The Indigo family of smart sensors and transmitters, from Vaisala, has been expanded with some newly released humidity probes. The five new probes can be used with an Indigo host device or another using Modbus protocol. Previously available sensors measured concentrations of gaseous carbon dioxide and hydrogen peroxide. The new offering expands the Indigo functionality into humidity measurement, a mainstay of Vaisala for many years. Humidity can now be measured in:

• Pressurized or high pressure environments, up to 100 bars, with two probe offerings covering differing pressure ranges
• High temperature ovens and similar applications
• High humidity applications where probe heating is required

There is also a new version available for temperature measurement. 

The Indigo family of sensors and host devices are interchangeable, and all can interface with Vaisala's Insight PC software.

Laser Level Transmitter Technology

LLT-1000 Laser Level Transmitter is rugged,
accurate, and easy to use.

Jogler, manufacturer of level measurement instruments, provides a laser level transmitter for industrial process measurement and control applications. The rugged instrument provides continuous non-contact level measurement for process automation and inventory management across an array of industrial applications.

A laser level transmitter can provide reliable measurement of solids or opaque liquids with little interference from granular or foaming surfaces. The technology provides for very long measuring distance, enabling a large standoff from a hazardous location or measuring within a very large vessel. The narrow beam emitted by the transmitter can be easily located to avoid false readings from mixers or other purposeful obstructions within a vessel. The long measuring range, narrow beam, easy installation and high accuracy make the laser based level measurement technology suitable for application in silos, tanks, hoppers, chutes, and bunkers. In addition to being a non-contact measuring method, a laser level transmitter can function effectively through a transparent sight glass installed on a vessel. The complete isolation of the instrument from the process media can be beneficial in many applications.

Rugged Benchtop Refractometer

Refractometry is a widely employed analytical technique used to indirectly measure dissolved solids content of subject liquids. The process employs a refractometer, a device or instrument, to determine the refractive index for a test sample. The measurement is employed throughout science and industry to assess a material's composition or purity.

The refractive index of a substance is dependent, in part, upon temperature and the wavelength of light used in the measurement. Common applications include Brix testing for sucrose level, along with others in the beverage, pulp and paper, chemical, flavor, and fragrance industries. Refractometry is used as a quality control measurement, to assure uniformity among product batches.

Manual refractometers have been available for many years and require human observation and interpretation of a scale reading to obtain a refractive index. Automatic, as well as in-line units are available today that provide uniform accuracy and faster sample processing.

The DSA E-Scan, manufactured by Electron Machine, is an automatic, bench-top critical angle refractometer with a digital readout and temperature-controlled sample chamber. Its compact size and rugged design permit operation in the field and in areas with limited space. The unit provides fast and accurate refractive index measurements of sample liquids.

Freeze Protection for All Sorts of Commercial and Industrial Things

Freeze protection requirements are ubiquitous and take many
forms. Each has a best solution employing a specialized heater.

Keeping process or inventory liquids from freezing, or becoming extremely viscous, can be an important part of any commercial or industrial operation. Freeze damage to equipment, piping, or containers can result in a wide array of consequences, all of them likely to be negative.

Developing an overall plan for freeze protection can be advantageous to attacking each application on an independent basis.

• Having a common vendor for all freeze protection equipment and supplies can help designers develop a knowledge base about how to meet application challenges with specific products, speeding implementation time. Service techs become familiar with applied products and methods, building their skills and efficiency at installing and maintaining applications throughout the facility.
• Identify all locations where freeze protection is needed. Develop a baseline of the methods employed and equipment installed to meet the needs of each location. Good records form the basis for good maintenance and the ability to make decisions regarding the operation and performance of each system.
• When selecting the products or methods to employ for freeze protection, consider the environment in which the hardware will be installed. Will it require protection from physical damage, chemical attack, or extreme weather. Is the installation space considered a hazardous zone, requiring special certifications for the heating equipment?
• The availability and control of applied heat can also be important. Is there a need for the heating system to deliver highly variable amounts of heat across the range of possible operating scenarios, in order to avoid overheating the process or stored materials? How quickly will the system need to ramp up to the desired operating temperature or respond to changes in an operating process?

These questions, and probably others specifically related to your application, should be part of the consideration for freeze protection applications. Enlisting the cooperation of a process heat specialist can apply leverage to your own process knowledge and experience to develop an effective solution to each challenge.
