WELL | Flowmeter | PRZ-SW Series

Application

Switch on/off is actually magnetic float contact open/close after magnetron bistable exciting. Alarm sound and light are based on the switch position of on/off linked to relays among other partss and elements.

Functions and Applications

BJ01 : High Alarm Limit Switch (HA), BJ02 : Low Alarm Limit Switch (LA). Both the swiches of BJ01 and BJ02 are able to send relevant signal at maximum, middle and minimum 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.

Technical Parameter

• Rated Voltage : max DC24/AC24
• Rated Amperage : max 0.3A
• Steady Current at Switches Opening or Closing : max DC0.1A
• Interruption Capacity: ̃ 10W
• Insulation Impedance : >109 °
• Working Temperature : 0 °C ~ +55 °C
• Protection Grading : IP65
• Displacement (position on or off) : ̃ 4 mm.

Precautions

• Keep off from ambient magnetic disturbance during mounting e.g. large motors etc. • Flow media should be free from ferromagnetic foreign matters • Ensure pipes or tubes to be mounted with the flowmeters free from any potential vibration in case switch contact actuates accidentally.
