The Pressure Transducer, part number 77AH8994, is a differential analog sensor designed for PCB mounting. It operates with a maximum pressure of 1 psi and features a high-level amplified ratiometric output. The device is temperature compensated and requires a supply voltage of either 3.3 or 5.0 VDC. This transducer is suitable for various applications, including blocked filter detection, altitude and airspeed measurements, and medical instruments. It is constructed using a rugged ceramic material and includes barbed pressure ports that securely connect to 3/32,Äù ID tubing. The transducer is fully calibrated with a total error band of less than 1.0% over its compensated range, ensuring reliable performance. The MS4525 series also offers options for gel coating to enhance protection in humid or slightly corrosive environments. With a life expectancy of over 10 years and the ability to withstand mechanical shock and vibration, this pressure transducer is a robust choice for demanding applications.

MS4525
The MS4525 is a small, ceramic based, PCB mountedpressure transducer from TE Connectivity. The transducer isbuilt using our proprietary UltraStable process and the latestCMOS sensor conditioning circuitry to create a low cost, highperformance transducer designed to meet the strictestrequirement
The MS4525 is fully calibrated and temperature compensatedwith a total error band (TEB) of less than 1.0% over thecompensated range. The sensor operates from single supply ofeither 3.3 or 5.0VDC and requires a single external component forproper operation.
The rugged ceramic transducer is available in side port, top port,and manifold mount and can measure absolute, gage,differential, or compound pressure from 1 to 150psi. The 1/8”barbed pressure ports mate securely with 3/32” ID tubing.
