Dust Concentration Meter "Dust Monitor" for Detecting Leaks and Tears in Bag Filters

Catch dust that cannot be visually confirmed! A dust concentration meter that ensures safety through continuous monitoring.

The dust monitor continuously measures the dust concentration in the exhaust gases on the secondary side of dust collectors and monitors changes in relative dust levels, outputting alarm contacts and analog signals in case of abnormalities. It detects the frictional static electricity of dust that comes into contact with or passes near the detection probe. It can be easily installed in existing setups and is useful for environmental measures. Additionally, it is equipped with a concentration correction function, allowing for output correction to the dust concentration obtained by JIS measurement methods by adding a correction factor to the detection signal. Changes in dust levels due to leaks or tears in bags can be monitored, and continuous concentration changes can be output at levels close to actual measurements, enabling trend management of dust collector performance to be monitored at values close to JIS measurement methods. Moreover, it has obtained domestic explosion-proof certification, making it usable in first and second category hazardous locations (zone 1.2). ● Domestic production ensures stable supply Maintenance only requires regular cleaning of the probe. ● Low cost with performance equivalent to optical methods Measurement range of 0 to 1000 mg/m³ with 9 range switches. Detectable particle size from 0.3 μm. ● No specialized knowledge required. Range setting and sensitivity adjustment can be easily made with a switch.

Belt Misalignment Detector "Belt Offset Switch"

It is possible to prevent damage to expensive conveyor belts and falling debris, thereby preventing disruptions in the transportation system caused by accidents!

The belt misalignment switch is a protective switch that detects misalignment and wandering of the belt conveyor, issuing alarm signals and emergency stop signals. It can be used to prevent damage to the belt edges and to avoid material spillage due to belt misalignment. The belt misalignment switch is essential for the safe operation of belt conveyors and is widely used in industries such as steel, cement, chemical, and thermal power plants. 【Features】 ● It is designed for outdoor use with an IP67 rating. ● The highly reliable micro switch uses maintenance-free ball bearings and a touch roller that can tilt up to 75°, ensuring a design with functional margin, so it operates reliably even in cases of abnormal belt misalignment and has a long lifespan. ● When the contacts operate, the touch roller does not reset until it returns more than 2° (hysteresis characteristic), preventing repeated opening and closing of the contacts during operation. Therefore, it can protect the belt conveyor with a simple control circuit. *For more details, please download the catalog or contact us.

Conveyor belt longitudinal tear detector "Belt Longitudinal Tear Detector"

We will detect vertical tearing accidents of conveyor belts early!

The belt longitudinal tear detector is a switch that instantly detects longitudinal tears in the belt caused by foreign objects penetrating the belt at the chute drop-off point of the belt conveyor and outputs an alarm signal. It consists of a sensor section that detects longitudinal tears and a converter section that outputs cutting signals. The converter is also equipped with a disconnection alarm output that detects cuts in the sensor or cable, ensuring high safety. 【Features】 ● A highly sensitive cable switch is used in the sensor section. The point that is pressed immediately becomes a contact, allowing for instant detection of abnormalities. ● The conductive part of the touch switch is protected by a safety cover, preventing dust and transported materials from adhering, and it is not affected by ozone, infrared, or other influences. ● The detector can be installed without modifying the conveyor belt itself. It can also be installed on operating conveyor lines. *For more details, please download the catalog or contact us.

Shooting blockage detector "Shoot Switch"

Quickly resolve the confusion in the conveyor line caused by a shoot blockage!

The chute switch is a device designed to issue an alarm signal and emergency stop the belt conveyor when the chute of a belt conveyor or the chute of a tripper is blocked by transported materials. It is mounted on the side wall of the chute and operates by moving a detection plate due to the side pressure from accumulated materials such as ore. The detection plate is installed using dust-proof bearings, allowing it to move smoothly even if dust adheres to it. To prevent issues caused by condensation, a proximity switch type is also available as an option. The detection operating force can be adjusted from 9.8 N to 14.7 N at the tip of the detection plate. Therefore, the chute switch can be used across a wide range of belt conveyor lines, from small powders to bulk materials.

Usage example: Flow detection sensor for monitoring transport on belt conveyors.

Assisting stable operation of the production process! Equipped with enhanced durability detection blades.

We would like to introduce the application examples of the load flow detector 'EFSL-155S' handled by Matsushima Majatech. When there are no items being transported on the conveyor, there may be abnormalities in the upstream processes. Additionally, if the normal transport volume is not flowing, it could significantly impact the downstream processes. This product is suitable for monitoring the status of the conveyor transport line. Its implementation helps ensure stable operations in the production process. 【Example】 ■ Application: Monitoring the transport status of belt conveyors ■ Product introduced: Load flow detector 'EFSL-155S' *For more details, please refer to the PDF materials or feel free to contact us.
