½ inH2O mV Output Pressure Sensor

 

All Sensors Corporation of Morgan Hill, California has announced the release of a ½ inH2O Full Scale Millivolt Output Pressure Sensor. This announcement marks the first ½ inH2O Millivolt Output Pressure Sensor released to the market. Obtaining a ½ inch measurement from a millivolt device has become possible utilizing proprietary All Sensors’ CoBeam2™ Technology. The ½ inch device is an addition to the existing family of 1 to 30 inH2O Millivolt Output Pressure Sensors. The ½ inch device offers 2x the sensitivity of the 1 inH2O device which provides higher signal to noise for the most demanding low pressure applications. For the first time customers can now obtain ½ inch pressure measurements from a millivolt output device. This pressure range has traditionally only been available as an amplified device. This millivolt pressure sensor offers accurate, low pressure measurements at a more affordable price point ...

New Applications Opened up by Non-contact Angle Sensors

 

Non-contact rotary sensors are based on a magnetic, contactless sensor principle. They are accordingly not only free of wear and extremely robust in withstanding external influences, but demonstrate impressive long life, precision and resolution. They are available both as standard components and as customer-specific designs and, depending on the version, have tolerances of several millimetres in terms of axial offsets. They also boast convincing performance features, such as maximum 14-bit resolution and 10-bit precision at a linearity of 0.3 % ...

China Offering Bold Incentives for Sensor Companies

 

The global sensor industry could get a boost from a major new initiative recently announced in Wuxi, China by Premier Wen Jiabao. According to Steven Yang of WXICC, the Chinese government is determined to “spare no effort to develop the sensor industry” and has established this program to attract foreign and domestic sensor companies to Wuxi in Jiangsu province. Wuxi will invest over US $ 500 million to develop infrastructures, services, and subsidies for sensor companies, including a new 20 km2 “Sensor Park”. Wuxi is already home to 53 sensor companies, including MEMSIC ...
