dew point is calculated directly, allowing early detection of critical conditions such as condensation or icing risks. Optional evaluation functions support the identification of fog and moisture‑related events.
The system is configured via an integrated web interface and can be easily adapted to project‑specific requirements. Various interfaces enable straightforward integration into existing tunnel control and automation systems. The robust housing is designed for permanent installation in tunnel environments and supports reliable operation with minimal maintenance effort.
THU complements the tunnel measurement portfolio of J.con and contributes to transparent, safe and cost‑efficient tunnel operation.
