Temperature sensors for particularly rough environments

Optimize plant efficiency and increase measurement reliability

Ex-certified, including Ex-d according to ATEX

  • Industry-leading calibration capabilities allow for Callendar-van Dusen values to give increased accuracy when paired with PTT74 transmitters.
  • Full penetration weld standard on thermowells increases thermowell strength.
  • Tapered tips on thermowells allow for a faster time response

Specifications

Material selection

It is the purchaser’s sole responsibility to make a careful analysis of all process parameters (such as all chemical components, temperature, pressure, flow rate, abrasives, contaminants, etc.), when specifying product, materials, options and components for the particular application. Process Management is not in a position to evaluate or guarantee the compatibility of the process fluid or other process parameters with the product, options, configuration or materials of construction selected.

 Thermocouple

Temperature range

See Table 3 Characteristics of TW74 ThermocouplesZ

Insulation resistance

1,000 MΩ minimum insulation resistance when measured at 500 Vdc and at room temperature.

 Sheath material

FAHM thermocouples are made of a mineral insulated cable design with a variety of sheath materials available to suit both the temperature and the environment. For temperature up to 800 °C (1472 °F) in air, the sheath is made from 321 SST. For temperatures above 800 °C (1472 °F) in air, the sheath is made from Alloy 600.

 Lead wires

Thermocouple, internal – 19 AWG solid wire (max) and 21 AWG solid wire (min.). External extension leads, Type E, J, K, N, R, S, and T. PTFE insulated. 20 AWG (max.) and 24 AWG (min.) Color coded per IEC or ISA standards. Wiring Diagram shows the wire configuration.

 

Thermowell

 Functions

  • Thermowells in large variety protects against mechanical and chemical load
  • The exchangeable inset generates the measuring signal
  • Full penetration weld standard on TW74 thermowells increases thermowell strength.
  • Tapered tips on TW74 thermowells allow for a faster time response.   

Build from mineral insulated cable (MIC)

  • For high vibration, temperature-change resistance pliability and electrical insulation of the probe

 ATEX conformal executions for explosion protection

  • Intrinsically safe for explosion proof assemblies
