The Perma Pure Hybrid Sample Gas Cooler

Sample gas coolers condition the sample gas of an analyzing system by passing it through a heat exchanger and cooling it down. Removing any moisture from the gas is a critical step in sample gas conditioning, accomplished by using suitable coolers to lower the gas temperature below the dew point, allowing water to condense. The dew point must be as stable as possible for a repeatable analysis result even when the ambient temperature varies. Sample gas coolers have broad applicability in the cement, petrochemical, steel, power generation, and process industries.

The Perma Pure Baldwin Hybrid Sample Gas Cooler combines the superior performance of Perma Pure’s Nafion™ based drying technology with the functionality of a traditional thermoelectric cooler. Powered by compressed air, this nonelectric cooler achieves dew points lower than 0˚C, helping to prevent problems associated with condensation. The patented mechanical design is ideal for locations with limited or no access to power or other areas where a nonelectric product may be desirable.

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

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.

Adjustments

• 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.

Bubbler-Tube Liquid Level System

bubble-tube liquid level measurement system.

Measuring liquid level in an open tank or vessel can be accomplished in a number of ways, all of which require some arrangement of instrumentation to either infer the liquid level from the measurement of a related physical property, or directly deliver the liquid level visually using a scaled gauge arrangement. One indirect method of level measurement is often referred to as the bubbler or bubble-tube method, so named because it employs a purging gas that continually vents from the bottom of a tube extending into a tank of liquid. Through a simple apparatus, the level of a liquid can be inferred by the amount a back pressure exerted upon the gas flowing through the tube.

Probably the greatest advantage of this method of liquid level measurement is that the media does not contact the sensing instrumentation, protecting the instrument from damage by the media, and the media from possible contamination from the sensor. The only portion of the apparatus in contact with the liquid is a tube immersed into the tank. Basically, a purge gas flows through the immersion tube and may bubble out the immersed end of the tube, which is open to allow the contained liquid to exert a hydrostatic pressure on the purge gas. The back pressure on the gas that is exerted by the liquid contained within the tank will vary directly with the depth of the liquid. The back pressure can be correlated to a liquid level. Further calculations, which would include the tank shape, dimensions, and the liquid density can provide an indication of the volume and mass of the liquid.

It is feasible to create your own bubbler system, but the cost in human resources to design, coordinate, procure, and assemble all the components is unnecessary. ControlAir provides a completely designed and pre-assembled unit, compact and ready to run on your application. More information is included in the datasheet below. Share your process measurement challenges of all types with measurement specialists. Leverage your own knowledge and experience with their product application expertise to develop an effective solution.
