Miniature Pressure Sensors
Miniature pressure sensors are compact OEM transducer modules designed to be embedded inside machinery, portable equipment and instrument sub-assemblies where space is limited. Body diameters from 12 mm keep the sensing element, signal conditioning and process connection in a light package, with 4-20mA, 0-10V, RS485 or mV output to suit your controller. PRESSUREPOINT builds these factory-direct with custom ranges from vacuum to 600 bar, standard G1/4, G1/8, NPT and M12 threads, and your choice of cable or connector termination. Typical applications include pneumatic controls, medical devices, hydraulic tools, compressors, robotics and test equipment where a standard-size transducer will not fit.

Designing a Miniature Sensor Into Your Product
Integration decisions
- Size vs performance — smaller bodies trade a little on mounting options, not on output or media compatibility; confirm thread size and overall length against your envelope.
- Output — mV output keeps cost and size down when your board does the conditioning; 4-20mA and RS485 simplify wiring and immunity in noisy machines.
- Mounting — G1/4 and G1/8 threads suit manifolds and valve blocks; M12×1.5 suits hydraulic tooling; confirm seal type for your port.
- Environment — choose IP rating and connector style for the operating environment; vibration, splash and washdown all affect termination choice.
- Calibration — factory-set range and zero points remove field adjustment from your production line and keep quality consistent.
Typical applications
- Pneumatic controls — manifold pressure and actuator monitoring in compact valve islands.
- Hydraulic tools — force and pressure feedback inside torque wrenches, pumps and portable power units.
- Medical & laboratory devices — gas and liquid pressure in analyzers, dialysis and infusion equipment.
- Compressors & pumps — embedded monitoring in packaged units where the controller lives beside the sensor.
- Robotics & automation — grip force and clamp pressure sensing in end effectors and tooling.

FAQ
Questions Buyers Ask
How small does a miniature pressure sensor get?
Body diameters from 12 mm are available depending on range and output. Compact OEM modules keep the sensing element, signal conditioning and process connection in a short, light package that fits into machine sub-assemblies and portable equipment.
Can a miniature sensor provide the same outputs as a full-size transducer?
Yes. 4-20mA, 0-10V and RS485 Modbus are available in small housings. For customer-conditioned designs we also supply mV-output variants where your electronics do the amplification.
What pressure ranges fit in a miniature package?
From vacuum (-1 bar) up to 600 bar depending on the model. Small ranges suit pneumatic controls and low-pressure monitoring; high ranges suit compact hydraulic tools. Send your working range and we will confirm a suitable build.
How do I integrate a miniature sensor into my product?
Choose the process thread (G1/4, G1/8, NPT, M12×1.5 and others), output signal and cable or connector termination. Custom ranges and calibration points are set at the factory so the sensor arrives matched to your application.
What is the minimum order quantity for OEM builds?
Standard models start from 10 pcs. Custom OEM builds (range, connection, output, cable) typically run 15-25 days after drawing confirmation, with quantity pricing discussed per project.
