Description The fibre optic pressure sensor P-01 consists of a membrane that is connected to a FBG mounted under pre-strain. When pressure is applied to the membrane, the membrane will deflect resulting into a change in the FBG strain value and hence also in a change of the reflected FBG wavelength. The head of the pressure sensor is foreseen of a thread that allows connecting the sensor to pipelines, valves and vessels. In order to compensate for temperature influences, a high resolution temperature probe is integrated within the housing. The housing is made of stainless steel and is terminated with an optical connector using a plastic tubing. Tubing lengths and connector can be specified following the needs of every application. The sensor is single connectorised but can on request also be designed for series configurations. Features The pressure sensor P-01 can measure pressure and temperature with a resolution of 0,05% Full Scale and 0,1 °C respectively and an accuracy of 1% Full Scale and 1 °C respectively. The pressure range can be chosen between 1 and 150 bar. Applications The pressure sensor can be applied for flow control in all sorts of pipelines and liquid level measurements in reservoirs and others.
