JM300 electrostatic capacitance type substance level switch

Product Overview: The capacitive level switch uses the probe (sensing electrode) and barrel wall (grounding electrode) of the switch as the two electrode plates of the capacitor. When the measured object piles up and comes into contact with the electrode, the capacitance between the electrode and the metal tank wall or grounding electrode increases. When the stacking height of the measured object decreases and no longer comes into contact with the electrode, the capacitance decreases and the contact signal returns to its initial state. The unique analysis and processing unit of the level switch detects the magnitude of this change. When this change reaches the set value of the switch, the switch signal output is converted for control, reflecting the height of the measured medium or material interface. Product features ◆ Long service life without transmission mechanism, suitable for various powders, granules, block like objects or liquids. ◆ There are multiple models suitable for various places and industries, with temperatures ranging from -20 to 200 ℃ and high temperatures of 800 ℃. ◆ It has an action delay function, with an adjustment range of 0-6 seconds. The protection level of the junction box is IP-65. ◆ Multiple sensitivity levels can be freely adjusted, with action delay function and adjustment range of 0-30 seconds; ◆ Multiple power sources can be selected as 110V/220VAC or 24VDC, with two output options: NPN transistor and 5A/250VAC CSPDT relay; The standard connecting mouth is R1, and special specifications can also be customized; ◆ Easy to install, with internal/external light-emitting diodes for easy on-site debugging and observation of material conditions

Detailed introduction

JM300 electrostatic capacitance type substance level switch

Product Overview
The capacitive level switch uses the probe (sensing electrode) and barrel wall (grounding electrode) of the switch as the two electrode plates of the capacitor. When the measured object piles up and comes into contact with the electrode, the capacitance between the electrode and the metal tank wall or grounding electrode increases. When the stacking height of the measured object drops and no longer comes into contact with the electrode, the capacitance decreases and the contact signal returns to its initial state. The unique analysis and processing unit of the level switch detects the magnitude of this change. When this change reaches the set value of the switch, the switch signal output is converted for control use, thereby reflecting the height of the measured medium or material interface.
