We have started handling the Phase Angle Voltmeter 2250A manufactured by North Atlantic Industries (NAI).

NAI Corporation's phase angle voltmeter

Application: Measurement of phase angle voltage, harmonic distortion, and other AC signals, LVDT/RVDT, network waveform analysis. We highly recommend replacing all existing NAI PAV products, including models 2250, 2251, 225, 321, and 213C, with the 2250A. ■ Half the size and weight of other existing models, yet highly accurate ■ High-resolution touch panel ■ Maximum harmonic rejection ratio of 80dB ■ Short setup time, fully programmable ■ Equipped with Ethernet, USB, and IEEE-488 ■ Capable of LVDT/RVDT measurement ■ Independent panel connections at the front and rear ■ Compatible with all existing NAI PVA products ■ 6VA internal reference power supply (optional) ◎ For more details, please refer to the PDF document or feel free to contact us.

Next-generation synchronous resolver signal generator. Suitable for the development of hybrid systems.

Compared to the old model 5330, a model with 2 channels is now available, and the range of L-L output, frequency, and rotation speed has been significantly expanded. This allows for the development of devices using resolver sensors developed for hybrid systems, in addition to conventional aircraft and ships. An optional built-in reference power supply is also available.

• Signal Generator

First in the NA company! Adopts a high-resolution touchscreen. Improved visibility and operability compared to previous models.

The 8810A employs pioneering synchronous digital conversion technology. 【Features】 【1】By adopting DSP, it eliminates push-button switches, allowing all program settings to be made using a touchscreen or mouse. 【2】You can select and display one of three options for angles: 0-360°, ±180°, or degrees/minutes/seconds. A wide frequency range of 47Hz to 20KHz is supported as standard. 【3】It is possible to individually measure two completely independent signal input angles. Additionally, it can perform combined 1X angle measurements using two signal input angles of multi-speed synchronous resolver signals. 【4】An optional internal reference power supply of 1.2VA is available. The gear ratio for multi-speed is programmable between 2:1 and 255:1. ◎ For more detailed information, please refer to the catalog or contact us directly.

Metal cracks are one of the concerns in equipment maintenance operations. Repairs using conventional welding methods can alter the base material around the crack due to heat, leading to residual stress and deformation, which always carries the risk of "crack recurrence" or "secondary damage." Hinode Waterworks Equipment Co., Ltd.'s "Mechanical Stitching Method" is a new technique that allows for the repair of metal cracks without applying heat. By using special bolts and reinforcement plates, the crack is physically removed without affecting the base material with heat. Repairs can be performed even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized.

Metal cracks are one of the concerns in equipment maintenance operations. Conventional welding methods for repairs can change the base material around the crack due to heat, leading to residual stress and deformation, which always carries the risk of "crack recurrence" and "secondary damage." Hinode Waterworks Equipment Co., Ltd.'s "Mechanical Stitching Method" is a new technique that allows for metal crack repairs without applying heat. By using special bolts and reinforcement plates, the crack is physically removed without affecting the base material at all. Repairs can be made even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. For more details, please contact us or download the catalog.

● The production time for cast prototypes can be shortened! Since model making is not required, the production time for prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly producing sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! Different products, such as similar shapes or varying dimensions, can be molded at the same time in one molding process. This allows for the verification of multiple types in a short period.

We will be exhibiting at the "3rd SPEXA International Space Business Exhibition" held at Tokyo Big Sight from May 27 (Wednesday) to May 29 (Friday), 2026. At this exhibition, we will introduce our precision casting and MIM (Metal Injection Molding) technologies, which cater to high-performance and difficult-to-machine materials such as A7075 super duralumin, Inconel, and titanium. "We want to reduce material costs." "We want to lower the machining costs of difficult-to-machine materials." "We are looking for a manufacturer for small quantity parts." In response to these challenges, Castem offers component manufacturing solutions utilizing casting and MIM technologies. We can accommodate everything from small-scale prototypes to small-lot repeat production. Please feel free to consult with us at the venue. 【Exhibition Overview】 Exhibition: 3rd SPEXA International Space Business Exhibition Dates: May 27 (Wednesday) to May 29 (Friday), 2026, 10:00 AM to 5:00 PM Venue: Tokyo Big Sight, South Exhibition Hall S6-2 (3-11-1 Ariake, Koto-ku, Tokyo) URL: https://www.spexa.jp/tokyo/ja-jp.html
