Parker JRS Series Level Lead Switch

A level switch is a device used to detect the level of substances such as liquid, chemical solvent, powders, lumps within tanks, silos, and hoppers. In addition, a level switch prevents overfilling of tanks and silos and ensures tanks do not run too low, possibly interrupting production.

Description

Parker JRS Series Level Lead Switch with Detection balls and detection rods are completely enclosed and thus the products are not affected by pressure, vacuum, or gases. The lead switch is enclosed in a glass tube containing insert gas and thus the products operate safely in combustible gases. When the detection ball moves up and down due to buoyancy, the lead switches fixed to the upper/lower limit contact point positions are sensed.

Features

  • Detection balls and detection rods are completely enclosed and thus the products are not affected by pressure, vacuum, or gases
  • The lead switch is enclosed in a glass tube containing inert gas and thus the products operate  safely in combustible gases
  • When the detection ball moves up and down due to buoyancy, the lead switches fixed to the
    upper/lower limit contact point positions are sensed.
  • Can be used for simultaneous control of water supply/ drainage or alarms for water shortage/full
    water by additionally installing electrode type level switches (21F-G)
  • In particular, types with the control unit not built in the products can be used in regions with  the risk of explosion or cases where the location of detection is far away from the location of  control by installing the power supply part and the amplification part separately.
  • Depending on connections, either N.C or N.O can be used or both can be used.

Applications

Since these products operate regardless liquid resistance, these products are optimum for control  the level of liquids such as :

  • Clean water
  • Waste water
  • Saline solution
  • Distilled water
  • Industrial chemical water
  • Cooking oil
  • Soybean oil
  • Heavy oil
  • Petroleum
  • Insulating oil
  • Mineral oil
  • Alcohol
  • Benzene
  • etc.
