Merit Sensor LP1400 Series

Merit Sensor LP1400 Series

The LP1400 uncompensated surface mountable pressure sensor series from Merit SensorTM 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 SensorTM 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 SensorTM products incorporate a proprietary Sentium® technology developed to provide a best-in-class operating temperature range and superior stability.
