Why Do HVAC Systems Need Pressure Sensors?

With the growing requirements of building maintenance, HVAC systems are no longer able to meet demand operating alone. Whether it is a commercial, retail or industrial building, pressure sensors play a significant role in monitoring the building for occupants’ safety and comfort. When integrated with pressure technology, HVAC systems can operate at optimum levels as well as improve building maintenance. Three ways this can be done are:

What are the setbacks of an oil-filled sensor vs. non-oil filled?

In the pressure sensing industry there are many different sensor technologies, but all sensors can be broken down into two classifications; oil-filled, non-oil filled. An oil-filled sensor refers to a sensor that uses oil as a transfer medium between a diaphragm and the sensing element. Oil-filled sensors appeal to many manufacturing applications due to its material compatibility, low cost, and ease of implementation. Although these sensors are becoming a standard, there are several drawbacks to selecting an oil-filled sensor over a non-oil filled sensor.

Energy Savings Strategies For Operating Rooms

Operating Rooms consume a great deal of energy, considering the high airflow requirements needed, bright lighting, and significant plug load from patient care equipment. There are, however, strategies to conserve energy and still meet the stringent safety requirements of maintaining positive room pressure. Two conditions need to be met to enable OR energy savings. The first is a method to trigger occupied and unoccupied states. And the second is to act on that state change to setback both temperature and airflow.

Why Invest In Tenant Billing?

The goal of every residential and commercial building owner is to attract tenants and be profitable in the market. So what does tenant billing have to do with that? Tenant billing is an opportunity for building owners to understand where their energy is being used so they can charge tenants according to actual usage. Although it may seem like a lot of effort to implement submetering and to hold each individual accountable for their energy usage, tenant billing is a great investment for the following reasons:

What is the difference between BACnet, Modbus and LonWorks?

Until recently, there was no standard industry network protocol for building automation, and users had to choose between many different systems from different manufacturers. Proprietary communications were a result of no off-the shelf communication solution. Today, we have reached a place where there are three interoperable standard network protocols to choose from; BACnet, LonWorks and Modbus. All three are widely used, and according to a Building Operating Management survey in 2011, 62% of respondents had at least one BACnet application; for LonWorks the percentage was 40%, while for Modbus the number was 30%.
