IMPORTANT

Ground  loops,  poor  earthing  and  faulty  electrical  installations  are  a  common  cause  of  sensor 

 

damage. If you are experiencing unusual or erratic readings, please refer to our support document on ground 
loops.

Damage to Cables and Connectors

Please note that integral sensor cables, connectors and plugs must NOT be cut, removed or modified in any way.   
Sensors contain sensitive internal electronics and our cables and connectors are designed to protect the integrity 
of these components. Any modification or alteration to cables and connectors can compromise their integrity 
and will void the warranty. Always use factory-approved/manufactured cables and connectors. Additionally, the 
cable contains a unique identifier laminated to the cable end and this must not be removed or it will also void the 
warranty.

disinfected prior to shipment. Goods should carry a certificate to this effect, for the health and safety of our 
employees. Material Safety Datasheets must be included for all components of the process to which the sen-
sor(s) have been exposed.
