Wiring Diagram
Q1: Can the capacitive level transmitter be used for liquid shortage detection?
A1: Yes, the capacitive level transmitter can be used for liquid shortage detection by monitoring whether liquid reaches the preset sensing point. When the liquid level drops below the detection position, the sensor changes its output signal and sends feedback to connected control systems, such as PLCs or pumps. This makes it suitable for preventing dry running, maintaining liquid supply, and improving automatic level control in pipelines and equipment.
Q2: What causes false detection in this capacitive level transmitter?
A2: False detection in a capacitive level transmitter can be caused by factors such as incorrect installation, unsuitable pipe materials, excessive wall thickness, improper sensitivity adjustment, or strong electrical interference. Changes in the liquid properties or environmental conditions may also affect sensing performance.Â
Q3: Can this capacitive level transmitter be used for pipeline liquid monitoring?
A3: Yes, this capacitive level transmitter is designed for pipeline liquid monitoring and can detect liquid presence in pipes with an outer diameter of 12-26 mm. The non-flush mounting design allows easy installation without direct contact with the liquid.
Tips: What output should I choose for the capacitive level transmitter?
The suitable output depends on the control system and wiring requirements. This capacitive level transmitter supports multiple output options, including PNP NO, PNP NC, NPN NO, and NPN NC, allowing flexible connection with PLCs, controllers, and automation equipment. Choose a PNP output for systems designed with positive switching signals, or an NPN output for systems using negative switching signals. The NO or NC mode can be selected according to whether the control system requires a normally open or normally closed signal.
