Heat Trace and Surface Sensors

Close Heat Trace and Surface Sensors Zoom
  • Accurate Surface Temperature Measurement of Process Pipes, Tanks, Vessels, and Containers
  • Models With and Without Integrated Transmitter within Sensor Tube Body
  • Flat or Curved Heat Transfer Pad for Direct Contact and Quick Response
  • Optional Terminal Heads and Other Termination Configurations

Offered with and without transmitter, the Vulcan Electric Heat Trace and Surface Temperature Sensors are designed to measure the surface temperature of process pipes, tanks, vessels, and containers. These units incorporate sensor contact pads configured for direct contact to the pipe or other surface for optimum heat transfer and quick response. Vulcan Heat Trace sensors are an ideal choice for liquid or gas pipe distribution systems and surface related measurements.

Integrated Temperature Probe and Transmitters (ITPT models) incorporate RTD sensing and employ a patented construction with the transmitter encapsulated inside the body of the sensing tube. The RTD sensor with integral 4 to 20mA transmitter provides superior accuracy, repeatability and response time, all in one compact unit. The ITPT units are fully programmable. They can be factory calibrated to your precise requirements or with the optional ITPT PKIT-2 programming module and PC based software, recalibration can be done in the field within your specific application.

Models without the integrated transmitter in tube construction are offered with either Thermocouple or RTD sensing options and are available with or without terminal heads. These units are also available with an optional transmitter located in the terminal head. Although not as compact as the ITPT construction, these units offer similar robust construction features with higher temperature range capabilities.
