Description

Application

The T53 Explosion-Proof TC Thermometer is engineered for demanding and safety-critical environments, including the chemical, oil & gas, and energy industries. It is built to endure harsh conditions, withstand corrosive materials, and operate under extreme pressures by utilizing durable thermowells and specialized materials. With the option of an integrated head transmitter supporting common communication protocols, the thermometer offers enhanced accuracy and reliability compared to directly wired sensors, along with flexible configuration options.

This sensor assembly is ideal for use in various process industries, such as:

  • Chemical Processing
  • Petrochemical Operations
  • Refineries
  • Offshore Platforms

 


Benefits

  • FM/CSA XP Class I, Div. 1 certified for maximum safety in hazardous environments.
  • Comprehensive temperature measurement solutions from a single provider, featuring world-class transmitters with integrated sensors, designed for heavy-duty process industries.
  • Ready to install and operate right out of the box.
  • Improved galvanic isolation (up to 2 kV) for enhanced safety and performance.
  • Streamlined model structure offers competitive pricing and convenience—one model number covers the sensor, thermowell, and transmitter for a complete solution.
  • iTEMP transmitters ensure long-term stability with accuracy drift of ≤0.05% per year.
