Supervisory Control and Data Acquisition Systems refer to remotely located systems that automatically collect data on electrical equipment for monitoring and control. The arrangements are designed to reduce the cost of having a person physically reading instruments and changing settings of operating controls in these remote areas.
It also allows for this monitoring/supervising multiple systems in one central location. These systems existed long before the computerization of cloud-based networks and SOC, security operation centers, for SCADA networks.
The First Hybrid Vehicle was a Mule Most of us haven't spent much time thinking or hearing about Hybrids until car manufacturers began bombarding us with advertising about new Hybrid vehicles. We associate Hybrid with the combination of traditional combustion engines and electrical power. The term has been around for a long time. Its definition as a noun in biology relates to the offspring of plants and animals. When was the last time you saw a mule? PTC Electric Heating is part of the modern hybrid technology. In a way, we are all Hybrids. Our...
There are 4 primary types of industrial drum heaters with each offering different characteristics and ease of operation. Depending on your application one may be more suitable than the others. Each of the following types is available for 5-gallon buckets to 55-gallon drums.
Drum heaters can melt or reduce the viscosities of materials such as soap, fats, varnishes, oils, foodstuffs, or others needing to be pumped or poured. Also called barrel heaters here are the 4 main types of industrial heaters for drums.
- Base Drum Heaters
- Blanket Drum Heaters
- Induction Drum Heaters
- Band Drum Heaters
What Do Tubular Heaters Power Ratings Mean?
Tubular heaters are resistant heaters encased in round tubes often shaped for specific applications. The tube’s materials and casing protect the electric resistive heating elements inside the heater from damage and direct contact with fluids or other materials.
The tubular element conducts heat effectively from the resistive elements to the air or other material surrounding the tubular casing.
This effective transfer of heat without air contacting the surface of the resistive wire allows the heating element to operate at a fixed power output without burning the resistive elements; as a result, no oxidation takes place, and the voltage and current are isolated the surface of the casing.
