1-4 Model
One of the most widespread design of temperature probes with an industrial head. It applies to measure temperature of liquid, gas-like and air environments. It may go with a hex fitting and a threaded boss in a kit. The 4-20 mA or RS485 transducer (T-bus/ModBus protocol) can be built in the industrial head.
