Liquid Level Control

 

Level Switches

parker refrigeration Clark Johnson Co

Level Switches are designed for industrial applications and long-term function. Switches operate according to the capacitive principle detecting presence of any kind of conductive or non-conductive liquid.

  Product Overview

     Specification

 Level Switches are designed for industrial applications and long-term function. These compact and cost-effective switch designs provide reliable and accurate detection of fluid levels in equipment such as liquid separators, high and low pressure receivers, economizers, oil coolers, oil pots and compressors.

 

    Switches operate according to the capacitive principle detecting presence of any kind of conductive or non-conductive liquid.

 

    Features:

    - Plug and Play: No calibration required when installed on ammonia systems

    - Service Friendly: Electronic head and sensor tube can be separated without emptying the vessel

    - Unaffected by foam, splashing and coating

    - Resists high pressures and temperatures

    - LED indication when liquid is present
