MMR920 Pressure Sensor for Liquid Handling Applications

https://nmbtc.com/landing/liquid-handling

The MMR920 micro pressure sensor with bi-directional measurement, robust construction, and high sensitivity makes it an ideal sensor for extraction and dispensing automated pipette robots. A miniaturized size of 7 mm x 7mm x 7.2mm size makes this sensor easy to integrate into a tight space. The MMR920 pressure cavity isolates pressure media to only the backside of the silicon pressure die keeping the electronics on the other side from being contaminated by harmful humidity. The MMR920 measures both positive and negative pressure with resolution as low as 1 Pascal.

The MMR920 utilizes proven microelectromechanical systems (MEMS) piezoresistive technology (PRT) sensor element with a 24-bit Analog Front End. Low pass filter is integrated allowing for smooth and high-resolution signal with the ability to detect fluid drop being dispensed from a pipette. The following GIF shows the sensor detecting drops of water leaving a 4 mm diameter tube after being extracted from a beaker. Pressure inside the tube rises incrementally as each fluid drop exits the tube.
