1.3.2 AP302/3 Sensors
These sensors are threaded style suitable for immersion, insertion and flow-through applications.
Mounting thread size:
3
/
4
inch NPT.
The sensor body is chemically resistant PVDF (Kynar).
— AP302 models have no sensor guard (flush) for use with flat glass. This provides a flow-cleaned configuration.
— AP303 models have a notched sensor guard. The guard provides an integral protection for normal bulb-style glasses.
