Choosing an Industrial Pressure Transducer
Key specification decisions
- Range — pick a range where your normal operating pressure sits in the middle third; avoid oversizing (accuracy is % of full scale).
- Output — 4-20mA for PLC/SCADA and long runs; 0-10V for local controllers; RS485 for multi-drop digital bus.
- Media compatibility — 316L stainless handles water, oil, most hydraulic fluids; chemical media may need Hastelloy or ceramic diaphragm.
- Connection — G1/4 and 1/4" NPT are the most common; flush diaphragm for viscous or hygienic media.
- Accuracy — ±0.5% for general monitoring, ±0.25% standard, ±0.1% for test & calibration duty.
Typical applications
- Hydraulic systems — presses, injection molding machines, excavators: measure system and cylinder pressure continuously.
- Pumps & water supply — suction/discharge pressure monitoring, booster pump control, tank level via hydrostatic pressure.
- Compressors & pneumatics — receiver pressure, line monitoring, leak detection.
- Process industries — line and vessel pressure in chemical, food and pharmaceutical plants.
- OEM machinery — embedded pressure monitoring for machine builders and equipment manufacturers.

FAQ
Questions Buyers Ask
What is the difference between a pressure transducer and a pressure transmitter?
In practice the terms are used interchangeably in most industrial settings. Strictly, a transmitter includes signal conditioning and produces a standard output (4-20mA, 0-10V), while a transducer can mean the sensing element alone. Every PRESSUREPOINT model ships as a complete, ready-to-wire instrument with the output signal you specify.
Which output signal should I choose: 4-20mA or 0-10V?
4-20mA two-wire is the industrial standard — immune to voltage drop over long cable runs and supported by every PLC. Choose 0-10V for short runs and simple controllers, or RS485 Modbus when you need to daisy-chain many sensors on one bus.
What pressure ranges are available?
From vacuum (-1 bar) to 600 bar standard, with custom ranges in between. Common standards: 0-1, 0-6, 0-10, 0-16, 0-25, 0-40, 0-100, 0-250, 0-400, 0-600 bar. Tell us your working range and we confirm a model with the best accuracy within it.
Can you customise the process connection?
Yes — G1/4, G1/2, 1/4" NPT, 1/2" NPT, M20×1.5, M12×1.5, flush diaphragm and custom threads are available. Send your drawing or spec and we produce to it.
What is the typical lead time?
Standard models ship in 7-15 days. Custom OEM builds (range, connection, output, cable) typically 15-25 days after drawing confirmation. Small MOQ from 10 pcs for standard models.
