## Summary description

The FF PZ-829 B is a liquid level control relay designed for monitoring and maintaining conductive liquid levels in tanks or wells. It operates at 230V with a 6A output and features an adjustable sensitivity range of 1-100kOhm. This device is ideal for industrial and domestic automation systems, ensuring reliable pump control or alarm triggering based on fluid presence.

## Long description

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.
