The 1865-07G-LDN is a pressure sensor and transducer from Omegadyne, which is used for the monitoring of dynamic pressure in low pressure vacuums and high pressure liquids. This sensor is designed for the measurement of pressures ranging from 0-50kPa on one side and 0-7kPa on the other side. It utilizes a hermetically sealed, low-noise amplifier to provide reliable and repeatable results with minimal power consumption.The 1865-07G-LDN pressure transducer is designed for use in a range of applications, including aerospace, medical, industrial, and automotive. In aerospace applications, it can be used as an on-board sensor for the measurement of environmental pressure during flight. In medical applications, the 1865-07G-LDN can be used to monitor and control pneumatically actuated systems for hospital beds, surgical tables, and respiratory assist devices. In industrial applications, it has been used in HVAC, water systems, air handling, and pneumatic control systems. Finally, in automotive applications, it has been used in brake systems for stability and performance monitoring.

The 1865-07G-LDN pressure sensor and transducer utilizes a MEMS-based, high fidelity piezoelectric technology to convert pressure signals into electrical signals. The physical measuring element is a diaphragm made from thin layers of ceramic and metal film. When the diaphragm is exposed to an externally applied pressure, it deforms slightly and this deformation is detected by the sensor as a voltage signal. This voltage is proportional to the amount of external pressure applied.

The output of the sensor is an amplified voltage which is proportional to the applied pressure. This voltage is then fed to a signal-conditioning circuit which provides adjustable low-pass filtering. This low-pass filtering ensures that high frequency noise is filtered out while the useful signal is passed through for further processing. The signal is then demodulated and digitizes in order to eliminate any signal offsets and errors. Finally, the output signal is fed to a controller or display device for further processing.

The 1865-07G-LDN pressure transducer provides reliable and repeatable results with minimum power consumption. It offers high linearity and temperature stability with an overall accuracy of ±1.2% FS (full-scale) over a temperature range of -40°C to +85°C. It also features excellent noise isolation with minimal power-supply ripple and is capable of operating at temperatures beyond this range with no additional circuitry. The 1865-07G-LDN is ideal for both dynamic pressure monitoring and low-pressure measurement applications, and its MEMS-based design offers low power consumption and accurate measurements.
