Watlow Limit and Scanner Controllers

Anderson-Bolds Provides High Quality Watlow Temperature Control Products

Watlow LIMITS AND SCANNERS

Watlow single and multi-loop limits provide cost-effective solutions for single- and multi-channel, temperature monitoring. Limits monitor the process value where thermal system protection is needed, closing a contact output for normal operation and opening that contact to shut down the process or equipment when the value is outside the safe range.

Various configurations offer user-selectable or fixed-configuration sensor options including thermocouple, process, RTD and thermal switch inputs as well as user-settable or fixed limit values. Models with displays have user-selectable temperature units. Other features include sensor break protection, industry standard I/O options and UL® and CSA approval. All limits and scanners are RoHS compliant. Limits have FM approval for performance in limit (Over Temperature) applications. Watlow limits are designed and manufactured to withstand harsh industrial environments and come with a three-year warranty.

The EZ-ZONE PM Express limit controller is ideally suited for basic applications and usage levels.

The EZ-ZONE PM Express limit controller is the next generation of controllers leveraging the strong legacy of Watlow's SERIES 94, SERIES 945 and SERIES SD limit controllers where easy-to-use features are needed for basic applications. It includes one universal input and the option for up to two outputs and is available in 1⁄32 and 1⁄16 DIN panel mount limit controls packages.

The EZ-ZONE PM Express limit controls are a great addition to the EZ-ZONE PM family which includes two other controller versions, the EZ-ZONE PM integrated controller and the EZ-ZONE PM temperature and process controller. This family provides an ideal platform to perform many applications.

RM SCANNER MODULE

The EZ-ZONE® RM high-density scanner module can be used in conjunction with any EZ-ZONE RM family module as a monitor or to provide additional logic function to a system. The scanner module can also be used as a stand alone product for multiple inputs of monitoring applications. The EZ-ZONE RM high-density scanner module provides 4, 8, 12 or 16 loops of monitoring per module or up to 256 monitoring loops per system.

Carlo Gavazzi Earth Leakage Monitors

Carlo Gavazzi Earth Leakage (grounding) Monitor Relays

For quotes and information, please go to our Contact Anderson-Bolds page  HERE.

CARLO GAVAZZI is proud to announce the launch of two new Earth Leakage Monitoring Relays, the DEA71 and DEB71. When used in conjunction with a CTG Series Core Balance Current Transformer and appropriate circuit breaker, they provide machine protection against fault currents, and help to reduce fire hazards. These earth leakage relays react to small changes in current which can occur due to insulation or grounding failure.

Two models, each offering choices of threshold ranges, allow users to find the right solution for their unique requirements. The DEA71 features fixed trip levels which offer time-saving installation, with a reliable tripping level and safety against tampering. The DEB71 provides ability to adjust trip levels and includes an adjustable time delay; a lockable front cover provides further tamper protection.
A key advantage offered by DEA71 and DEB71 is avoidance of nuisance tripping in the circuit, in accordance with the EN 60947-2 Annex M norm. Two separate alarm outputs allow for a warning signal to be generated before a shutdown is necessary. Their compact (35mm wide) housing preserves valuable panel space.
The DEA71 and DEB71 from Carlo Gavazzi perform crucial monitoring of earth leakage, prolonging machine life by limiting damage from ground faults as well as reducing fire risk. They conform to global standards such as UL 508, CSA C22.2 and EN 60947-2 Annex M.
The features of the DEA71 and DEB71 Earth Leakage Relays include:

 

•   DEA71 includes two models with fixed trip setting: 30 mA and 300 mA
  
•   DEB71 includes two models with adjustable trip levels: 30 mA to 5 A and 300 mA to 30 A
  

 2 SPDT relay outputs, for warning and for alarm  24 VAC to 240 VAC power supply
 NORM DIN-rail housing 35 mm
 Lockable lid on adjustable models (DEB71)

The DEA71 and DEB71 Monitors and CTG Series Core Balance Current Transformers are available from

Sure-Foot Prevents Slip and Falls

SURE-FOOT Mats and Stair Treads and Tape

How Anti Slip Tape Keeps Workers Safe in the Oil & Gas Industry

Oil and gas is one of the fastest growing labor sectors, and with growth comes more liability.

A 2017 report showed the oil and gas industry has one of the highest rates of severe injury. With the sector’s constant growth, these injuries will continue to plague workers and cause slowed production, excess time off, long-term disability or even death.

You cannot eliminate the uncertainty surrounding labor-intensive jobs like those in the oil and gas industry but knowing about environmental hazards can help mitigate some of the dangers that lead to critical error and injury.

Slips, Trips, and Falls

Like so many other industries, prominent workplace hazard in the oil and gas industry lead to a slip, trip, or fall.

According to Occupational Safety and Health Administration (OHSA), most general industry accidents happen due to slips, trips, and falls. They also cause 15% of accidental workplace fatalities, second only to motor vehicles.

Slips, trips, and falls don’t just impact the worker, but they constitute a considerable amount of workers’ compensation and medical bills, over $70 billion yearly in the U.S., according to the National Safety Council.

Environments vary, but whether a workplace is involved in discovering, producing, obtaining, refining or distributing oil or gas, the ground can become slick from various liquids.

The combination of oil and water on steel surfaces can be a recipe for disaster for workers hustling through high traffic areas.

While metal products in these types of environments are often covered in slip resistant coatings, these coatings can quickly wear away in a short time when exposed to the harsh conditions of the oil and gas industry like offshore fracking sites.

Another issue that must be considered in these environments is exposure to diverse elements that can cause metal platforms to both rust and corrode. Things like salt water will only further the chance of equipment breakdowns and workplace injury.

Companies should invest in a well-planned strategy for workplace safety to combat these continuously dangerous situations.

Products like Sure-Foot’s anti-slip tapes are an excellent addition to surfaces that see heavy traffic or areas that are prone to accumulating moisture. For environments with extreme heat, cold, ocean exposure, increased foot traffic or other more strenuous factors, Master Stop EXTREME Tapes offers added adhesion and anti-slip safety.

Sure-Foot is also known for its fiberglass products, including step covers and walkway applications as well as product customization. Sure-Foot creates products that fit specifications for each customer, helping to increase and promote safety.

Vehicle Accidents

Accidents and incidents involving work vehicles continue to be a significant portion of workplace injury in the oil and gas industry.

For example, a vehicle could be driven to pipelines or pumping stations. Others could transport oil and gas. In addition, workers could be struck by work vehicles or machinery.

Many of these incidents can be attributed to carelessness due to employee fatigue. Long shifts, physically challenging work, and overexertion can lead to reduced awareness of workers.

Having safety signs, protective barriers and the proper warning labels on machinery can help to minimize these incidents. Adequate training for employees working with this equipment will make them more aware of the dangers they encounter in the workplace.

Injuries in the oil and gas industry will never be entirely preventable. But they can be limited with the proper safety planning, procedures, and safety products. Buy Sure-Foot to be sure!
