Rugged Monitoring is a new company formed by veteran fibre optic engineers. This industry leading team has over 100 years of combined experience, and is committed to delivering customisable fibre optic based sensing solutions for challenging applications.

Precision, reliability, and high performance are Rugged Monitoring priorities.

Fibre optic temperature sensors are highly responsive, intrinsically safe and immune to external influences such as electromagnetic fields, corrosion, and vibration. Rugged Monitoring offers two portable instruments for temperature measurement, and five types of sensor.

L201 Series Monitors

The L201 is a compact 2 to 4 channel fibre optic temperature monitor designed for use in a wide range of demanding applications. The instrument has a measuring range of -269 °C to +300 °C with complete immunity to RFI, EMI, microwave and high voltages. This makes it the optimal choice for environments where extreme conditions limit conventional temperature sensor/monitor systems.

Compatible with a wide range of fibre optic temperature sensors from both Rugged Monitoring and other companies, the instrument is based on proven GaAs technology with inbuilt redundancy. It also does not require calibration and has been designed to offer simplicity of use with plug and play operation.

The multi-channel L201-X (shown right) collects data from up to 8 sensors (expandable to 256) and has been designed to integrate easily into existing systems via serial comms or analogue ports. The 201-X monitor is supplied with Rugged Connect: software designed with the needs of test platform or industrial process monitoring integration needs in mind.

T301 Series Monitors

The T301 series is a rugged 8 to 24 channel fibre optic temperature monitor designed for use in environments where extreme conditions limit conventional temperature sensor/monitor systems.

The instrument has a measurement range of -269 °C to +300 °C; complete immunity to RFI, EMI, microwave and high voltages; and is compatible with a wide range of GaAs fibre optic temperature sensors from both Rugged Monitoring and other companies.

The T301 is designed for data collection and ease of integration into existing systems. As such it is equipped with an RS-485 interface as standard. Optional interfaces include: RS-232, Gigabit Optical Ethernet, or simple 0-10 V analogue outputs.

The supplied software, which is capable of reading up to 256 channels simultaneously, has been written with the needs of industrial test and process monitoring in mind.

Lsens Series Sensors

Rugged Monitoring sensors offer complete immunity to RFI, EMI, NMR and microwave radiation. A typical probe consists of a PTFE protected glass fibre with a GaAs-crystal (Gallium Arsenide) at the tip. There are currenly five types of sensor available:

For -200 to +250 °C
Type Description Tip dia. Vaccum Immersion
Lsens-B Unprotected probe tip
No Teflon protection for the last few centimetres [default is 5 cm]
0.3 mm Yes No
Lsens-P   Thin-wall polyimide protective cap as standard 0.7 mm Optional Yes
Lsens-T Teflon sheath
Accuracy <±1 °C | Precision 0.2 °C | Response time 250 ms
1.1 mm Optional Yes
Lsens-R Optimised to resist liquids and pressures up to 3 bar
Tough polyimide sheath and Teflon protective cap
1.7 mm Optional Yes
For -269 to +85 °C
Lsens-C Cryogenic tip
Optimised for very low temperatures (~ 4 K) and vacuum
[Polyimide on the last 10 cm]
0.7 mm Yes Yes


The run length from sensor to monitor can be several kilometres without any effect on the accuracy of the measurement results.

Technical data for the monitors and sensors can be downloaded as a PDF from the Documents menu upper right.
