LZM- Series Acrylic Flowmter with Alarm Limit Switch , Panel Mounted Rotameter Water and Gas Available IP65 Class 4-20MA LZM- Series Acrylic Flowmter with Alarm Limit Switch , Panel Mounted Rotameter 1. PrincipleVariable 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 FeaturesBJ01: 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.
