FF PZ-829 B Liquid Level Control Relay 6A 230V 1-100kOhm

The FF PZ-829 B is a professional liquid level control relay engineered to monitor and regulate the presence of conductive liquids in tanks, wells, or reservoirs. Operating on a 230V power supply with a 6A output capacity, this device provides a reliable solution for automating fluid management systems. It features an adjustable sensitivity range from 1 to 100 kOhm, allowing for precise calibration based on the specific conductivity of the liquid being monitored.

Advantages

This liquid level control relay offers high operational reliability for automated systems, ensuring that pumps or alarm devices are triggered exactly when needed. The adjustable sensitivity range provides significant flexibility, enabling the device to function effectively with various types of conductive fluids. Its robust design is built for consistent performance in both industrial environments and domestic water management setups, minimizing the need for manual intervention in fluid level maintenance.

Suitable for

• Automated filling or emptying of water tanks
• Monitoring liquid levels in wells and boreholes
• Industrial process control for conductive fluids
• Domestic pump automation systems
• Triggering alarms for overflow or dry-run protection

When it may not be suitable

This device is designed exclusively for conductive liquids and will not function with non-conductive substances such as oils, fuels, or distilled water. It is not intended for use in environments where the liquid conductivity falls outside the specified 1-100 kOhm range.

Key specifications

• Supply voltage: 230V AC
• Output contact rating: 6A
• Sensitivity adjustment range: 1-100 kOhm
• Function: Liquid level monitoring and control
• Application: Conductive liquids

How to use

The relay is installed by connecting the power supply and the output device, such as a pump or solenoid valve, to the designated terminals. Probes are placed at the required levels within the tank or well and connected to the relay inputs. Once powered, the device monitors the electrical resistance between the probes. When the liquid level reaches the probes, the internal relay switches the output contact according to the configured logic, either starting or stopping the connected equipment.

What to consider before purchase

• Verify that the liquid being monitored is conductive
• Ensure the pump or alarm load does not exceed the 6A output capacity
• Check that the tank environment is compatible with the probe installation
• Confirm the sensitivity range matches the conductivity of your specific fluid

Usage recommendations

Regularly inspect the probes for mineral buildup or oxidation, as these can affect conductivity readings and lead to inaccurate relay operation. Ensure all electrical connections are secure and protected from moisture to maintain long-term reliability.
