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 gas 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 measured values, enabling trend management of dust collector performance to be monitored at values close to JIS measurement methods. Furthermore, it has obtained domestic explosion-proof certification, allowing for use in first and second category hazardous locations (zone 1.2). ● Maintenance consists only of regular probe cleaning. ● Achieves performance equivalent to optical types at a low cost. Measurement range can be switched across 9 ranges from 0 to 1000 mg/m³. Detects particle sizes from 0.3 μm. ● No specialized knowledge is required. Installation, range setting, and sensitivity adjustments are easily made with switch changes. For more details, please click on the related links or download the catalog.

Belt Misalignment Detector "Belt Offset Switch"

It is possible to prevent damage to expensive conveyor belts and falling materials, 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 and sends out alarm signals and emergency stop signals. It can be used to prevent damage to the belt edges and to prevent material from falling 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 return until it moves back by 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 a belt conveyor and outputs an alarm signal. It consists of a sensor part that detects longitudinal tears and a converter part that outputs cutting signals. The converter is also equipped with a disconnection alarm output that detects cuts in the sensor or cables, ensuring high safety. 【Features】 ● A highly sensitive cable switch is used in the sensor part. The pressed area immediately becomes a contact point, 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 processing the conveyor belt itself. It can also be installed on operating conveyor lines. *For more details, please download the catalog or contact us.

Shot 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 emit an alarm signal and emergency stop the belt conveyor when the intermediate chute or tripper chute of the belt conveyor is blocked by transported materials. It is installed on the side wall of the chute and operates by moving a detection plate due to the lateral pressure from accumulated ore and other materials. 【Benefits of Introduction】 By detecting chute blockages early, 1. Overflow can be avoided, reducing dust emissions into the surrounding environment. 2. Damage to the conveyor and the risk of fire can be prevented. 3. It can prevent the supply to the next process from being interrupted, avoiding quality deterioration.

Leak and Tear Detector for Bag Filters 'Friction Static Electricity Method Dust Switch'

24-hour filter tear monitoring! Lightweight model at just 0.5 kg.

The dust switch continuously monitors the filter breakage of general-purpose small dust collectors for 24 hours. It quickly detects fine dust during abnormal conditions and alerts for dust leakage. Similar to the dust monitor, it detects the static electricity generated by the friction of dust hitting the detection probe. It is an easy-to-install work environment protection switch that is ideal for detecting filter contamination and breakage, as well as for environmental measures. 【Features】 ● Easy installation on general-purpose small dust collectors ● Capable of monitoring filters ● Lightweight and compact, and can be directly integrated into PLCs *For more details, please download the catalog or contact us.

Slip detector for rotating equipment "Speed Switch"

Motion sensor for detecting shaft speed of mechanical devices. Easy setup with button operation! LED display allows for quick understanding of conveyor status!

● Non-contact type (Proximity switch type) This is a motion sensor that detects the rotational speed of a mechanical shaft without contact, and a relay operates when the speed reaches a set value. It adopts a protective structure of IP67, allowing use in outdoor environments. Button operation allows for easy setting of any speed from 2 to 3600 P/min. ● Contact type (Drive roller type) This sensor can directly read the speed by making contact with a belt conveyor. It adopts a protective structure of IP67, allowing use in outdoor environments. Button operation allows for easy setting of any speed from 2 to 3600 P/min. ● Shaft coupling type This sensor can directly read speeds in the low-speed range of 0.1 to 99.9 rpm from the rotating shaft. It can be used to confirm whether ultra-low-speed shafts, represented by thickners and low-speed stirrers, are rotating normally. *For more details, please contact us through "Inquiries."

Powder, granule, and lump upper limit detector "Tilt Switch"

A robust level switch for detecting the upper level of powdery or granular stored materials.

The tilt switch is a robust level switch that detects the upper level of granular or bulk stored materials and is not affected by adhesion or the electrical properties of the measured substance. The detection unit operates as a tilt detection level switch when it is pushed by the input material and tilted approximately 15 to 25 degrees, causing the built-in detection ball to move and activate the switch. It can be used in many applications, such as upper limit switches for hoppers and silos or detecting blockages in chutes. 【Features】 ● Not affected by electrical properties ● Strong structure against adhesion and friction ● Capable of detecting powdered and granular materials ● Protection structure IP67 Note: The tilt switch itself is DC specification, so if AC specification is required, please use the converter (AMDC-12C). *For more details, please download the catalog or contact us.
