MDM4901FL is dedicated to oxygen pressure measurement, filled with Fluorinated® oil. It specializes in gas pressure measurement in medical oxygen production equipment and oxygen storage tanks.
The differential pressure transmitter uses a piezoresistive sensor as the sensing element, silicon oil is filled between the die and two diaphragms. When the measured differential pressure is added on the two diaphragms, the pressure could be transferred onto the die through silicon oil. The sensor die connects with an amplifier circuit through wires, and uses the semiconductor's piezoresistive effect to transform the differential pressure signal into the electric signal. Since the signal output of the Wheatstone bridge on the die has a good linear relationship with the differential pressure, the differential pressure can be accurately measured. Industrial pressure sensors and transmitters are widely used in general and process control industries.

Micro Sensor is a world-renowned supplier of pressure sensors, transmitters, and flowmeters. Stable and reliable differential pressure measurement with high accuracy has become a brand recognized by global customers. There are so many applications of the differential pressure transmitter which makes it one of the most sought-after pressure transducers in the market.
The electrical output of a DP transmitter typically consists of a two-wire loop current or voltage signal.
The most common signal is the 4-20mA loop signal, where the transmitter generates a current that varies linearly with the measured pressure. The 4mA~20mADC signal is a standard analog signal that is proportional to the measured parameter. For example, if the sensor is measuring pressure, the output signal will be 4mA when the pressure is low and 20mA when the pressure is high. This current signal is usually fed to a controller or a data acquisition system where it can be converted into a pressure reading in engineering units.
Another output is the voltage signal. It ranges typically from 0-10V or 0-5V. This signal applies to the voltage inputs system. It is also used for requiring a higher resolution than the 4-20mA signal.
Different factors could affect the electrical output of a DP transmitter. So, it is important to ensure proper calibration and wiring for accurate and reliable measurements.
MicroSensor 4mA~20mA DC+HART provides both a standard analog signal and a digital signal. They allow for accurate and remote monitoring and configuration of the instruments.
Differential pressure transmitters apply to differential pressure measurement. They can also be used for level monitoring in closed tanks like level transmitters. Some common industries are listed below:
• Food and Pharmaceuticals
It plays a critical role in the quality and safety of food and pharmaceutical products by monitoring and controlling air flows in critical areas.
• Paper
Smart differential pressure transmitter conjunction with the computer control system measures pressure, flow, level, and other information in the production process, which greatly improves the production capacity of the equipment and reduces the product consumption and operating costs.
• HVAC
Differential pressure transmitters are commonly used in HVAC (Heating, Ventilation and Air Conditioning) systems to measure the difference in air pressure between two points in order to control the flow of air. They are typically used in applications such as:
1. Airflow measurement: Measure the airflow rate through ducts and HVAC systems.
2. Filter monitoring: Monitor the pressure drop across air filters, indicating when filters need to be changed.
3. Fan control: Control the speed of fans in HVAC systems by detecting changes in pressure that occur due to variation in air volume.
4. Balancing HVAC systems: Balance airflows in HVAC systems by measuring the differential pressure across dampers and valves.
5. Building pressurization: Maintain proper building pressure by regulating the airflow through doors and windows.
Of course, MicroSensor always delivers high stability DP measuring equipment for oil&gas, renewable energy, chemical&pertoleum and various industries. Our smart DP transmitters have a communication function, which can carry out two-way communication in the control room, transmitter site, and other places connected with the control loop to complete the setting, monitoring, and testing of parameters.
