About HMK-TECH
Precision Pressure Measurement Since 2006
We are a professional manufacturer of pressure measuring and controlling instruments, established in 2006 in Nanjing, China. For nearly two decades, we have been introducing internationally advanced production technology, precision equipment, and the strictest quality standards from leading European sensor manufacturers — applying them to design and produce proven pressure sensors, transmitters, and level measurement instruments for customers in over 100 countries.
Our Story
Our company was founded with a clear mission: to bridge the gap between European sensor precision and the growing global demand for reliable, cost-effective pressure measurement solutions.
From day one, we invested in importing the most advanced piezoresistive sensing elements, production processes, and quality control methodologies from Europe. Rather than simply reselling products, we built a complete R&D and manufacturing capability — enabling us to not only replicate proven sensor performance, but also to innovate and customize solutions for the unique challenges our customers face across diverse industries.
Today, our product portfolio spans six major categories with dozens of series and several hundred configurable variants. These instruments have been deployed in critical applications across aerospace, military defense, petroleum exploration, chemical processing, power generation, manufacturing automation, medical devices, pharmaceutical production, and food processing — proving their reliability in some of the world’s most demanding environments.

Our Core Capabilities
Advanced Sensing Technology
We utilize internationally advanced piezoresistive silicon sensing elements, combined with ceramic capacitive, sapphire (SOS — Silicon on Sapphire), and diffused silicon technologies. This multi-technology approach allows us to cover an exceptionally wide range of applications:
- Pressure ranges: 0.02 Pa vacuum to 100 MPa ultra-high pressure
- Accuracy: Up to ±0.1% FS (combined linearity, hysteresis, and repeatability)
- Temperature range: -40°C to +800°C (with sapphire/SOS technology)
- Long-term stability: ±0.1% FS per year
Precision Manufacturing
Our production facility is equipped with:
- Laser-trimmed resistance temperature compensation systems
- Automated multi-point pressure calibration stations
- Aging and pressure-cycling test chambers
- 100% factory testing and inspection before shipment
- NIST-traceable reference pressure standards
Every sensor undergoes a comprehensive manufacturing process including bonding, oil filling, diaphragm welding, sealing, pressure impact testing, aging, temperature compensation, resistance adjustment, and final inspection.
Custom Engineering & OEM/ODM
Our in-house R&D team can design, re-engineer, or modify any product to meet your specific application requirements:
- Custom pressure ranges — from ultra-low vacuum (Pa level) to ultra-high (100 MPa+)
- Custom output signals — 4–20 mA, 0–5 V, 0–10 V, RS485 Modbus, HART, IO-Link
- Custom process connections — NPT, BSP (G-thread), Metric, flange, tri-clamp, DIN 3852
- Custom wetted materials — 316L SS, Hastelloy C-276, Titanium, Monel, ceramic
- Custom housing, cable, connector, and branding
Typical OEM/ODM lead time: 7–15 working days from design confirmation to delivery.
