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:

A common concern surrounding tank level measurement is selecting the right type of sensor technology. Selecting the proper sensor technology will ultimately be determined by the conditions within the tank. The first thing you need to determine is if your vented tank is above ground or buried in-ground. An above ground tank will typically have a process connection external near the bottom of the tank, providing easy access to the sensor. A tank that sits in-ground will typically have an access hatch, where you can install your tank level sensor. Hydrostatic (gauge), capacitance, resistive and ultrasonic sensors are most commonly used for more critical tank level applications. Although they all measure liquid level, they work in different ways.

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

hat: 2015 NCSL International Workshop & Symposium

When: July 19-23, 2015

Where: Grapevine, Texas

Exhibitors, speakers and attendees will gather for The National Conference of Standards Laboratories International Workshop & Symposium in just a few short weeks.  Taking place over 5 days, the abundance of programming will keep any participant busy for the whole event. This year, tutorial programs and technical programs will focus on Measurement Science and the Quality of Life.

Absolute Pressure — Pressure measured relative to full vacuum. Referred to as pounds per square inch absolute (PSIA).

Atmospheric Pressure — Pressure of the atmosphere at the earth’s surface NIST standard atmospheric pressure = 1.01325 bar.

BAR — Unit of pressure (or stress). 1 bar = 750.07 mm of mercury at 0°C, at 45°.

Look no further than the recent Ebola case in the US to understand that one of the greatest fears in the general population is the rapid spread of infectious disease. When infectious diseases such as Ebola and MERS make an appearance, they immediately become front page news and are featured by every media outlet across America. 

While there are many strategies employed to prevent these infectious diseases from becoming a
