level sensor vtn-5 extension cable

[george7523]

I need to extend my level sensor to around 25ft, because ghl's vtn-5 extension cable is only 16feet. Can I use a regular 25 feet ps/2 extension cable in place of ghl's vtn-5 ? If not, do I have to daisy chain two ghl vtn-5 cable ? Is there a maximum length the extension cable can be ?

thanks.
