The One Series Safety Transmitter for Increased Plant Safety

united electric safety transmitter

The power generation market is beginning to emphasize the importance of plant safety. This was made clear to all attendees during the keynote session at the Power-Gen International Show in Orlando held in early December. Ms. Kimberly S. Greene, executive VP and COO of Atlanta-based power generation Southern Company made a passionate plea for better safety standards within plants that fall under the Southern Company umbrella, and to begin thinking about plant safety and investing in safety automation technology to provide some solutions. According to Ms. Greene, Southern Company facilities sent 300 workers home with workplace injuries in 2014.

In one case this year, a 44-year employee died on the job, causing Ms. Greene to make an emotional plea to all attendees and plant managers to move safety to the top of their priority lists. For the power generation market, plant safety has not (yet) received the same level of attention when compared to the hydrocarbon processing market. Ms. Greene’s statistics reminded us all that functional safety must be considered across many industries that include harsh and hazardous operating conditions and processes.

The One Series Safety Transmitter is a pressure and temperature monitoring transmitter-switch that provides a NAMUR NE 43 standard 4-20 mA analog output. Its programmable high-capacity solid-state safety relay output enables the fastest emergency shutdowns in the industry.

The One Series Safety Transmitter was designed with features that simplify installation, improve productivity, and eliminate nuisance trips. The instrument is password protected to prevent unwanted parameter changes; eliminating the risk of tampering. The large backlit digital display provides process variable, status, self-diagnostics and field programming information.

Some of the advantages of using UE’s safety transmitter are:

  • ​4-20 mA analog output with field scaling capability
  • ​100% programmable high-capacity safety relay for switch mode, set point & deadband
  • ​Effectively replaces a gauge, transmitter, and a switch to reduce potential leak paths
  • ​Additional discrete outputs to facilitate voting logic schemes
  • ​The industries highest safe failure fraction (SFF) of 98.8% as certified for use in SIL 2 by exida

Introducing the Groundbreaking One Series Safety Transmitter

At United Electric, we have a proud history dating all the way back to 1931. How does a company remain so successful for such a long time?

Some of the ways are through our uncompromising commitment to quality, our focus on innovation, and our efficient operations that span the globe. Another way is through our continuous focus on growth and technology—specifically on adding new products to our line that meet customers’ demands and change the industry for the better.

In that vein, we’re very excited to officially introduce and offer our new One Series Safety Transmitter, a groundbreaking product that will truly be a game-changer, and will further solidify our role as world leaders in safety, alarm, and shutdown applications.

The One Series is a unique product that goes beyond all other safety transmitters, designed to solve problems related to the design, operation, maintenance, and modernization of a Safety Instrumented System (SIS).

The One Series Safety Transmitter is a universal multi-function device that allows the user to choose how to operate the product, either as a simple transmitter, a switch to control the final element directly via the Safety Relay Output (SRO), or to use the discrete outputs for voting logic systems. Through the SRO, alarms and emergency shutdowns occur directly through the instrument, saving time when it’s most crucial. In fact, the response time is less than 100 milliseconds.

Other features include a built-in Safety PLC function, discrete 24 VDC outputs, and an extremely reliable high Risk Reduction Factor (RRF). It’s also secure—an exceptionally critical factor—as it is not available with HART, which has proven to be vulnerable to cyber-attacks.

The product comes standard with a 4-20 mA output along with the SRO, and it fits perfectly with newer safety systems as a 2-wire loop powered transmitter, or with older legacy safety systems that require switch control to a plc or final element.

Fully certified by exida for use in functional safety applications, including SIL 2 and SIL 3 (when redundancy is included), this is simply the easiest, most effective way to ensure safety and immediate response.

Replacing Mechanical Switches in a Safety Application

Is it that time to upgrade your plant’s safety instrumentation? If your case is the typical upgrade move from mechanical switches to a transmitter, do you know specifically which type of transmitter you should be getting? What is the best means of replacing mechanical switches in a safety application?

united electric safety transmitterIt’s often necessary to replace mechanical switches because they are considered blind devices; they cannot warn you when they have become faulty, nor can they be relied on completely, as they have many moving parts. This can result in the sensor cracking, the piston sticking, or the micro-switch wearing out. Unless the switch is tested on a regular basis, there is no way to determine when problems exist. This is the main reason many facilities are moving towards transmitter upgrades.

Typical transmitters, however, can be very costly for a plant. Not only is the instrument itself expensive, but there are many hidden costs as well. A transmitter will require major input to the control system, including analog requirements, cabling, and the reprogramming of the control system to accommodate the updated continuous signals that process pressure changes. With all of this, the programming tasks become increased.

By now, you should realize that United Electric Controls places safety and quality above all else. So what would we recommend using instead? Our One Series Safety Transmitter. Since the One Series Transmitter contains a built-in switch function and has a self-diagnostic feature, programming would remain the same in the upgrade process. This way, you are saving money and time in the upgrade process without compromising an ounce of safety.united electric safety transmitter 2

We designed the One Series Safety Transmitter from the ground up with the intent to use it specifically in safety applications. In comparison, other transmitters are meant for process applications, meaning accuracy is high but not necessarily functional for safety situations. When it comes to safety, high quality, designed safety transmitters are the best option to go with.
