While sphygmo could be a problem, the manometer part should easily indicate that this has something to do with pressure. Sphygmo is based on a Greek word for pulse. Dating back to 1881, this blood pressure measuring instrument initially used a mercury column or manometer to indicate a person’s pulse in millimeters of mercury. However, […]
Extensometer for industrial, EN15000 and EN280 compliant off-highway vehicles
The VPG Transducers brand of Vishay Precision Group Inc. announced the global market introduction of its Model 182 extensometer, a specialty high-performance strain gage-based force sensor, expressly designed for industrial, EN15000 and EN280 compliant off-highway vehicle and equipment safety applications. The Model 182 extensometer accurately measures deformation, or changes in the length of a solid […]
What’s new in blood pressure monitoring?
Using the same type of technology employed in upper arm blood pressure measurements, the MOCACuff makes it easy for a person to automatically take their own blood pressure and pulse. The cuff displays systolic pressure above the diastolic pressure as well as the wearer’s pulse rate.
How can multiple sensor measurements be used to improve air quality ?
At CES 2017, Vincent Maxime, Product Manager from Enerbee describes how the use of airflow, temperature, humidity, CO2, volatile organic compounds (VOCs) and pressure measurements with the Bluetooth connectivity of the Enerbee Smart Vent can provide a visual indication of the healthy or unhealthy status of various rooms in your home.
Customized transducer for differential pressure applications
The UTD20 is a customized transducer that features a piezo-resistive silicon sensor for differential pressure applications. Outputs are voltage or UART digital. Measuring ranges from 0 to 1.5 bar–the measuring range and zero set point can be set. Accuracy is < ±0.5 % of the nominal range (total performance) and temperature range is from -40 to 85° C. Other features include: • Sensor preconfigured […]
New EK-P4 Evaluation Kit with Flow Element
Sensirion presents the advanced EK-P4 evaluation kit, which simplifies the evaluation of Sensirion’s differential pressure sensors even further. The kit combines all the features required for test measurement, including a flow element, so first measurements can be made cost-effectively and exceptionally quickly. The evaluation kit consists of a USB stick connected to a PCB on […]
Programming Pressure Switches
If a specific pressure point is critical for safe system operation, a pressure switch can make monitoring pressure rather straightforward. For its electronic pressure switches, Suco Technologies now offers a programmable device called the PPD05. With the kit, the user can program the upper and lower set point, set the time delay between the set […]
Using pressure sensors to make other measurements
by Randy Frank, Contributing Editor Many applications use pressure sensor measurements to calculate other key parameters such as flow, altitude, water column height, fluid depth, weight and more. In industrial applications, the most common use of pressure sensors to calculate another parameter is flow. In fluid flow applications, several factors determine the pressure drop that […]
High-res pressure sensor measures over 0.5 to 60-in. H2O range
A new low-pressure sensor called the DLHR Series works over lower pressure ranges of 0.5 to 60 in. H2O, an improvement over previous devices. Developed by All Sensors Corp., the DLHR Series is said to provide higher resolution than any other fully compensated low-pressure sensor currently available on the market. All error compensation takes place […]
Options for Pressure Switches
Similar to many applications, when a pressure sensing switch is required, there can be several factors that determine if a particular switch meets all the required design criteria. The right pressure range, environmental ruggedness and long life could be initial requirements. In some instances, something as seemingly simple as the connector can be a knockout […]
