1-23p Model
The model is the specialized thermocouple that is designed to measure temperature of gaz and steam inside of gas-turbine and steam-turbine systems in thermal power system facilities. The sensor is made of the 1.2 mm diameter grounded thermocouple wire (if there is a grounded junction). The sheath is made of the heat proof steel Inconel 600. It's recommended to order the 4-20 mA / RS485 transducer (T-bus/ModBus protocol) in the remote Z67 enclosure with a cable gland and connect it by the compensating cable to avoid overheating.
NOTE! 1-23p model is high temperature proof along whole length of the immersion part, but temperature near the industrial head must stay up to 300°С. The industrial head ensures IP54 protection only up to 120°С.
