Resistance Temperature Devices

RESISTANCE TEMPERATURE DEVICES (RTD’s) RTD Assemblies can be supplied with or without a transmitter. Transmitters convert the resistance signal from the RTD to a linear analogue or digital output (commonly 4-20 mA). This signal reduces potential inaccuracies by negating the need for compensating output lead wires.

RTD’s

Applications:

RTD assemblies are suitable for most industrial and commercial applications including:

• Air-conditioning and refrigeration systems
• Chemical and petrochemical industries
• Electronics and semiconductor industries
• Energy and power plant technology
• Machinery, plant and tank measurement
• Oil and gas industries
• Offshore exploration and drilling
• Pipeline control and custody transfer
• Power and utilities
• Pulp and paper
• Water and wastewater treatment

Features:

Sensors can be mounted into a thermowell or directly into a process with the use of a fixed, spring loaded or compression process fitting.

RTD Assemblies can be supplied with or without a transmitter. Transmitters convert the resistance signal from the RTD to a linear analogue or digital output (commonly 4-20 mA). This signal reduces potential inaccuracies by negating the need for compensating output lead wires.

The assembly has electrical approvals for explosion proof hazardous locations, intrinsic safety, ingress protection and general purpose areas.

Approvals include CSA, FM, ATEX/IEC and NAMUR. The approvals can be with or without an attached thermowell.

RTD diameters range from 0.125 inch to 0.250 inch and 2 mm to 8 mm. Standard diameters are 0.125 inch & 0.250 inch and 3 mm & 6 mm.

The RTD sensor can be spring-loaded ensuring a positive contact to the base of a thermowell bore.
