Honeywell 142PC05G MEMS Pressure Sensor Guide
The Honeywell 142PC05G MEMS pressure sensor is a compact board-mount device built for accurate low-pressure measurement in applications where vented gauge pressure sensing is required. As a Honeywell 142PC05G pressure sensor, it offers a practical mix of analog output, stable construction, and conditioned signal performance for engineering teams that need dependable readings without overcomplicating the circuit design.
Understanding the Honeywell 142PC05G Pressure Sensor
The Honeywell 142PC05G MEMS pressure sensor is part of Honeywell’s 140PC family. Unlike a differential model, this version is built as a vented gauge pressure sensor, meaning it measures pressure relative to ambient atmospheric pressure. That makes it useful in systems where the concern is how much pressure exists above or below the surrounding environment.
Because of that measurement style, the Honeywell 142PC05G pressure sensor can be relevant in pneumatic monitoring, gas handling, airflow control, and instrumentation designs where local atmospheric reference is important for system interpretation.
Technical Highlights
The Honeywell 142PC05G vented gauge pressure sensor has an operating pressure rating of 5 PSI (34.47 kPa). It runs from a 7 V to 16 V supply and provides an analog output between 1 V and 6 V. Accuracy is typically stated as ±1.5%. The unit uses a male 0.2 inch tube port, a through-hole 3-SIP module package, PC pin termination, and an operating temperature window of -40°C to 85°C. Maximum pressure is listed at 20 PSI.
Why the Honeywell 142PC05G Is Useful
A Honeywell 142PC05G pressure sensor is especially valuable when designers need low-pressure gauge readings with straightforward analog interfacing. In many embedded systems, raw sensing is only part of the challenge. The ability to capture a conditioned, amplified output can make firmware development, ADC scaling, and control-loop tuning far more manageable.
The Honeywell 142PC05G MEMS pressure sensor also works well in compact assemblies where board space and tubing layout must stay simple. Since it references ambient pressure, it can be a logical fit for systems that measure line pressure, enclosure pressure trends, or controlled pneumatic output against local atmosphere.
Integration Notes
When integrating the 142PC05G pressure sensor, teams should pay attention to tubing stability, media compatibility, electrical noise, and expected pressure spikes. Good mechanical routing and clean analog grounding often make a visible difference in signal quality, especially in compact instrumentation platforms.
Overall, the Honeywell 142PC05G vented gauge pressure sensor is a technically balanced option for low-pressure board-mount applications that need reliable analog behavior and a familiar mechanical format.
