LZS Wastewater Flowmeter, Rotameter , Variable Area flowmeter with alarm limit switch

LZS-Rotameter with alarm limit switch Available on Water Accuracy:4% F.S Max Temp:60 connection:Pin-board pipe or Thread

LZS-Technical Parameters of LZS Series

1. Principle

Variable Area Flowmeter Alarm Limit Switch has been designed for use in level alarm applications. Include magnetron and dry reed. It consists of a pair of contacts on ferrous metal reeds in a hermetically sealed glass envelope. The contacts may be normally open, closing when a magnetic field is present, or normally closed and opening when a magnetic field is applied.

2. Application and Features

BJ01: High Alarm Limit (HA)

BJ02: Low Alarm Limit (LA)

Both BJ01 and BJ02 available on Max, Mid and Min scales. Limit switch are mounted on a slide track line. When magnet floats approach to the alarm unit, it will sent signal to on and off the contract.

3. Technical Data

Operating Voltage: ≤DC24V or AC24V

Operating Current: ≤0.3A

Constant Current (ON & OFF): ≤0.1A

Rupturing Capacity: ≤1A

Insulation Resistance: >109Ω

Operating Temp: 0°c to +55°c

4. Installation Hints

Keep away from equipment with magnet, such as electric motor.

Can not use in liquid containing magnetic metal impurity.

Pipe Vibration is forbidden.
