TTU-OPL-010 – MIMS resistive (RTD), with free ends

Description

TTU-OPL-010 – MIMS resistive (RTD), with free ends is used in the temperature range -50 °C to 450 °C.

 

What is MIMS?

MIMS: mineral insulated metal-sheathed; standard: EN 61515. Also often referred to as “MI cable”, mineral insulated cable.

Mineral insulated cable is a type of flexible metal cable used in the manufacture of temperature sensors. It is also known as a mineral insulated metal jacket, or MIMS for short.

The mineral insulated cable is made of a seamless metal tube tightly filled with magnesium oxide (MgO) powder.

The sensor wires run through a metal tube, and a magnesium oxide powder keeps these wires insulated and separated.

 

MIMS or “resistive” sensors are distinguished by their outer diameter:

• exceptional flexibility
• temperature range between -50 °C and 450 °C (we recommend consulting an expert for the most suitable choice)
• excellent resistance to harsh working conditions (almost flame retardant even at high temperatures; oxidation resistant, corrosion resistant, suitable for radioactive areas)
• suitable for temperature cycling (call an expert for advice)
• easy to change (no preheating required)
• flexibility of designs and connection elements
• single, double and triple thermocouple versions
• fast response time
• variety of diameters, most common in single thermocouple: 1.5 mm, 3.0 mm, 4.5 mm, 6.0 mm, 8.0 mm (less common: 0.5 mm, 1.0 mm, 2.0 mm, 4.0 mm, 9.5 mm and others as standard)
• Industry use: all furnaces, kilns, brick kilns, quenching, medical, aeronautics and automotive (CQI directives)
• safety-specific applications: nuclear industry, medical devices, energy installations, oil platforms

 

Due to their flexibility and versatility, MIMS thermocouples are increasingly being used in both industrial and non-industrial environments.

Temperature sensors are often portable measuring equipment, with a miniature connector for plugging into the instrument or connection boards (panels).

They are also used as reference temperature sensors in ON SITE versions.

They are subject to accuracy classes according to SIST EN 60584-1 and colour codes and cables according to SIST EN 60584-3.

 

Features of TTU-OPL-010

• thin versions are particularly suitable for very fast measurements (0.5 mm, 1.0 mm and 1.5 mm)
• Supplied in Class 1 and Class 2 (holding standard Class 1 stock)
• Different types of sensors: K, J, T, N, E
• other thermocouples, but outside the definitions of EN 61515 (S, R, L …)
• different types of sheaths (most common Inconel 600, 1.4541, 1.4571 …)
• low-cost designs

 

Important

in the case of cable extensions, use only the compensating cable,
connectors and electrical terminals
of the same thermocouple! All also available from us as accessories

 

Choice of implementation

Select the desired design using the code list in the Documentation tab, or call us on 02 62 96 720 or write to us on the Enquiry form and let us help you make your choice.

The correct choice of MIMS or resistive thermocouples is very important depending on the application and the conditions of use. Let our experience help you.

We recommend a mounting length of at least ten times (10x) the pipe diameter, shorter lengths have a negative effect on the accuracy of the measurement.

The sensor can also be available in Ex version or in combination with a DIN rail transducer.

 

Benefits of industry versions

For manufacturers, the production of thermocouples from MIMS materials is one of the most demanding. If not manufactured correctly, temperature sensor manufacturers can severely compromise positive features such as insulation resistance, accuracy, longevity and stability. These processes are therefore subject to stricter and tailored guidance. All this is achieved through a precisely managed and controlled manufacturing process, with strict quality control of the materials in and out.

In some places, MIMS thermocouples are also used as consumables – e.g. melting, etc. Metalworking processes (foundries) where they “dissolve” and users do not pay attention to the quality of the incoming thermocouples.

 

Calibration

All temperature sensors can also be ordered
with accredited certificate
or with verification only in the desired range, and all can be ordered custom-made.

 

Custom temperature sensor

All temperature sensors can be made to your specifications and requirements. The most common designs are presented on the website, but in practice, production is mainly made to order.

Call or email us and we will help you determine/choose the most suitable implementation for you based on your process requirements.

Standard delivery time is 3 working days, but other options include
urgent deliveries within 24 hours (emergency).

 

TTU-OPL in EX version

For use in EX rooms/areas we manufacture/supply TTU-OPL
ATEX certified
(Zone 2 with EX transducer, Zone 0 and 1 with additional barrier).

 

How to order a sensor?

From the Inquiry box, please send your requirements, specifying the operating temperature, the desired dimensions and the intended use. Don’t forget your phone number and email address.

We will call you to confirm your offer before implementation.

NO WORries: we won’t do anything without your prior approval.
