This is SEGMENsensor: industrial sensors, built and tested on the production line. From laser welding to signal checks, every sensor is tested before it ships. Six product lines: magnetostrictive, liquid level, proximity, pressure, LVDT and ultrasonic flow. SEGMENsensor is the brand of SEGMEN (Shenzhen) Industrial Development, founded in Shenzhen in 2019. Our engineering team has 20+ years of sensor experience. Magnetostrictive position sensors start with the electronics: boards are soldered by hand, then the head, cable and connector are assembled. Rods and flanges are laser-welded, and the return signal of each sensor is checked on an oscilloscope. On a linear test bench, the magnet travels along the rod while software checks the reading over the full stroke. The nameplate is then laser-marked. Strokes run from 25 to 8000 mm. For liquid level, float switch stems and floats are injection-moulded, and the reed switch inside is formed and trimmed automatically. Each stem is filled and sealed, then every switch runs on a multi-station test rig as the floats move up and down. Sealed stainless steel assemblies are pressurised and held under water to check for leaks. Proximity switches are built on automatic assembly machines, where each sensing element is positioned and fitted. They are aged in a high-temperature test chamber, and dedicated test stations check the switching function and output of every sensor. Clamp-on ultrasonic flow meters are run on a water flow test line, with stainless steel tanks and pipe runs of several sizes. Fixed and compact meters are mounted on the line, and their readings are checked with water flowing through the pipe. In the field, the transducers clamp onto the outside of the pipe: no pipe cutting and no shutdown. Pressure transmitters, pressure switches and LVDT displacement sensors complete our core range. Working with us is simple: OEM volume supply, samples in 5–7 working days, production lead time confirmed with the quotation, and a reply within 24 hours. SEGMENsensor.

Proximity switches on the production line, from sensing element to final test. Reed sensing elements are fed into automatic assembly machines. Each element is positioned, formed and fitted automatically, one after another. Finished switches are aged in a high-temperature test chamber. Dedicated test stations then check the switching function and the output of every sensor. The readings on each station are checked before the sensors are packed.

Magnetostrictive position sensors: testing, calibration and marking. Electronics boards are aged on burn-in racks before assembly. Each sensor is then wired up for testing. The return signal is checked on an oscilloscope. On a linear test bench, the magnet moves along the rod, and the output is calibrated against its position. Calibration values are set and recorded in software. Finally, each nameplate is laser-marked with the model and the company details. Every sensor tested · OEM volume supply.

Our Story

From a Shenzhen Workshop to a Global Sensor Supplier

SEGMENsensor — operated by SEGMEN (Shenzhen) Industrial Development Co., Ltd. — was founded in 2019 by a team of measurement engineers who saw a gap in the market: precision industrial sensors that met international standards but could be ordered with the flexibility and speed that OEM manufacturers needed.

What began as a specialist manufacturer of liquid level sensors in Shenzhen has grown into a full-line industrial sensor company with six product lines — including proximity sensors, LVDT displacement sensors, magnetostrictive sensors, pressure transmitters, and ultrasonic flow meters — serving clients in oil & gas, semiconductor, chemical, and water treatment industries across more than 30 countries. Every sensor is designed, tested, and shipped from our own ISO 9001-certified facility.

Our technical content is written by the SEGMENsensor engineering team. Some drafts and translations are prepared with AI assistance, and every page is reviewed by our engineers before publishing. Specifications come from our datasheets.
