Fiber Optic Pipeline Leak and Intrusion Detection Utilizing Rayleigh Backscatter and Time of Flight Technologies

Fiber Optic Sensing

Fiber Optic Sensing is a newer aspect of industrial instrumentation that enables real-time measurements of long assets such as pipelines, conveyors, and perimeters. The Praetorian Fiber Optic Sensing System from HAWK is the only system on the market with a single interrogator that measures Distributed Acoustic Sensing (DAS), Distributed Temperature Sensing (DTS), and Distributed Strain Sensing (DSS) all in a single enclosure. The benefit of making these measurements in a single system is those parallel measurements of strain, temperature, and acoustics can be made in their most basic form in real-time by a single processor, allowing for better pattern recognition and faster acquisition and confirmation of events. Another benefit of HAWK's Praetorian Fiber Optic Sensing System is that it ignores false alarms, resulting in one of the market's most accurate and dependable systems. This ground-breaking technology can safeguard assets, equipment, and perimeters. HAWK's Fiber Optic System is modular in design and can monitor up to 50 miles in real-time, 24 hours a day, seven days a week. This type of intelligent monitoring is critical for efficient operation and the protection of valuable assets.

Kayden Instruments CLASSIC™ Series Thermal Dispersion Flow, Level, Interface & Temperature Switches & Transmitters

Kayden Instruments

Kayden Instruments is a leading manufacturer of flow, level, interface & temperature products in the process control community.

Their products assist organizations in the global oil and gas, pipeline, power, mining, chemical, transportation, water and wastewater, food, manufacturing, pharmaceutical, plastics, pulp & paper, and semiconductor industries to improve process efficiency.

Features that make their CLASSIC™ 800 standout amongst the competition:

Patented Design

  • Kayden’s patented designs provide the ultimate performance and features package for flow, level, interface, and temperature sensing.
  • Kayden’s products combine precision welded, highly accurate sensors, extremely rugged enclosures, and advanced digital electronics.
  • The CLASSIC 800 Series combines the failure resistance inherent in Thermal Dispersion technology with the performance and features usually reserved for much more expensive instruments.

Universal Power Input

  • Some manufacturers require upfront specifying of all options, such as relay-energized mode, at the time of order. Still, with the Kayden CLASSIC 800 series, you can select your choice of operation modes by simply pushing a few buttons.
  • The universal power input capability of the Kayden CLASSIC 800 series provides flexibility for use in all power input situations.

Discrete & Analog Outputs

  • Modbus registers via RS-485 4-20 mA analog representation of Thermal Signal.
  • Two SPDT sealed relay contacts rated @ 4 amps resistive 230 VAC or 24 VDC maximum.


  • Adjustable Set Point Deadbands
  • 4 Adjustable Independent Switch Point Timers

Advanced Diagnostics

  • Kayden’s CLASSIC 800 series uses an advanced microprocessor to perform continuous self-test diagnostics on the electronics and the sensor elements.
  • Any open or shorted connection will result in a FAULT indication that deactivates all relays and disables the heater circuitry.
  • An internal watchdog circuit ensures that the microprocessor code is performing as expected, and a secondary external watchdog circuit confirms the microprocessor itself is functioning. Both circuits force the contacts open, illuminate the Fault LED, and force the heater off in a malfunction, preventing the possibility of a “run-away” heater or a high thermal offset.

Intelligent User Controls

  • The Kayden CLASSIC 800 series Display Panel features very bright LED indicators for easy viewing even in direct sunlight.
  • An adjustable power-on Start-up Bypass Timer is accessible from the Display Panel for low-flow alarm pump protection applications. This feature makes it possible to disable a pump on low flow and have it automatically restart after a predetermined time in the event of a power interruption.
  • Four adjustable delay timers introduce repeatable time delay into the (setpoint) relay trip function. For example, in a pump protection application, this function will shut down the pump after the switch sensor has gone “dry” for the pre-set time (delay) limit.
  • The Kayden RCM (Remote Communications and Monitoring) Software allows all the settings to be configured remotely and saved as a file, transmitted as an email attachment, and printed for future reference.
  • The Kayden RCM Software includes the option of locking the CLASSIC 800 Series Display Panel to eliminate field adjustments or tampering.
  • Modbus allows multiple Kayden units to be connected to the same communications bus (via RS-485) and monitored simultaneously.

Combating Droop In Self Contained Pressure Regulators

Combating Droop In Self Contained Pressure Regulators


Sometimes referred to as the ‘Proportional Band’ or ‘Offset’, droop is an inherent characteristic in all self-operated and pilot-operated regulators. Droop is a decrease in outlet pressure from the set value due to an increase in media flow rate.

Download this white paper on combating droop in self-contained pressure regulators. Learn about what you need to consider, what the droop effective is, typical applications, how to reduce droop and how to choose the right valve.

The Hawk Measurement OptioLaser L100 and L200 Laser Level Transmitters

Hawk Measurement OptioLaser L100 and L200

The Hawk Measurement OptioLaser L100 and L200 Laser Level Transmitters are perfect for measuring the level, distance, and the location of solid and liquid surfaces. 

The OptioLaser L100/L200 is a non-contact laser sensor used to measure the distance to solid and liquid surfaces, slurries, or murky water. Solid surfaces can be anything from a metal plate on the side of an overhead crane to the top of material stored in a silo. With an easy-to-use menu system, the OptioLaser is configurable for either distance or level measurement. The high accuracy, long-range, and fast update rate make this the ideal sensor for many different applications.

The OptioLaser uses a unique laser that has a very narrow beam that can measure long and short distances at practically any angle. Furthermore, the OptioLaser L100/L200 is made entirely of stainless steel and is exceptionally tough and perfect for the harshest conditions. Their accuracy and durability make the OptioLaser ideal for a wide range of applications and industries.

Details of the Eurotherm Series 2000 Obsolescence and the EPC3000 Replacement

Over the last 25 years, the 2200 and 2400 controllers have been two of Eurotherm's longest-running and best-selling control offerings. They have proven themselves to be highly versatile and reliable for all sorts of applications. However, many have changed since the '90s, including significant advances in microelectronics technology. Eurotherm incorporated these advances into new and improved offerings. 

That's why Eurotherm decided to make the 2200 and 2400 series controllers obsolete, effective January 31st, 2021, with repair and servicing for these ranges available until 2025. 

As a replacement for these ranges, Eurotherm recommends the EPC3000 series of programmable controllers. They offer the same functionality you've come to expect, along with additional improvements to help meet the needs of today. They also feature very similar wiring to both the 2200 and 2400 series controllers. They are available in the exact three DIN sizes. 

Installing the controller into existing panels is friendly and straightforward. Plus, the EPC3000 series has been designed with cybersecurity in mind and certified to meet the stringent requirements of Achilles Communications Robustness Testing Level 1. You'll also benefit from enhanced precision control, exceptional thermal stability, and noise rejection. It's also more user-friendly, featuring a graphical wiring environment to help create applications. Users can select the function blocks they wish to use in their application and then connect them using 'soft wiring .' There is a pictorial view of the configuration. Ethernet communications are supported via a standard RJ45 connector, providing fast access to the process, and diagnostic information as Eurothermll as connectivity to an external PLC or a plant SCADA. 

The EPC3000 programmable controller offers exceptional value and packs many features typically only available in high-end control offerings. Whatever your process, the EPC3000 range can help you achieve the required stability, accuracy, and repeatability.
