Carlo Gavazzi CLD4MA2D115 Conductive Level Sensor

The CLD4MA2D115 conductive level sensor from Carlo Gavazzi is a device designed to monitor the level of liquids in tanks and reservoirs. It uses low-voltage AC electrodes to detect the presence or absence of liquid, activating a relay output that can be used to control alarms, pumps, or other functions.

Technical Features

• Model: CLD4MA2D115
• Type: Conductive level controller in 2 to 4 points with potentiometer
• Sensitivity Range: Adjustable via potentiometer in 3 ranges
• Power Supply: 115 VAC
• Relay Output: 8A/250 VAC, SPDT/SPST (Normally Open/Normally Closed)
• LED Indication: For power connected and output active
• Electrodes: Low-voltage AC
• Installation: 17.5 mm DIN rail
• Connection Cable: PVC of 2, 3, 4 or 5 conductors, normally shielded. Maximum length: 100 m.
• Resistance between conductor and ground: Minimum 500KΩ

Applications

The CLD4MA2D115 sensor is suitable for a wide variety of applications, including:

• Level control in tanks and liquid reservoirs.
• Overflow detection and dry running operation.
• Low level alarm.
• Control of pumps and valves.

Considerations

- The resistance between the conductor wire and ground must be at least 500KΩ.

- It is recommended to use a shielded cable between the probe and the relay, especially if the cable is placed parallel to the power cables.
