Chairperson’s Message
Unipulse was established by a handful of young engineers including myself in 1970, with an aspiration to create unique products using our pulse (digital) circuit technologies.
From the very start, we have been specializing in stress measurement using strain gauge and force and weight measurement by load cell. Especially for weighing indicators, we were the pioneer in the world to commercialize them. Since then, with technology expertise we have developed a number of products such as; digital indicators which helps press-fitting and caulking etc. to be performed with optimal load; contactless capacitive displacement sensors, grip force checkers, clamping force checkers and rotating torque meters.
The rotating torque meter in particular has become the standard of shaft type torque measurement, and has been used at great deal of development and manufacturing sites.
In recent years, we have started in-house manufacturing of strain gauges, producing load cells and multi-axis sensors in our own facilities.
A new product UTF series, a flange type torque meter capable of measuring high-frequency torque fluctuation, comprises high safe overload and high torsional stiffness. This series is developed for testing of engines and motors.
Furthermore, we pour our efforts into the development and the sales of various robots such as a torque actuator UNISERVO and an intelligent assist balancer Moon Lifter etc.
Especially, the intelligent balancer can assist transferring heavy objects with operation feeling with human hands as one likes. This is achieved by force sensor and servo motor that constantly detect force and position. It has been receiving a favorable reception from many customers due to its excellent handleability never seen before.
Unipulse will continue it’s efforts to place the highest priority to R&D, and is committed to keep introducing the Japan’s first and the world’s first products.
We do hope you will give us further guidance and encouragement in the future.

Product category
| 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 0.05 N m to 10000 N m, 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 100 g (1 N) to 100 tons (1 M N) 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 0.3 nm resolution and non-contact fiber optic type with 3 MHz 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. |
| Electric Balancer |
Lifts up a workpiece of 0.1 kg to 2 tons and move it with a light force. It operates at AC 100 V or AC 200 V, and supports raising and lowering of the workpiece while constantly detecting the weight and position with the load sensor and servo motor. |
