Heavy hammer level gaugeIt is a mechanical contact measuring instrument used to monitor the level of powder, particles, and liquids in containers such as hoppers and silos. It measures the height of materials by hanging a heavy hammer and touching the surface of the material. During measurement, the controller sends a signal to drive the motor to rotate forward, and the heavy hammer descends uniformly under the guidance of the steel wire rope or cable. When the heavy hammer touches the surface of the material, the relaxation of the steel wire rope triggers a sensitive lever action, which in turn activates the micro switch. After the signal is transmitted to the controller, the motor reverses and lifts the heavy hammer back to its starting position. The controller calculates the distance from the top of the silo to the surface of the material by processing the counting signals during the descent and return of the heavy hammer, and combines it with the known silo height to obtain the actual material level height, which is directly displayed on the display panel.
Heavy hammer level gaugeMain advantages:
1、 High precision measurement, reliable data
Mechanical contact measurement principle: By directly touching the surface of the material with a heavy hammer, the influence of electromagnetic interference, dielectric constant and other factors on the measurement results is eliminated, and the measurement accuracy can reach ± 1%, meeting the needs of most industrial scenarios.
Specialized optical measurement system: Some models are equipped with optical sensors, combined with intelligent self calibration technology, which can automatically correct errors and ensure long-term measurement stability.
Large range measurement: The measurement distance can reach tens of meters (some products support customized longer ranges), suitable for different sizes of silos, from small containers several meters deep to large storage tanks tens of meters high, which can be covered.
2、 Strong environmental adaptability and stable operation
Resistant to harsh working conditions:
High/Low Temperature: The electronic chamber can withstand low temperatures up to -40 ℃, and some models support measurement in high temperature environments up to 200 ℃.
Explosion proof design: Designed without electrical components, it can be safely used in flammable and explosive environments.
Anti dust/humidity: Adopting a triple dust-proof design (dust-proof brush, air inlet, measurement room isolation) to avoid interference from medium humidity and viscosity on measurement, especially suitable for heavy dust scenarios such as cement and coal powder.
Strong anti-interference ability: not affected by parameters such as dielectric constant, conductivity, and thermal conductivity of the medium, the measurement results are stable and reliable.
3、 Reliable structure and easy maintenance
Mechanical transmission structure:
No complex electrical components: reduce fault points and lower maintenance costs.
Tensile resistant steel cable: Excellent drive motors and heavy-duty steel cables provide strong tensile resistance, ensuring long-term operational stability.
Anti jamming design:
Dual optical sensors: Accurately determine the status of steel cables without the need for mechanical braking devices, avoiding problems such as tangled wires and jumper wires.
Specialized winding device: ensures orderly winding and retraction of steel cables, reducing failure rates.
Maintainability:
Modular design: replaceable wiping blocks and cleaning brushes, regular cleaning of steel cables can keep the equipment running normally.
Low failure rate: Simple structure, reduces downtime, and lowers maintenance costs.
4、 Intelligent control, flexible application
Multi mode operation: supports automatic and manual mode switching to meet different production needs.
Remote monitoring and data transmission:
Connect with PLC and DCS systems through interfaces such as RS485 and 4-20mA to achieve remote data acquisition and monitoring.
Support IoT technology to transmit data to cloud or local management systems, improving management efficiency.
High and low level alarm function: can set upper and lower limit alarms for material level to prevent material overflow or empty warehouse, ensuring production safety.
Self diagnosis system: Some models have fault self diagnosis function, which can handle abnormal situations such as cable breakage and buried hammer, reducing manual intervention.
