1-43p Model
One of the variety of the 1-43 model with a spring-loaded free hex fitting and an industrial head. Exd or Exia design. It applies to measure temperature of explosive environments. It may be supplied with a thermowell and a threaded boss. The 4-20 mA or 4-20 mA (HART protocol) transducer can be built in the industrial head.
