An explosion proof electrical feedthrough assembly is provided in a process variable transmitter (10) which has a sensor (32) sensing a process variable and providing a sensor output signal indicative of the process variable. The transmitter (10) also includes a processing circuit (18) coupled to the sensor (32) to receive the sensor output signal and provide a transmitter output signal based on the sensor output signal. The feedthrough assembly includes a terminal block (20) which is coupled to the processing circuit (18) and includes power supply terminal connectors (54, 56) and communication signal connectors (40, 42). The communication signal connectors (40, 42) are arranged generally radially about the power supply terminal connectors (54, 56).
Ensemble traversée de connexion électrique, de type antidéflagrant, dans un émetteur (10) réagissant aux variables de processus, équipé à cet effet d'un capteur (32) qui détecte les variables de processus et fournit un signal de sortie correspondant auxdites variables. L'émetteur (10) comprend aussi un circuit de traitement (18) couplé au capteur (32), pour recevoir le signal de sortie de celui-ci et fournir lui-même un signal de sortie d'après le signal de sortie du capteur. L'ensemble proprement dit a un bornier (20) couplé au circuit de traitement (18), des bornes d'alimentation (54, 56) et, enfin, des bornes pour signaux de communication (40, 42), lesquelles sont généralement disposées en configuration radiale par rapport aux bornes d'allimentation (54, 56).
