Cement | flour | bulk material rotary | rotating level switch | sensor | 230VAC | 5A/250V SPDT | high-pressure 1.6MPa | IP65

This model differs from the standard version because it is designed for operation in pressurised process tanks and equipment. The maximum operating pressure is 1.6MPa. This allows the switch to be used in processes where a conventional model intended for normal atmospheric pressure would not be sufficient.

This version is designed for processes where the pressure may reach up to 1.6MPa. The specified limit must not be exceeded. When designing the installation, it is necessary to consider not only the operating pressure of the switch itself, but also the suitability of the process connection, thread, sealing components and the complete mounting assembly for the specific pressure.

The integrated microswitch has an SPDT changeover contact with an electrical rating of up to 5A / 250VAC. The contact can be used to transmit a point-level signal to a PLC, contactor, interposing relay, visual or audible alarm, or other compatible control equipment.

When installing the switch in a pressurised tank, proper mechanical fixing and sealing of the G1" process connection must be ensured. Sealing components, adapters and other installation parts must also be suitable for the operating pressure of the system. The switch pressure rating of 1.6MPa alone does not mean that all additional installation components are automatically suitable for the same pressure.

The high-pressure rotary level switch is intended for processes where the point level of bulk material must be monitored while withstanding process pressures of up to 1.6MPa. It can be used in pressurised process tanks, hoppers, storage equipment and other enclosed systems, provided that the temperature and other process conditions comply with the technical specifications of the product.

• Operating pressure up to 1.6MPa allows the model to be used in pressurised process systems.
• Simple electromechanical operating principle does not require complex continuous level measurement.
• SPDT 5A / 250VAC contact allows the point-level signal to be transmitted directly to a control circuit or interposing relay.
• SUS304 stainless steel paddle is designed for direct contact with bulk material.
• 1 rpm paddle speed is intended for mechanical detection of material presence.
• IP65 protection rating protects the main housing against dust and water jets.
• G1" process connection is intended for fixed installation into a process tank.
• M20x1.5 cable entry is intended for connecting power and signal wiring.
• -20°C to +80°C operating temperature is suitable for various industrial processes.
• 3W power consumption is required to drive the paddle.

• 1.6MPa is the maximum pressure limit: process pressure must not exceed the permitted switch rating.
• Designed for point level rather than continuous level measurement: the switch detects material at a specific point but does not measure the exact filling height.
• Mechanical contact with the material: the paddle must physically contact the monitored bulk material.
• Installation sealing is critical: the G1" connection, adapters and sealing components must be suitable for the actual system pressure.
• Not suitable for liquid level measurement: the operating principle is based on bulk material stopping the rotating paddle.
• Clearance is required for paddle rotation: there must be no tank structures or other obstructions around the paddle.

In a pressurised bulk-material process tank, the rotary paddle switch is installed at the maximum permitted filling level. During operation, the system works under increased pressure but does not exceed 1.6MPa. As long as the material does not reach the paddle, the 230VAC synchronous motor rotates it at approximately 1 rpm. When the tank fills, the bulk material stops the paddle, the internal mechanism switches the SPDT contact, and the signal is transmitted to a controller that can stop material feeding or activate a full-tank alarm.

The main difference is the ability to operate in a pressurised process system. The maximum operating pressure of this model is 1.6MPa.

The maximum operating pressure is 1.6MPa.

Yes, provided that the actual process pressure does not exceed 1.6MPa and that the process connection, adapters, sealing components and complete mounting assembly are suitable for the specific process conditions.

It detects whether bulk material has reached a specific point in the tank. It is a point level switch rather than a continuous level transmitter.

The paddle rotates slowly. When bulk material surrounds it and creates mechanical resistance, rotation stops and the internal mechanism switches the signal contact.

The switch supply voltage is 230VAC.

An SPDT microswitch contact is used, with an electrical rating of up to 5A / 250VAC.

The paddle rotation speed is approximately 1 rpm.

The paddle is made of SUS304 stainless steel.

The operating temperature range of this model is from -20°C to +80°C.

Yes. When installed in the upper part of a tank, the contact signal can be used to stop filling or activate a full-tank alarm.

Yes. When correctly installed in the lower part of a tank, the change in contact state can be used to monitor the minimum material level.

The process connection is G1".

The electrical cable entry is M20x1.5.

The enclosure protection rating is IP65.

The high-pressure rotary level switch must be installed in accordance with the technical requirements applicable to pressurised systems. The maximum operating pressure of the switch is 1.6MPa and this limit must not be exceeded. The G1" process connection, threads, adapters, gaskets and other sealing components must be suitable for the actual operating pressure of the system and the process medium being used. The paddle must be able to rotate freely and must not be continuously exposed to a strong direct flow of material. Electrical 230VAC connection work must be carried out by a qualified specialist with the power supply disconnected before work begins. The 5A / 250VAC SPDT contact rating must not be exceeded. For explosive, aggressive or other special environments, the suitability and certification of the specific model must be additionally verified.
