Pressure sensor (with integrated temperature sensor)

Fiber optic sensor for water level and fluid pressure monitoring

The fiber optic Pressure Sensor enables the measurement of pressure ranging from 1 to 600 bar. It can be used for flow control and liquid level measurements in reservoirs and pipelines. It can also measure ground and water levels using porous stones as an accessory tool.

  • 100% passive sensor without the need for power supply
  • broad pressure sensing range
  • integrated temperature compensation

100% passive sensor

The sensor works without a power supply and therefore easily monitors places without access to power and hazardous or inaccessible areas.

Broad pressure sensing range

The Pressure sensor has a very broad sensing range from 1 – 10 bar to 1 – 600 bar.

Integrated temperature sensor

The temperature compensation is achieved by configuring the sensor either with two differential FBGs or one FBG and a temperature sensor.

Watertight and ruggedized housing

Watertight and ruggedized housing guarantees optimum performance even in harsh environments  and hazardous or inaccessible areas.

Ground and seawater measuring

The pressure sensor can measure ground or seawater pressures by combining it with a porous stone.

Customized pressure range

The pressure range can be customized by changing of the measuring membrane.

Long distance signal integrity

The Pressure sensor features excellent signal integrity, hence the optical cables can carry correct, uncorrupted values for very long distances.

Excellent long-term stability

The Pressure sensor is highly durable and reliable even in demanding environments. It is, therefore,  suitable for long term field operation.

Immune to EMI/RFI

This fiber optic sensor enables operation even in harsh environments and hazardous areas. The advantage is immunity to electromagnetic/radio frequency interference.


The sensor can be used alone or incorporated into a large sensing network regardless of sensor interconnections.

Installation costs

Installation and cabling for optical sensor networks are much less expensive and cumbersome than comparable electronic gauge networks.
