Uncompensated Output Surface Mount Pressure Sensor

The LP1400 uncompensated surface mountable pressure sensor series from Merit Sensor^TM suitable for ultra low pressure sensing applications. This pressure sensor series offers a low pressure range from 0.15psi to 1psi and a medium pressure range from 5psi to 30psi. The LP1400 series from Merit Sensor^TM is designed for clean, dry air and non corrosive gases, with an operating temperature range of −40°C to +85°C and an impedance of 5kΩ. Merit Sensor^TM products incorporate a proprietary Sentium® technology developed to provide a best-in-class operating temperature range and superior stability.
