Abstract
A modular, intrinsically-safe power module assembly is provided. The assembly includes a rigid conduit adapter configured to mount to a conduit of a field device. A housing, having an interior, is operably coupled to the rigid conduit adapter and is physically supported by the rigid conduit adapter. At least one non-rechargeable battery is disposed within the housing. Intrinsic safety circuitry is coupled to the at least one non-rechargeable battery, and is coupled to a connector that mates with a cooperative connector in the rigid conduit adapter.
Claims15
A wireless field device for use in an industrial process, comprising:
- a field device housing configured to contain a process variable sensor and mount proximate a process installation and including an electronics compartment having a conduit entry formed therein;
- a rigid conduit adapter having a first end configured to mount to the conduit entry of the field device;
- a module housing operably coupled to a second end of the rigid conduit adapter and physically supported by the rigid conduit adapter, the module housing having an interior;
- at least one non-rechargeable battery disposed within the module housing;
- and
- intrinsic safety circuitry coupled to the at least one non-rechargeable battery, the intrinsic safety circuitry being coupled to a connector that mates within the rigid conduit adapter with a cooperative connector disposed in the rigid conduit adapter and thereby power the wireless field device with power from the at least one non-rechargeable battery.
