JOLA- Floating switches For Mines

ALVI Automation in association with ALVI Australia and Jola Germany takes pride to present  the Jola Float Switches in India .

For mounting from the side or from the top.
To ensure a correct switching the cable must be fixed at the required height:
• using a stuffing gland, for example, in the case of mounting from the side or
• using a fixing weight, for example, in the case of mounting from the top.
These units are not suitable for use in turbulent liquids (e.g. in stirrer tanks).
