A common issue that users see is that a new device is added to a network but is not communicating with the segment or has intermittent communication. Troubleshoot BACnet communication problems through the following steps:

Hospitals and outpatient facilities serve a critical need in global communities. They provide emergency care for the sick, but we also rely on them as a safe zone for treating communicable diseases and keeping the public safe. Pressurized rooms in these special buildings are designed to contain dangerous airborne contaminants, such as tuberculosis, aspergillus, and vaporized cough. When properly pressurized, these rooms protect the most vulnerable patients, and allow healthcare staff to safely treat highly infectious cond

Any design engineer must seriously consider the manufacturing environment when looking to select a pressure transducer for inclusion within a refrigeration chiller, pump, engine test equipment, or other machinery. The life of a pressure transducer is proportional to the system design and assembly process. 

The following steps clearly indicate the exact sequence to properly troubleshoot a Setra 2 wire, mil-amp circuit. You must work with the assumption that either the Setra product or the system & circuitry is bad.

Which method provides better accuracy?  Non-linearity as the End Point Method is the relationship of the calibration curve to a specified straight line through its endpoints (i.e. Zero and Full Scale). Best Fit Straight Line (BFSL) method is the relationship of the calibration curve to a calculated straight line that minimizes the error but does not pass through the end points. BFSL method effectively cuts the end point value in half.

Knowledge is power. This statement has been thrown around a lot, but it really holds true. Being aware and having insight can lead to being proactive instead of reactive. Knowing the facts about an issue can not just fix them but give lasting solutions. One issue that greatly impacts the majority of the world is energy usage. With resources being depleted every year, energy monitoring allows for consumption awareness on any kind of level.

This year's NCSL International Workshop and Symposium took place July 19^th through the 23^rd in Grapevine, TX, which brought together measurement industry professionals and thought leaders under one roof. The theme for the 2015 NCSL International Workshop & Symposium focused on “Measurement Science and the Quality of Life", which emphasized the role measurement science plays

When selecting a relative humidity (RH) sensor, there are many factors to keep in mind that can contribute to longer product life and a successful project.  Being aware of the environmental conditions where the sensor will be installed can help determine the correct product specification for the sensor. Every application has its own challenges and requirements. To ensure that you choose the correct RH sensor for your application, ask the following 10 questions:

One of the most vital processes within critical environments is the sterilization of medical tools and devices. Patient safety relies heavily on the efficiency and reliability of sterilization devices. Contaminants can become highly resistive to disinfection, which results in the need for high performance sterilization methods that will ensure sterile equipment. Three primary methods of medical sterilization occur from high temperature/pressure and chemical processes.

Using temperature stand-offs can replace expensive high temperature pressure sensors.

When selecting a pressure transducer for monitoring high temperature liquids or gases, be sure to note the operating temperature range of the transducer. This specification is included under environmental data on most manufacturers’ data sheets. The temperature compensated range specification of a transducer is the error introduced as temperature increases or decreases from 70°F. This thermal error affects both the span and zero setting of the transducers analog output and is generally listed as a percent of full scale per degree (% FS/°F). The static accuracy (accuracy at 70°F) of the pressure transducer plus the thermal error introduced by a high temperature pressure source is the total possible error for a specific high temperature pressure measurement
