After reviewing the top 5 product considerations (pressure, media, temperature, and environment) in which the pressure transducer will be installed, it’s time to look at transducer construction, circuit design and the pressure transducer manufacturer's supply chain.

New Technology Eliminates Arc Flash Hazard
Pre-configuration of current switches can help eliminate arc flash danger and enable faster installation
Current switches, also known as current sensors, are used to monitor the operation of motors, pumps, fans, compressors, lights, and other equipment. Two common types of current switches currently available are fixed point and adjustable set point switches. Fixed current switches are designed with a single pre-determined set point and are beneficial because they are installed on cold circuits requiring no adjustment.

How to Select Multi-Range Pressure Sensors
When selecting multi-range pressure sensors, there are certain things to be cautious of. Often a "one size fits all" pressure transducer is chosen for expected cost savings and inventory control; however this decision turns out to be a bad idea. Issues arise with inaccuracy and poor stability on low range applications where the range output adjustment is simply pushed too far.

Application Note: Liquid Level Measurement
Liquid Level
The pressure measured at the bottom of a liquid filled tank is proportional to both the height (head) and density of the liquid. For best results the pressure should be sensed by a pressure transmitter mounted at the lowest point possible on the tank, as shown in Figure 1.
Openings Doors in the Operating Room
Recently, a major Boston-area hospital sought to resolve a problem in its operating rooms (OR). Nurses were complaining about how difficult it was to open the doors to the facility’s 23 operating rooms, 5 of which had just been built. They couldn’t understand why they had to pull so hard to open the doors. A veteran hospital HVAC engineering and design consultant did some investigating and recognized the problem of airborne lint on the sensors controlling OR pressurization.

How to Monitor Multiple Critical Spaces from One Location
The "central command station" of each floor in a hospital (aka the central nurse's station) plays a critical role in the proper operation of OR suites, isolation wards, and other critical spaces where room condition is crucial. Floor nurses and circulating nurses are tasked with monitoring multiple rooms in their wing, which requires them to physically check each room's condition via the room's condition monitoring device.
On the heels of an economic crisis, the President of the United States signed the American Recovery & Reinvestment Act (ARRA) in 2009 with the goal of:

What applications are suitable for capacitive pressure transducers?
Capacitive pressure transducers have earned a reputation for consistently high accuracy and unmatched long-term stability. These sensors find broad application in areas where characteristics rate from important to vital. A few of these include:
