SENSORS: All Sensors Corp.’s ½ inch H2O Full Scale Millivolt Output Pressure Sensor is the first ½ inch H2O Millivolt Output Pressure Sensor released to the market. Obtaining a ½ inch measurement from a millivolt device has become possible utilizing proprietary All Sensors’ CoBeam²TM Technology. The ½-inch device offers 2x the sensitivity of the 1 inch H2O device which provides higher signal to noise for the most demanding low-pressure applications. This millivolt pressure sensor offers accurate, low-pressure measurements at a more affordable price. The entire ½- to 30-inch H2O pressure sensor family is RoHS-compliant. The sensors are offered in a pc board mountable package with two pressure ports. Seven pressure ranges are available from ½ inch H2O full scale to 30 inch H2O full scale. They are available with a millivolt output proportional to either gage or differential pressure. Output offset errors are significantly reduced by electrical cross coupling compensation employed within the sensor.
