Introduction

principle

LV30 series products are divided into two types: analog output type and switch output type.

Analog output type: The magnetic floating ball continuously triggers the reed switch in the detection rod with the change of the liquid level, so that the total resistance of the sensor changes, and the signal is converted into a standard 4…20mA signal output by the transmitter.

Switch quantity output type: When the liquid level rises or falls, it drives the stainless steel magnetic float to move up and down, and the float triggers the reed switch in the detection rod to send out a signal.

Features

Long life, can be used for limit monitoring or continuous monitoring of liquid level. The switch type can provide multi-ball and multi-point monitoring, and the analog type can be used in conjunction with monitoring instruments to realize upper and lower limit alarms or continuous control.

application

Low price and long life, it can be used for limit monitoring or continuous monitoring of liquid level. The switch type can provide multi-ball and multi-point monitoring, and the analog type can be used in conjunction with monitoring instruments to realize upper and lower limit alarms or continuous control.
