Corporate History ／Corporate Information
It has been 50 years since the company was founded in 1970. I’ve loved playing with machines since I was a kid, and when I grew up I wanted to work in a factory that makes radios.
When I became a high school student, I was hooked on radio and bought a second-hand radio. I made transmitters and receivers with those parts, and communicated with domestic and foreign friends.
The experience at that time was the starting point of Unipulse technology.
Unipulse is a group of engineers.
We have wide technology capabilities such as electrical, electronic, wireless communication, machinery, measurement, materials, processing, control, and software. We have quickly created products that we wish we had and provided them to the market.
It has grown little by little while repeating it for decades.
Unipulse’s main products are load cells that measure weight and force, and sensors such as 3D force, force sensors, and torque meters.
The strain gauge used for the sensing part of the sensor is an in-house product based on our own know-how.
When developing a sensor, we will create the optimum strain gauge for that sensor too.
Therefore, Unipulse sensors are of very high quality.
Other products include weighing indicators, digital indicators, grip force sensors, displacement sensors, servo press controllers, etc. Our subsidiary ROBOTEC sells UNISERVO (Electric Torque Actuator), Moon Lifter (electric balancer), etc.
UNIPULSE CORPORATION will continue to introduce Japan’s first and world’s first products.
Please look forward to future new products.
President and Technical General Manager
We manufacture sensors such as loadcells and torque meters using our high-accuracy strain gauges. Our weighing indicators are widely used for auto-weighing machines such as Dosing machines, Filling machines, Packer scale, Hopper scale, Weigh bridges, Belt weighers and so on.
Rotating torque sensor is a newly developed hit-item. It is used to test rotational parts such as motors and engines.
Above mentioned Weighing indicators, Force indicators, Loadcells and Torque meters make up the majority of our sales.
Direct selling (without depending on trading companies) is our primary sales approach to be a close partner for our customers.
We also cover oversea market with sales office located in key countries, providing repair services and so on.
To supply and develop our new products, “UNISERVO (Electric Torque Actuator)” and “MoonLifter (Electric balancer)”, ROBOTEC Inc. was established.
|Strain gauge||An element that converts strain into electrical signal when a load is applied to its housing. It is used as a load detector for UNIPULSE’s Loadcell, Torque meter, Clamp meter and Pressure meter.|
|Rotating torque meter||Our torque sensors are used to detect torque applied to rotating shafts, mainly used for testing motors, engines, and other rotary components. Those are available in wide capacity ranges from 0.05Nm to 10000Nm, and we have drip-proof type as well.
In addition to a dedicated interface that can be connected to a computer via USB, there are also abundant peripheral devices such as an indicator that displays torque value, rotation speed, and power at the same time.
|Load cell||A range of 100g (1N) to 100ton (1MN) or more, and it is used by connecting to an indicator.|
|Weighing measurement||Weighing indicators are used with load cells to configure and control automated weighing systems like batching machines, weight fillers, packer scales, hopper scales, truck scales, constant-feeding belt scale, and so on.|
|Force measurement||Our digital indicators are used with load cells to monitor force applied in assembly operations like press-fitting and riveting for automated quality check (OK/not OK evaluation) of products.|
|Amplifiers/Peripherals||Amplifiers for load cells and other strain gauge type sensors, printer, recorders, etc….|
|Displacement measurement||Our displacement sensor product line includes capacitive type with 0.3nm resolution and non-contact fiber optic type with 3MHz bandwidth. Those are used for ultra-precision positioning, gap measurement, runout measurement, flatness measurement, vibration measurement, and more.|
|Vibration measurement||Our vibration monitors enable measurement of vibration magnitude, real-time analysis of frequency, pass/fail test of vibration level at specified frequency range, and so on.
Piezo type accelerometers or capacitive displacement sensors are used for this application.
|Torque Actuator||The first motion control actuator with a built-in torque control function.The torque is measured and feedback control is performed so that desired value is reached. (Made by ROBOTEC)|
Lifts up a workpiece of 10 to 1500 kg and move it with a light force.
It operates at AC100V or AC200V, and supports raising and lowering of the workpiece while constantly detecting the weight and position with the load sensor and servo motor. (Made by ROBOTEC)
