Learn 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.

How to Select Differential Pressure Transducers For Low-Differential, Critical Pressure Applications Part 2

System manufacturers are providing the highest quality, most reliable, and most energy efficient automobiles, airplanes, turbine and gas engines, and associated components ever produced. This is due in large part to the manufacturer's ever increasing demand for rigorous test and measurement of these products. 

For Low-Differential, Critical Pressure Applications Part 1 of 2

System manufacturers are providing the highest quality, most reliable, and most energy efficient automobiles, airplanes, turbine and gas engines, and associated components ever produced. This is due in large part to the manufacturer's ever increasing demand for rigorous test and measurement of these products. Differential pressure transducers are an integral part of that process for applications that demand reliability, repeatability, and high accuracy. This paper discusses how differential pressure transducers are used in critical pressure applications, two performance characteristics of a differential pressure transducer, and why they are important to consider when selecting a pressure transducer for low differential, critical pressure applications.

Current Switch Technology Comparison

When you have two choices of current switches to install on a variety of motors, which do you choose: a fixed set-point or an adjustable set-point switch? In order to compare fixed and adjustable, safety, inventory, and installation time will be examined to find the best switch for any application.

There are many risks associated with unmonitored humidity levels in buildings. The most significant of which is the health risks posed to the building’s occupants. Sick Building Syndrome can severely affect occupants’ comfort and productivity, but more alarming are some of the respiratory and other health ailments which can arise from unmonitored humidity levels.

Why are industry leaders using remote sensors?

Wet-to-wet differential pressure transducers have undergone several significant design and technological improvements recently. The most dramatic of which is the ability to install these units with remote sensors, rather than with traditional embedded sensing elements. A contractor can now easily install remote sensors directly into the pipes while an electrician makes electrical connections between the remote sensors and the transducer via cables or conduit. For industrial applications, contractors can order plumbing-ready cable versions with up to 30 feet of cable. When the local electrical code requires conduit, typically for projects like schools or municipal buildings, contractors can order units in the conduit version.

There are a variety of current switches and current transducers currently available for use in HVAC applications. Each product provides different features and benefits for that particular job. This post reviews two common types of current switches and a new technology that eliminates the risk of arc flash hazard during installation.

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.
