About

Established in 2002, Sing Long Technology is a Hong Kong Cantonese based manufacturer of
Pressure & Temperature Transducer, Transmitters, Gauges, Sensor Chips and other industrial sensors.

For over 15 years, we have been providing reliable customized OEM products for our clients to meet the demands of their applications. That’s to say, we can design and build a whole new product that satisfies the given requirements.

We operate with an emphasis on vertical integration, with engineering, manufacturing, assembly, functional testing handled by us.
We have developed a series of proprietary technologies for Gauge Wafer Design, Wafer Cutting and Wafer Separation, so that we can produce our own piezoresistive silicon strain gauges for our sensors, which can be as thin as 0.005mm. Gauges are sealed on the diaphragms at high temperature to secure the stability.

We are friendly and straightforward, please feel free to contact us if you have any questions.
