RTD Sensor Probes and Assemblies

Resistance temperature detectors, resistance thermometers, platinum resistance thermometers, or RTDs are sensors that measure temperature by means of resistance. RTDs are based on the principle that the electrical resistance of metals changes with temperature.

RTD Sensor Probes

RTD Sensor Probes

The RT series RTD sensor probes come in various styles unique to different applications. Each style consists of a RTD element protected by a sheath with a termination option.

Features:

  • Styles are customizable to almost any application.

  • Manufactured from high quality raw materials that meet industry recognized standards.

  • Fast lead time on styles that utilize standard Aircom materials.

Application: RTD sensor probes are used widely across almost any and every commercial and industrial temperature process control application.


RTD Assembly Model RT6

The RT6 RTD assembly is a resistance temperature detector consisting of a RTD sensor probe, tapered thermowell, conduit nipples, union, spring loading terminal block, and connection head.

Features:

  • RTD sensor probe is removable for verification, maintenance and replacement.

  • Simple design that is used and accepted across multiple process industries.

  • Tapered thermowell profile provides a good strength to response time balance.

Application: RTD assemblies are used widely across almost any and every industrial process control environment.


RTD Assembly Model RT7

The RT7 RTD assembly is a resistance temperature detector consisting of a RTD sensor probe, various fitting options, and optional connection head and terminal block.

Features:

  • Simple design that is used and accepted across multiple process industries.

  • Direct mount process temperature transmitter using the TXUN fitting option.

  • RT7 configuration options allow for many different patterns to be configured for almost any temperature measurement application.

Application: RTD assemblies are used widely across almost any and every industrial process control environment

Break To Length Thermocouple and RTD Sensor

 
Break To Length Sensor Probe

The Break To Length thermocouple and RTD sensor is designed to be used inside thermowells. The temperature sensor is manufactured in such a way that the end user can “break” the sensor to the desired length needed to suit the application.
