宝計機製作所 List of Products and Services

Electrical equipment used in hazardous locations, even if it is explosion-proof certified overseas such as IECEx or ATEX, cannot be used in Japan unless it has passed domestic explosion-proof testing. We have housed electrical devices such as highly demanded fiber optic sensors and PLC units in pressure-resistant explosion-proof boxes and obtained explosion-proof type certification (TIIS certification) to enable their use in hazardous locations. This allows for high flexibility in control, detection, communication, and printing in explosion-proof areas. Both hardware and software can be customized, so please feel free to contact us. "Featured Products" - Pressure-resistant explosion-proof PLC - Pressure-resistant explosion-proof batch counter - Pressure-resistant explosion-proof CC-Link unit - Pressure-resistant explosion-proof fiber optic sensor - Pressure-resistant explosion-proof multiplexer - Pressure-resistant explosion-proof serial/optical media converter - Pressure-resistant explosion-proof rotary connector - Internal pressure explosion-proof printer

We have housed the MELSEC Q series sequencer in a pressure-resistant explosion-proof box and obtained domestic explosion-proof certification. Electrical equipment used in hazardous locations, even if certified for explosion-proof use overseas such as IECEx or ATEX, cannot be used in Japan without undergoing domestic explosion-proof testing. This product has obtained domestic explosion-proof certification (TIIS certification) and can be safely used in explosion-proof areas. If the power supply ratings and other standards are met, it is possible to replace units from the Q series that are not standard. It is ideal for replacing conventional air purge panels and similar equipment. Since it can control external devices such as solenoid valves in hazardous locations, replacing the control unit of existing equipment with this product makes it easier to achieve explosion-proof compliance. Additionally, it can accept inputs from sensors and measuring instruments, allowing for easy construction of data collection systems in hazardous locations. When combined with our product, the "Pressure-Resistant Explosion-Proof CC-Link Remote I/O Expansion Unit," it is also possible to expand the number of signal I/O and analog I/O points, enabling the construction of data collection and signal monitoring systems in hazardous locations.

By housing the CC-Link remote I/O unit in a pressure-resistant explosion-proof box, it is possible to accommodate not only signal input/output expansion units but also analog input/output expansion units. Therefore, when combined with our pressure-resistant explosion-proof PLCs and pressure-resistant explosion-proof fiber optic sensors, it becomes easy to build monitoring and management systems for various measuring devices that can be completed solely within explosion-proof areas. ■ CC-Link I/O (input/output) expansion units with domestic explosion-proof certification that are not available from other companies ■ Changeable input/output point counts by swapping units

If the detection location is in an explosion-proof area and the amplifier cannot be placed nearby, there is a method to extend it by ordering a fiber unit, but there are the following disadvantages: 1. If the distance between the detection location and the amplifier is long, the light may attenuate, making accurate detection impossible. 2. There are labor and costs associated with wiring fragile photoelectric tubes over long distances. In such cases, please consider this product. This product houses the power supply and amplifier in a pressure-resistant explosion-proof box and has obtained domestic explosion-proof certification (TIIS), allowing for detection at close range without light attenuation. ■ This is a pressure-resistant explosion-proof type of fiber optic photoelectric sensor that could not be used in hazardous locations before. ■ It can be used for accurate presence detection and for detecting the rotation speed of rotating bodies in explosion-proof areas. ■ Up to three sets of amplifiers and fiber units can be housed. Additionally, by using our pressure-resistant explosion-proof PLC and pressure-resistant explosion-proof CC-Link remote expansion unit in conjunction, it is also possible to build a monitoring and management system that can operate entirely within hazardous locations.

Many cases exist where printers are installed in hazardous locations without obtaining explosion-proof certification, using methods such as air purging. However, this product is a pressure-resistant explosion-proof printer certified by domestic explosion-proof standards (TIIS). *Even products that have received explosion-proof certification overseas, such as IECEx or ATEX, cannot be used in Japan unless they have passed domestic explosion-proof testing. This printer is compatible not only with standard thermal roll paper but also with label-type roll paper and dust-free paper (clean paper). It can print weighing and measurement results on-site in explosion-proof areas, allowing for attachment to products or containers, making it ideal for identifying and ensuring traceability of shipped products. It can print not only text but also barcodes.

It can be connected to two standard flow meters in a hazardous area and allows for valve control. It also supports various types of temperature inputs such as temperature resistance thermometers and thermocouples. It features an easy-to-understand color LCD screen and a numeric keypad that facilitates batch settings. *Electrical equipment used in hazardous locations must have domestic explosion-proof certification in Japan, even if it has been certified for explosion-proof use overseas, such as IECEx or ATEX.

This product has obtained domestic explosion-proof certification (TIIS certification) and can be safely used in explosion-proof areas.

Since June 2016, risk assessment of chemical substances has become mandatory. Both the risk of explosion and ignition of equipment and machinery, as well as the potential adverse effects on workers' health, are subjects of risk assessment for businesses that manufacture and handle substances subject to the obligation to provide Safety Data Sheets (SDS). In response to this, our company offers products that comply with "explosion-proof structuralization of equipment." "List of Target Products" 1.
