Process safety experts continually seek sustainable ways to improve the performance of safety critical loops, achieving risk reduction and safety goals in a cost-effective manner. Some view a reduction in complexity of safety related protocols to be a positive development. Traditional or historical approaches to deploying full blown safety systems were generally associated with great expense and high complexity, and still came up short on delivering the needed levels of risk reduction. Process control device and equipment manufacturers have responded with newer technologies and products that better address the safety needs of industrial processing.

In sensor subsystems, United Electric’s certified safety transmitter for pressure or temperature provides a less costly, simple path for process designers, instrument and control engineers, and maintenance personnel. The Series One Safety Transmitters combine several useful safety and monitoring functions into a single, easy to deploy device. Products are available for gauge pressure, differential pressure, and temperature applications.

Energy Calculator Simplifies Chilled and Hot Water Usage Monitoring

Yokogawa Model 212 Heat Calculator

Early in my professional career, I was a sales rep calling upon building engineers, maintenance technicians, and lots of HVAC related people. One encounter I had, many years ago, has always stayed with me. I was prattling on to a building engineer about whatever gear I was trying to promote for his chilled water system, and I must have really missed the mark. The engineer, clearly a man of superior experience to mine, stopped me in mid sentence. "You know what flows through these pipes?", he said, referring to the chilled water system. In my defense, I was very young and inexperienced at the time, but I did answer "Chilled water". My building engineer friend bellowed out, "Wrong....money flows through those pipes". That single encounter had a lasting impact upon how I viewed HVAC systems.

Energy costs for heating or cooling a building can be the single largest line item on the cash outflow summary for an operation. Much effort and expense is put into efforts to maximize energy efficiency and conservation. Monitoring of usage patterns related to the chilled or hot water system can provide useful information for developing new conservation strategies and verifying the impact of any steps taken to reduce consumption.

The Yokogawa Model 212 is an affordable and easy to install and use device that will provide a stream of usage data. A key feature of the Model 212 is its ability to interface with a broad range of flowmeter devices, including vortex and magnetic flowmeters with pulse outputs, positive displacement and inferential water meters, turbine and paddlewheel flowmeters. This flexibility allows the user to select a companion flowmeter that will suit their accuracy, budget, and operational requirements.

The Heat Calculator has four modes of operation to totalize the usage patterns in a manner that best suits the needs of the user. Additionally, the unit can interface with a building management system and includes internal data logging capabilities. Other features are described in the product data sheet I have included below.

Even small chilled and hot water systems can benefit from usage data derived from a monitoring system such as the Yokogawa Model 212. Share your system challenges with a product specialist. Combining your process and system knowledge with their product application expertise will produce effective solutions.

Bimetallic Thermometers With Adjustable Angle and Rotating Head Make Installation Simple

Bimetallic Thermometer

A bimetallic thermometer relies on the deformation of a bimetal spring or strip in response to a given temperature. The mechanical deformation is transformed into rotational movement of the indicating needle on the instrument face, where the corresponding temperature can be read by a technician or operator. This design principle has been in use throughout laboratories, kitchens, and industry for many years and has proven to be predictably accurate, stable, and rugged.

The major advantages of the bimetallic thermometer are its relative cost, ease of use, and ability to function without any power source. While this class of instruments provides operability up to +1000°F, the operating principle does not tend to provide similar accuracy at very low temperatures.

When applying dial faced thermometers, the main considerations beyond selecting the appropriate temperature range are the diameter of the dial and the mounting arrangement. US Gauge, an Ametek brand, provides a line of bimetallic thermometers for industrial process applications with a large degree of built-in flexibility to make selection and installation very simple. Three and five inch dial faces are offered, along with a selection of temperature ranges and stem lengths. The stem can be adjusted to almost any angle to provide good view of the face, and the head can be rotated over 180°.

Provided just below is a data sheet and description of the ADJ Series from US Gauge. Share your instrumentation challenges with the product application experts at Miller Energy. Combine your process knowledge with their product expertise and develop the the best solutions.

Industrial environments present a wide range of challenges to the process designer or operator looking to install sensitive instrumentation or controls. Not all devices come with integrated enclosures suitable for all environments. The responsibility for properly housing equipment, controllers, and other instruments can fall on the process designer or operator.

There are numerous considerations in the design and selection of an enclosure, especially when the application drifts beyond the range of commonly available sizes, configurations, and materials of construction. Here are some thinking points for you.

• Ignition Hazard Level: Areas or locations with hazardous classifications will require special enclosure designs and features for compliance.
• Climate: If outdoors, consider the range of local weather conditions and their potential impact on the longevity and performance of the enclosure, its ability to protect whatever is housed within.
• Access: Do operators need quick access to contained equipment? If so, appropriate latches or other closures that allow interior access without a need for tools may be in order. Security concerns may warrant locking capability. A clear panel installed in a door can provide visual access to instruments safely contained within the enclosure.
• Corrosion: Wet environments or locations near seawater or other corrosive elements can call for upgraded coatings or materials of construction that will prolong the useful life of the enclosure.
• Enclosure Cooling or Heating: Depending upon the surrounding temperature or the characteristics of equipment housed in the enclosure, heat removal or supplementing accessories may be integrated into the enclosure design.
• Size: Consideration given to possible additions to the original array of instruments or devices to be contained can save substantial time and money if a future expansion is in order. The size of the enclosure should provide for any clearance  recommended by device  manufacturers for their installed components. Provide adequate servicing space for field technicians to perform any necessary tasks related to housed equipment.
• Penetrations: Conduit or other penetrations required for proper operation and installation can be accomplished more precisely, and often at a lower cost, in the factory than in the field. Carefully laying out and coordinating the installation of connections to the enclosure can save time and trouble in the field.

Certainly, there are numerous other elements of enclosure design that may be taken into account for differing installation requirements. Share your project requirements with application specialists and reach the best solutions by combining your process knowledge with their product expertise.

Simplifying Plant Safety Instrumentation

Safety implementation typically is accomplished by a group that includes plant instrument engineers and technicians. They are charged with developing simple and reliable solutions that increase safety and reduce risk. Safety related events can involve the question of when to shut a process down. These decisions can hinge on the level of key process variables such as flow, level, temperature and pressure. All must be within their specified range at various locations throughout the process, whether within chemical and petrochemical plants, refineries and power plants, or other processing operations. Critical points of measurement can include anything from process vessels to eye wash stations.

For such point safety applications, a properly designed and implemented digital switch with self-diagnostics can be an important part of the answer. As an element of a multiple technology solution, a digital switch-based approach can help eliminate common-mode failures, significantly improve response time, achieve needed safety integrity levels (SILs), and simplify plant safety instrumentation.

United Electric Controls has authored a white paper entitled "Simplifying Plant Safety Instrumentation" that provides some insight into deployment of safety controls. The entire white paper is included below and will prove to be useful reading.
