Selecting the best electrical connection option for a pressure transducer requires some forethought. Given the increase in third-party agency approvals and expanded use of transducers and transmitters in commercial and industrial applications, the available options have grown and made the process more problematic. In simplest terms, understanding where, who, and what types of sensors are being installed are basic steps to selecting the best connection.

Where is it being installed?

Hazardous areas
For explosion-proof environments, a pressure transducer is typically wired into a junction box, and cable is run through conduit according to the electrical code. With certain instruments, the junction box is integral to the transducer, so terminations are made within the housing. The length of the cable can be limited, and electrical terminations coming directly from the transducer are limited to cable options.
