Designed for safe monitoring of process temperatures in demanding and safety-relevant applications, such as the oil and gas, chemical and energy industries.

This thermometer is suitable for harsh environments, corrosive substances, and high-pressure conditions, using protection tubes and special materials.

An optional head transmitter with common communication protocols enhances measurement accuracy and reliability compared to directly-wired sensors.

The device supports a modular design with standard terminal heads and custom immersion lengths, and is compatible with marine applications.

Features and benefits

  • Types of protection for hazardous locations: Intrinsic safety (Ex i.a.), flameproof (Ex d), non-sparking (Ex nA)

  • High insert compatibility and design as per DIN 43772

  • Extension neck protects the head transmitter from overheating

  • Fast response time with reduced or tapered tip form

  • High flexibility thanks to modular design with standard terminal heads as per DIN EN 50446 and customer-specific immersion lengths

  • Marine approval
