HazLoc qualified transducers type 7ME39501xxxx and 7ME39502xxxx are installed in the
enclosures and prewired to the Junction Box. All connections to the transmitter are made in
the Junction Box, which also houses the Resistive Temperature Device (RTD).
Note
2
See table below for the appropriate drawing defining the circuit connection restrictions
dependent on transmitter type and hazardous area ratings.
Note
3
The spool meter body has two line taps for end user temperature, pressure and other
sensors. Ensure that any devices used are appropriate for the area rating.
Note
4
Sensor Model numbers 7ME362... and 7ME363... can be used with any of the transmitter
types indicated in the Hazardous Area Ratings table below. The area ratings shown define
the permitted locations for sensor installation. Refer to the specific drawings for additional
restrictions of the transmitter location area rating.
