Product Details

LZS-25 Plastic Variable Water Rotameter with alarm 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 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.
