The SSCMRRN006MDAA3 board mount pressure sensor with dual radial barbed differential, 3.3V is a micro-machined, silicon-on-insulator (SOI) based sensor that uses a signal conditioning ASIC to provide a precise, linear output signal. Key benefits of this sensor include its high accuracy, small size, low power consumption, and excellent repeatability. This sensor is primarily used in applications requiring differential pressure measurement such as HVAC systems, control valves, and process systems. This version of the sensor is available with a standard range of 0-21psi and is designed for surface mounting onto PCBs. The pressure sensors feature an internal micro-machined diaphragm which is sealed to the device using MEMS sealing technology. The pressure port is sealed by three radial barbed O-rings, ensuring liquid tight operation minimizing permeation and allowing for operation in harsh environments.
