Earth Checker

Earth Checker

Since it has an F-shaped relay design, it can be installed easily in a space-saving manner! It forms an alarm contact when it detects insulation failure.

We handle the "Earth Checker," which helps prevent failures by continuously monitoring the insulation resistance between the ground and the signal power supply and level crossing power supply as monitoring lines. The alarm contact configuration operation timing can correspond to each of the level crossing failure detectors N1, centralized automatic reset field devices, and electronic level crossing failure detectors. We conduct development design and manufacturing (prototype mass production) utilizing the technology of selecting LEDs and circuit board layout cultivated through railway signal and display devices. If you have requests like "I want an alarm like this" or "Can you make something like this with LEDs?" we are here to help, so please feel free to contact us. 【Features】 ■ When the insulation resistance of the monitoring line decreases and insulation failure is detected, an alarm contact is configured. ■ The F-type relay shape allows for space-saving and easy installation (the 5-circuit type is A-type relay shape). ■ The alarm contact configuration operation timing corresponds to each of the level crossing failure detectors N1, centralized automatic reset field devices, and electronic level crossing failure detectors. *For more details, please download the PDF or feel free to contact us.

Earth Checker (with fault detection function)

Earth Checker (with fault detection function)

Capable of storing insulation resistance values during normal monitoring, earth detection, and earth recovery.

This product is an "Earth Checker" that helps prevent failures by continuously monitoring the insulation resistance between the ground and the signal power and level crossing power supply lines. It has a built-in fault detection function that constantly monitors the integrity of the internal circuit and outputs self-failure information when an anomaly is detected. This reduces the risk of overlooking abnormalities in the line due to equipment failures. Our company conducts development design and manufacturing (prototyping and mass production) utilizing the technology of LED selection and circuit board layout cultivated through our experience with railway signal and display devices. We can solve your problems such as "I want a warning device like this" or "Can you make something like this with LEDs?" so please feel free to contact us. 【Features】 ■ It can store insulation resistance values during normal monitoring, ground detection, and ground recovery, and this stored data can be read using dedicated software. ■ Its F-shaped relay design allows for space-saving and easy installation. *For more details, please download the PDF or feel free to contact us.

FLC-103: Oxygen Flow Meter Checker

FLC-103: Oxygen Flow Meter Checker

Flow measurement and diagnosis of oxygen flow meters.

Oxygen flow meters are used almost daily in medical institutions, but in the case of flow-type meters, their accuracy decreases over time due to wear of the float and deterioration of seals, among other structural issues. Additionally, with dial-type meters, it is unclear whether the set amount of oxygen is actually being delivered, as there may be discrepancies between the dial reading and the actual oxygen flow due to damage from impacts or aging. For these reasons, oxygen flow meters require regular inspections. However, when medical institutions attempt to verify the accuracy of their oxygen flow meters, they need various equipment (such as pressure regulators, tubes, filters, flow meters, etc.), which makes the inspection process inefficient. Moreover, depending on the size of the institution, they may possess hundreds of these devices, making self-inspection challenging. The oxygen flow meter checker is a product that consolidates the necessary equipment for inspecting oxygen flow meters into a compact form. It is the ideal product for those considering checking their oxygen flow meters. We also offer demo units for loan. Please feel free to contact us.
