Using CCTV and intelligent counting units, a video vehicle traffic counting system achieves over 98% accuracy in all conditions: day and night in rain, sun and snow. Cars are counted as they pass through the counting zone One camera covers several exits of a junction. At four-way junctions, for example, the system provides multi-directional counts for vehicles turning north, south, east or west and coming from any direction - making the system very cost-effective. There is no limit to the number of roads and junctions on which traffic can be counted using the scalable CCTV system.  Local video analytics minimises bandwidth use. Traffic counts are uploaded in real-time via the internet, so traffic engineers can view live (down to 15 m...

Certification is one of the way to prove your knowledge, skill and authority over the subject of your profession. It improves your understanding of the subject and then applying it in the field gives you immense satisfaction and confidence. International Society of Automation (www.isa.org) certifications provide an objective, third-party, unbiased assessment and confirmation of a person's skills, experience, knowledge and proficiency. They give accredited individuals the opportunity to stand out from the crowd and be recognized. Over the last couple of years, ISA certifications, ISA-CAP in particular, has achieved global recognition, which is a great feature in today's competitive market. ISA-CAP covers all the possible domains of the Instr...

What are the attributes and characteristics that differentiate the DCS system from the PLC. The topic has remained under debate for long, and especially today when we have already entered into new era of Hybrid Distributed Control Systems, it is not an easy task to select and differentiate the advantages and drawbacks one can get from different systems for the intended application. Let us first roll back to the history of DCS and PLC. Process plants used to have long series of panel mounted Single Loop Controllers (PID controllers). In Single loop controllers, the control was non-centric and distributed. In early 80s, manufacturers came up with an idea of integrating all the PID controllers to a central digital system still maintaining the ...

Our cartridge valve are equipped in most of industrial machines, engineering projects, various systems and units plays main roles or parts, being accepted by the markets across numerous industrial equipment or...

Automated passenger sensing system provides reliable data at low cost, no matter how busy the service. Using CCTV and intelligent people counters, the sensing system logs numbers of people getting on and off buses, trains or other public transit system at each stop or station. The passenger sensing system on its own provides valuable information, but when you add vehicle tracking operators can see where a bus or train is as well as how many people are on it The system has saved a British bus company thousands of pounds per bus. By automatically counting people on and off their buses, the company could cross-check passenger numbers with ticket machine transactions. With proof that they had more passengers than transactions, managers took ...

PROTEO is a new IPC pump control system that embeds several innovative and advanced features. PROTEO provides total pump protection, process oriented performance control and overall machine diagnostic and protection.The system is designed for a completely automated machine management, giving to the operator  the  full control of pump/process operative conditions  with an easy and friendly graphical interface. PROTEO main benefits: energy costs reduction: VFD control technique and model based control architecture allows to minimize energy consumption operational costs reduction: increasing Pump reliability, full automated protection and auto-diagnostics tasks allow reductions of downtimes and relative costs for maintenance and production ...

The simplest calibration procedure for a linear instrument is the so-called zero-and-span method. The method is as follows:1. Apply the lower-range value stimulus to the instrument, wait for it to stabilize2. Move the \zero" adjustment until the instrument registers accurately at this point3. Apply the upper-range value stimulus to the instrument, wait for it to stabilize4. Move the \span" adjustment until the instrument registers accurately at this point5. Repeat steps 1 through 4 as necessary to achieve good accuracy at both ends of the range An improvement over this crude procedure is to check the instrument's response at several points between the lower- and upper-range values. A common example of this is the so-called -ve-point calib...

The Modbus protocol is still one of the most widely used automation protocols in the process industry. If you are a technical person who has had to implement control systems, especially PLC-based control systems, then you would know that a knowledge of Modbus is essential in connecting equipment from different manufacturers. Furthermore, Modbus more often than not is implemented over the RS485 physical medium. So knowing Modbus RS485 networking is essential for control systems implementation. But most professionals learn about the Modbus protocol by scouring the internet for bits and pieces of information, which takes time and also can be quite confusing. This is what happened to me when I came out of university with a degree in Elec. Eng....
