A pressure sensor, which converts pressure signals into electrical signals, is the most prevalent type of sensor used in industrial applications. With the advent of Industry 4.0, the application of sensors has become increasingly widespread. The trend is moving towards high integration, miniaturization, and intelligence to meet the demands of complex operating conditions, confined spaces, and high-accuracy measurements. Micro Sensor has developed highly integrated, standardized signal output products in response to these trends. The company has optimized the use of the 288 series sensor die as the basis, and customizes different sizes based on user requirements, with the smallest diameter of Φ9mm.
MPM288DI I²C Pressure Sensor
Features
| ● Range: -1bar… 0~0bar…35bar ● Dual 24-bit ADC for pressure and temperature acquisition ● Standard I²C communication protocol ● Dedicated power consumption control pins ● Low-power consumption current: <100nA ● Accuracy: ±0.2%FS (±0.5%FS@0.35bar) |
Applications
Pressure and level measurement, smart pressure gauge, IoT
Conditions
MPM288DI pressure sensor is a typical application in portable Doppler ultrasonic flow meters, which are primarily used in open channel irrigation, municipal sewer pipelines, and hydrological basins. In the planned pipelines or channels, the pressure sensor on the flow meter monitors the water depth, while the ultrasonic sensor measures the flow velocity, enabling the calculation of the volumetric flow rate.
MPM288SA Pressure Sensor
Feature
| ●Range:﹣1bar…0bar~ 0.35bar....700bar ●φ19mm standard outer diameter, high interchangeability ●Standard voltage, current output signal ●Wide power supply range: 24V DC (8V ~ 28V DC), 5V DC (5V±0.3V DC), 3.3V DC (3.3V±0.3V DC) ●Compensation temperature: 0~ 70℃ ●Accuracy: ±0.25%FS (±0.5%FS@0.35bar) |
Applications
Medical device, pressure transmitter, flowmeter matching
Conditions
The electrical proportional valve consists of two solenoid valves, a pressure sensor, and an electronic control circuit. Based on the received analog signal input, one solenoid valve controls the inlet flow, while the other controls the outlet flow. The pressure sensor measures the pressure and transmits this data to the electronic circuit, enabling accurate pressure proportional control. It is applicable to pressure acquisition and control equipment.
