OptaSense - Model ODHF -Interrogator Unit
The ODHF Distributed Acoustic Sensing Interrogator is an advanced fiber optic device designed for a wide range of applications, including both quantitative and non-quantitative sensing. This device is a successor to the ODH3.1 and includes multiple operational modes; it can function in a Quant mode for distances up to 10 km and in a Non-Quant Intensity Only mode for distances up to 50 km with a 10-meter output channel pitch. The ODHF offers high-resolution capability with a 1.3-meter resolution in intensity mode, which enhances its versatility for various applications. The built-in multiplexer supports sequential interrogation of up to four cables, providing a cost-effective solution for continuous asset monitoring over the lifecycle of equipment. Additionally, the OptaSense DxS browser software enhances its functionality by allowing real-time data visualization, and enabling complex workflows for managing distributed acoustic sensing data.
Versatile Distributed Fiber Sensing for Quantitative and Non-Quantitative Applications
The ODHF is a unique device and the successor to our ground breaking ODH3.1 Available with the ability to operate in Quant mode up to 10km and an Intensity Only Non-Quant mode to 50km with 10m output channel pitch. With a high resolution, 1.3m resolution intensity mode, the ODHF is a truly versatile instrument. An integrated multiplexer allows up to 4 cables to be interrogated sequentially. This gives provision for cost-effective through-life continuous asset monitoring.
