Merit Sensor Systems MEMS Sensing Elements Low Pressure Sensor J Series

The J Series from Merit Sensor Systems is designed for high-volume, low-pressure applications, offering a pressure range from 1 to 500 psi (0.07 to 34 bar; 7 to 3447 KPa). It features configurations for absolute, gage, differential, and vacuum pressure types, making it versatile for various uses. The sensor utilizes Merit Sensor's proprietary Sentium technology, which provides an operating temperature range of -40¬8C to 150¬8C and enhances stability. The J Series employs a piezoresistive Wheatstone bridge design, with a glass-to-silicon diaphragm bonding process, ensuring durability and reliability. The sensors are RoHS compliant and suitable for clean, dry air and non-corrosive gases. Typical output at 1 psi is approximately 40 mV, with a maximum excitation of 3 mA. The device also exhibits low non-linearity and hysteresis, contributing to its accuracy in pressure measurement. Engineers considering this product will find it beneficial for applications requiring precise low-pressure sensing, backed by the support of an established company in the sensor industry.
