Codel Monitoring Solutions
The TunnelTech 101 Visibility Monitor (VIS), is an essential part of any road or rail Tunnel Monitoring safety system. Firstly, it monitors the Visibility within the tunnel and ensures that the tunnel ventilation system provides sufficient clean air for drivers to clearly see the road ahead.

Secondly, used in combination with other TunnelTech 101 VIS monitors, the operator can quickly detect the focus of the fire if it is also equipped with the optional PT100 temperature sensor to accurately measure ambient air temperature in a range of -15 to 1050C.

Fully configurable analog and alarm outputs are exportable to the tunnel data acquisition
system to provide real-time visibility data. This data is also exported via the RS 485 serial port along with the temperature data. This link delivers MODBUS RTU encoded data to a SCADA system located in the tunnel control center and/or a local display module. In addition, the IP65 rated enclosure is coated to resist attack from aggressive gases, road salt and to resist the effects of extreme heat.

In Tunnel Monitoring applications where extremely low temperatures may be experienced, optional transmitter and receiver insulation jackets are available to reduce the effect. Another option is a local display, driven from the RS485 output which enables operators to view output data, diagnostics and alarm setpoints.
