Quick Overview

• Designed for console installation in CTU cabin
• Rapid response analogue weight dial
• Clear digital speed and depth display
• Simultaneous acquisition from two depth encoders
• Composite depth function
• English and metric depths at the touch of a button
• ATEX Zone 1 certified version available (as shown)

Hardware Configuration

Sirius alpha has inputs for:

• Two load-cells, for example, pipe heavy and pipe light

• Two shaft encoders, for example from a NOV CTES Depth Measurement System head, sold separately.

  Input channels may all have isolation barriers safe to CENELEC EEx ia, allowing the sensors to be positioned even in Zone 0 hazardous areas if required.

Sirius Alpha has outputs for:

• All incoming signals, allowing 'pass-through' to other data acquisition systems, e.g. NOV CTES Orion.

• A composite quadrature output, to feed another data acquisition system with the computed composite depth.

• A serial data stream of all currently displayed values for remote processing and recording. Sirius Alpha is powered by a versatile broadband DC input, 9-18V, ideal for 12V unit or truck electrics.
  

Input channels have isolation and are intrinsically safe to EEx ia, allowing the sensors to be positioned in Zone 0 hazardous areas if required.

Sirius alpha is powered by a broadband DC output, 9-18V.

Data Manipulation
Sirius Alpha displays weight on a large, clear, analogue dial. The dial pointer has a rapid update rate giving the weight reading a 'feel' much like a hydraulic load cell.
A simple rotary knob allows tare or offset of the weight at any time. The crisp, two-line LCD display shows speed and depth for one encoder. The second encoder or the
composite value can be chosen from the option buttons at any time. All depth values are saved at power off. Each depth can be individually offset. All depths can be zeroed together. Depth and speed can be displayed in English or metric units at the touch of a button.

Cutting Edge Technology
The system is based around a single board computer and a DAB300 data-card, pictured
left. The flexibility of this approach comes from the powerful computing power
available, allowing the system to be reconfigured and customized in many different ways.
