Process Sensors And Their Role In Industrial Environments

Just as technical advancements have made our life easier and more comfortable, they have also had a positive and impressive impact in our working environment. Business organizations rely on computers and machines to satisfy their customers' expectations all year round and all day round and in almost every case to ensure high levels of productivity.

Industries and factories also require technical devices to help them perform at their best level, keep up with their clients' expectations and comply with the industry standards. Thus, industries and factories many a time rely on process sensors to make sure that the products being manufactured are being produced within the acceptable standards.

There are different process sensors available in the market. Some of them are specific to some industries while others can be shared by many. Two of the most popular ones are humidity sensors and temperature analyzers. We are going to deal with both of them in this article as they are quite generic and they are widely used in several industries.

HUMIDITY SENSORS

Humidity sensors are also popularly referred to as moisture analyzers or hygrometers. They are highly sophisticated instruments that allow factory owners and operators make sure that the product being manufactured is not exposed to the wrong levels of humidity and that it is being produced in an environment that has the right content of moisture. Believe it or not, this is quite a serious issue that has to be handled with accuracy and care. There are many products that can be ruined if they are exposed to more wetness than what they really need. For instance, if potato chips are packed wet they will taste sour when we eat them and coffee beans may smell sour and rotten if they are packed when they are not well dried enough. The wood industry also needs moisture analyzers: wood has to be dry enough to be able to cut it into pieces but wet enough to remain flexible. Industries use different hygrometers along the manufacturing process to keep close track of the humidity conditions in the environment.

TEMPERATURE METERS

Temperature meters are usually called thermometers and, as their name suggests, they are used to measure the temperature present in the manufacturing environment. They play an essential role in the chemical industry as chemical compounds cannot be exposed to dramatic changes in temperature or to very high or low temperatures under the risk of losing their properties.

Applications of Switchable Power Metering in Varying Environments

Remote managed PDUs, offered by PDUs Direct and referred to as Switched PDUs, are industrial grade power strips with network and serial connection ports. Through these communications ports, users are able to monitor power draw and environmental conditions, control the outlets (rebooting or turning outlets on/off), and receive alert notifications if user defined thresholds for amperage, temperature or humidity are breached. Other Switched PDU features include: programmable power up sequencing, which lets the administrator define delays between outlets to allow network equipment to connect before other equipment begins the start up process; grouping of outlets, for single command control of equipment with multiple power supplies; definable user access ensures users only see the sections they have been given access to and change conditions based on their access level ("on only", "reboot only", etc.); and with the addition of the linked expansion units, users may control multiple circuits from a single interface when practicing power redundancy.

Switched Rack PDUs were originally designed and used by large data centers as a means to reboot unresponsive servers quickly without sending techs into the racks. As co-location facilities arose they became more popular, giving the offsite network manager greater control of their equipment. The offsite teams could monitor their power consumption and environmental conditions in real time and quickly cycle their devices without traveling to the colo or paying site fees to have it done for them. Quality of life improved, as well, on call personnel no longer had to travel to the servers during off hours simply to reboot a server. It could all be controlled from their laptop or home computer.

School districts, university campuses, and other decentralized networks also adopted the Switched PDUs. With smaller network configurations, servers and other communications equipment spread out through many locations, the Switched PDUs allow a single operator to service and manage the entire network from a single location. No longer were service techs dispatched to simply reboot equipment. Over 80% of equipment errors were resolved by simply rebooting the device. By giving a single operator the ability to complete that task remotely, switched PDUs save considerable time, effort, and money.

Other industries are finding new applications for this type of remote power management every day. Broadcasting companies are using these Switched PDUs for their remote transmission sites, reducing time off air. Airlines use them to reset their self check-in terminals, keeping travelers moving through the process quicker and with fewer agents. Retailers, as well, find them useful to keep point of sale kiosks up and running.

Companies today must find new ways to stay competitive. New technologies are pivotal to providing that edge, improving productivity, and reducing costs. More new technology solutions are being introduced every day, but they are only solutions if they work correctly. Switched Rack PDUs provide one way to improve service levels, ensure network solutions remain operational, and save money.
