JM300 electrostatic capacitance type substance level switch

Product overview The capacitor level switch uses the probe (induction pole) of the switch and the barrel wall (grounding electrode) as the two polar plates of the capacitor. When the measured object accumulates and contacts the electrode, the capacitance between the electrode and the metal tank wall or grounding electrode increases. When the accumulation height of the measured object decreases and no longer contacts the electrode, the capacitance decreases and the contact signal returns to the initial state, the unique analysis and processing unit of the level switch detects the size of this change. When this change value reaches the set value of the switch, the signal output of the switch is changed over for control, thus reflecting the level of the measured medium or material interface. Product features ◆ longest life without transmission mechanism, all kinds of powder, grain, block objects or liquid can be applied. The most models, suitable for various places and industries to use the temperature -20~200 ℃, the highest 800 ℃. The action delay function, adjust the range of 0~6 seconds. ◆ The protection grade of the junction box is IP-65. ◆ Multi-gear sensitivity can be adjusted freely, action delay function, adjustment range is 0~30 seconds; ◆ Various power supplies can be 110V/220VAC or 24VDC, and NPN transistor and 5A/250VACSPDT relay can be output. ◆ The standard connection mouth is R1, and special specifications can also be customized. ◆ Easy to install, internal/external light emitting diodes, convenient on-site debugging and observation of material conditions

Detailed introduction

JM300 electrostatic capacitance type substance level switch
Product overview
Capacitor level switch is the use of the switch probe (induction pole) and the barrel wall (ground electrode) as the two plates of the capacitor, when the measured accumulation,
When in contact with the electrode, the capacitance between the electrode and the wall of the metal tank or the ground electrode increases, and when the accumulation height of the measured object decreases, it is no longer in contact with the electrode.
When contact, the capacitance decreases, the contact signal returns to the initial state, and the unique analysis and processing unit of the level switch detects the size of this change.
When the chemical value reaches the set value of the switch, the signal output of the switch is changed over for control, thus reflecting the level of the measured medium or material interface.
Product Features
The longest life without transmission mechanism, all kinds of powder, grain, block objects or liquid can be applied.
The most models, suitable for various places and industries to use the temperature -20~200 ℃, the highest 800 ℃.
The action delay function, adjust the range of 0~6 seconds.
◆ The protection grade of the junction box is IP-65.
◆ Multi-gear sensitivity can be adjusted freely, action delay function, adjustment range of 0~30 seconds;
◆ A variety of power supplies can be selected as 110V/220VAC or 24VDC, and the output is NPN transistor and 5A/250VAC SPDT relay;
◆ The standard connection mouth is R1, and special specifications can also be customized;
◆ Easy to install, internal/external light-emitting diodes, convenient on-site debugging and observation of material conditions
