Pressure Sensors and Transducers are instruments which measure and transmit pressure of various fluids such as air, water, oil, etc. One such device is the MLH500PSD01B, which can monitor the pressure in demanding applications. It is a digital output pressure transducer designed with a stainless steel body and an electrical connection.

Application Field

The MLH500PSD01B is highly suitable for industrial applications such as oil and gas exploration, and in medical instruments. It is suitable for low-pressure measuring, providing accurate readings over a wide range of pressures. Other than that, this pressure transducer is an excellent choice for monitoring liquid levels and air pressure in vehicles and machinery.

The sensor is also suitable for automotive applications where a reliable pressure reading is required. It can be used in off-highway vehicles, hydraulic and pneumatic systems, and engine management systems. The device is also suited for applications that require long-term and continuous operation at low pressure and for more heavily loaded machines.

Features of the MLH500PSD01B Pressure Transducer

The MLH500PSD01B comes equipped with a 10 V supply voltage, a Pololu-compatible interface, and an I2C communication that supports a wide range of digital bus speeds. In addition, the device features a digital temperature compensation circuit, a wide temperature range, low power consumption, and a high signal-to-noise ratio.

• It features a range of 0 to +500 PSD, with a high accuracy of ±0.5% FSS.
• It uses a OEM Digital Intelligent signal digitization unit, which improves accuracy and prevent errors from occurring.
• The device has a long-term stability and a wide operating temperature range of -30°C to 80°C (-22°F to 176°F).
• The pressure transducer is extremely compact, measuring at only 38 mm x 18 mm (1.5" x 0.7").

Working Principle

The MLH500PSD01B is a differential pressure sensor which uses a piezoresistive-based pressure cell as its sensing element. The cell is connected to two pressure ports in order to measure the difference in pressure between them. The pressure cell senses the pressure difference between the two ports and converts it to an electrical output. This output is then sent to the OEM digitization unit, where it is further processed and then sent back to the sensor. The pressure cell is a key component of this pressure transducer, as it is responsible for detecting the different levels of pressure.

The OEM digital unit is designed to detect pressure differences between the two ports with great accuracy and resolution. The digital output from the pressure transducer is sent to the unit, where it is processed and converted to a digital output that corresponds to the current pressure. The unit also monitors the input current and voltage and it provides temperature compensated digitization for improved accuracy in a wide range of temperatures.

The digital output from the OEM digital unit goes to an I2C bus and it is then sent to the MLH500PSD01B pressure transducer. This allows the device to be monitored and controlled from a remote location, enabling it to be used in a wide variety of applications.

Conclusion

The MLH500PSD01B is an advanced pressure transducer which can be used for a range of applications. Its stainless steel body and digital output make it suitable for measuring pressure in a wide range of applications, including oil and gas exploration, automotive and industrial systems, and medical instruments. Its features, such as low power consumption, a wide temperature range, and an I2C communication, make it an excellent choice for long-term operation at low pressure.
