Flow, Current & Differential Pressure Sensors for IoT

Aceinna’s (formerly Memsic) flow and differential pressure sensors are designed to serve the need for mass flow and pressure sensing in multiple applications such as gas meters, process control, HVAC, medical, chemical, food and beverage, etc.

Aceinna is a spin-off of Memsic Inc. a world leader in MEMS sensor technology.

Aceinna’s patented thermal sensing technology offers many advantages over traditional solutions, including but not limited to: large dynamic range, high accuracy, excellent low flow sensitivity, low pressure drop, very low power consumption, no moving parts for long term reliability, and integrated CMOS circuitry.

Aceinna gas flow sensors include the MFC 2030,MCA1101-50-5 and MDP200 product families.

The MFC2030 gas flow sensor family is a highly configurable, bi-directional flow platform that is being offered in several variations, including 30 and 70 SLM flow ranges, and mechanical configurations including straight inlet, manifold, and PCB mount. The product family is designed for a wide variety of applications, ranging from industrial applications to medical devices.

The MDP200 differential pressure sensor is a highly accurate and stable pressure sensor, designed for industrial, HVAC, and medical applications. The sensor is offered in a +/- 500 Pa configuration with custom ranges available. The sensor is available in bard and manifold mount, with straight and angled connector pins.
