Models covered
These sensors feature a nonincendive design, ensuring they do not become ignition sources during normal operation. With their durable, hermetically sealed construction, they provide reliable performance in harsh industrial environments. ATEX Zone 2 approved accelerometers are available in a variety of styles, including standard size top and side exit connector options, as well as 4-20 mA loop power sensors, to accommodate a variety of condition monitoring applications.
CTC also lists these same part numbers as CSA Class I Div 2, Class Ii Div 1, Class Iii Approved Sensors, IECEx Zone 2 Approved Sensors, CSA Class I Div 2, Class Ii Div 1, Class Iii Approved Sensors — one product range, catalogued more than once. The approvals and options are set out in the model table below.
Choosing a part number
This family covers 15 part numbers. They share the specification in the Specs tab and differ in the details set out in the model table — most often the connector, the exit direction and the mounting thread. Tell us the machine and the measurement and we will confirm the part number.
CTC lists AC935 as a best seller in this family.
