While many medical ventilation measurements are easily handled by a 0 to 500 Pa differential pressure sensor, some require a wider dynamic range. For these applications, Sensirion introduced the SDP2108-R sensor. Based on its SDP1108-R that covers a measurement range of 0 to 500 Pa, the SDP2108-R addresses a range of 0 to 3500 Pa.The […]

High Temperature Pressure Sensor Targets Gas Turbine Monitoring
Most pressure sensors are offered in plastic packages and operate in a maximum ambient temperature of 125°C or less. Monitoring the pressure of a gas turbine requires a totally different approach. IMI Sensors Series 176 pressure sensors use a stainless steel housing and piezoelectric sensing technology to tolerate the extreme heat environment (+986°F, +530°C) generated […]
Mold-Align® tools helps ensure precise mating at the parting line
Mold-Align® is a new tool from Sensor Products Inc. (Madison NJ USA) that helps improve yields and reduce defects in the injection molding process. It comes in rolls from which you cut a sheet of the amount you need and place between the mold halves. The paper instantaneously changes color to reveal how pressure is […]
Embedded Pressure Sensor Addresses Variable Air Volume (VAV) in Wireless System
Here is an interesting application of pressure sensors in a wireless environment. CAN2GO’s Variable Air Volume (VAV) building automation controller has an on-board pressure sensor and is capable of bidirectional communication with EnOcean and wired end-devices. EnOcean is rapidly becoming the defacto standard for wireless building automation. The controller features an embedded EnOcean transceiver and […]
How Pressure Sensors Can Help Your Golf Swing
Sensosolutions SensoGlove embeds four tiny pressure sensors into a golf glove to analyze the pressure that the golfer is exerting during his/her swing. Contrary to natural instinct, an excessively tight grip does not usually provide the expected results. To achieve the right amount of pressure, a target pressure level from 1-to-18 can be set and […]
Electro-Pneumatic Analog Circuit-Card Servo Pressure Transducers
Marsh Bellofram Type 3110 and Type 3120, a series of single- (3110) and double-loop (3120) electro-pneumatic analog circuit-card servo pressure transducers are designed for space-conscious, high-performance, economical air pressure monitoring applications. With a footprint of 2 x 2.8 inches (50.8 x 71.12 mm) and available analog monitor output ranges from 29” Hg to 600 psig, […]
Measuring Surface Contact and Pressure Distribution Between a Heat Sink and Its Source
Sensor Products Inc.’s Tactilus heat-sink analysis system uses a flexible sensor and hub to display heat sink data on a PC for heat-generating chips such as a CPU. Since it is flexible and only 0.015-in. thick (0.38 mm), the sensor can be placed between the CPU and heat sink without affecting the assembly. Data can […]
Endevco Absolute Pressure Transducer Addresses High-Sensitivity Applications
Meggitt Sensing Systems Endevco model 8530B is a high-sensitivity absolute pressure transducer in a compact 3.86-mm face diameter package. The active four-arm strain gage bridge in silicon design is offered in ranges of 200, 500 and 1000 psia with 300 mV full scale output and high resonant frequencies of 750 kHz (200 psia). In addition, […]
Sensirion SDP600 Differential Pressure Sensors Now Include Failsafe Versions
Already used successfully in medical and HVAC applications, the newest Sensirion differential pressure sensor models, SDP620, SDP621, SDP630 and SDP631, allow verification of the measured values. The failsafe sensors can be configured to provide special test patterns for error checking by an external microprocessor. With the right test pattern configurations, it is possible to measure […]
Measuring and Analyzing Engine Combustion Pressures
One of the more complex, yet increasing important pressure measurements is combustion pressure. For carmakers to meet emissions and fuel economy regulations, measuring the subtle variations in combustion pressure is critical. David R. Rogers has written a book specifically addressing the topic called, Engine Combustion: Pressure Measurement and Analysis. Published by SAE, the text is a comprehensive […]
