Thermocouple/RTD Large diameter protective tube type for flue and air duct

WR/WZ series ordinary type, flameproof armored thermal resistance/thermocouple has the advantages of slenderness, easy bending, rapid thermal response, vibration resistance, temperature resistance, compression resistance and durability. It can be used for direct measurement, and can also be used as the inner core element of assembled thermal resistance and thermocouple to replace the traditional assembled type. It is especially suitable for installation in special temperature measurement occasions where the pipeline is narrow, curved, and requires fast response. The armored platinum thermal resistance can be used to measure the temperature in the range of -200℃~+500℃, and the product is suitable for use in places with explosive gas in Zone II. Comply with IEC60079 standard, GB3836 standard.

Features
1. The product has small dimensions and good long-term stability
2. Pressure spring type temperature sensing element, good anti-vibration performance
3. High measurement accuracy, flexible installation and use
4. The intelligent type has remote HART configuration and on-site key operation
5. High mechanical strength and good pressure resistance
6. Imported thin film resistor elements, reliable and stable performance
7. Less thermal response time, reducing dynamic error
