Product Description

Variable area flow meter water rotameter with alam limit switch
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 are able to send relevant signals at max, Mid and Min flow,the switches are mounted on certain selected position of rail and whenever magnetic float reaches or passes the switch level,signals will be sent out for internal contact actuation of either opening or closing.
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
Protection Levels: IP65
Delay (ON & OFF Position): ≤4mm
4. Installation Hints
Keep off form ambient magnetic disturbance during mounting . such as electric motor.
Flow media should be free from ferromagnetic foreign matter
Ensure pipe or tube to be mounted with the flowmeters free from any potential vibration in case switch contact actuates accidentally.
