The Rototherm / Thermocouple range of temperature assemblies has been designed for all industrial applications
and is manufactured in strict accordance with the companies ISO 9001:2000 Quality System.
The range includes probes suitable for direct insertion into processes without protective thermowells and full
assembles complete with screwed or flanged thermowells and connection heads.
Connection Heads
Our comprehensive range of connection heads provides the best environmental
protection for the electrical terminals on terminal blocks or temperature
transmitters fitted to resistance thermometers or thermocouple inserts.
Temperature Transmitters
Temperature transmitters are used to convert the primary sensing signal,
usually a resistance change for RTD sensors or EMF for thermocouples,
into a standard current signal of 4-20mA.
We offer a comprehensive range of temperature transmitters suitable for thermocouples or platinum resistance thermometers (RTD), these transmitters may be either head or rack mounted. Temperature ranges may be factory set or user adjusted. (Programmable, intrinsically safe, Hart®, Profibus® and Foundation Fieldbus® communication versions are available).
Mineral Insulated Thermocouples
A Thermocouple consists of two electrical conductors of dissimilar material connected at one
end (the hot junction), the two free ends are connected to the measuring instrument via a
reference junction (the cold junction). The connection of these two materials provides an
electromotive force (emf).
Mineral Insulated Resistance Thermometers
A Resistance Thermometer is a temperature sensor constructed from resistance wire wound
into an element. It is used to measure temperature by means of a change in the electrical
resistance with a rise or fall in temperature. The most popular wire used in Resistance
Thermometers is platinum, although nickel or copper can also be used.
Lagging Extensions
Lagging extensions are available in a wide range of lengths, sizes and fittings. Materials
include Carbon Steel and Stainless Steel. They allow the connection head to be positioned
away from the heat source, or through insulating lagging. Nipple/Union/Nipple and
Breakaway couplings allow rapid disconnection for testing, and orientation.
Thermowells
Thermowells are used extensively in the power, process, pharmaceutical and petrochemical industries.
They are used to protect temperature indicators and sensors from process media and to enable servicing
or replacement of sensors without the need to shut down plant.
Our thermowells are precision made to the highest standards of finish in our modern well equipped
machine shop and are manufactured to Rototherm,s high quality standards approved to BS EN ISO 9001.
Thermowells are available fabricated from tube or drilled from barstock or forgings, full material
certification, including original mill and suppliers materials certificates can be provided. If required NACE
standard MR-01-75 requirements can be met.
Our custom-design ability puts us ahead of the competition for providing thermowells. As part of an assembly or
as a replacement, we can provide thermowells of any size, material and specification. As part of our solution
we can also offer stress and frequency calculations to ensure you have the correct design for the job.
