Thermocouples

A ther­mo­cou­ple con­sists of two wires of dif­fer­ent ma­te­r­i­al, which due to the ther­mo­elec­tric ef­fect gen­er­ate a volt­age from which the tem­per­a­ture can be derived.Depending on the de­sired ap­pli­ca­tion tem­per­a­ture, you can choose dif­fer­ent thermocouples.

The mea­sur­ing point can be man­u­fac­tured po­ten­tial-free as well as po­ten­tial-con­tain­ing. Lim­it de­vi­a­tions can be se­lect­ed ac­cord­ing to class 1 or class 2.

Prop­er­ties and ad­van­tages:
  • Al­so ap­plic­a­ble in high­er tem­per­a­ture ranges, such as. Types B, R and S which are tem­per­a­ture re­sis­tant up to 1600°C
  • Short re­sponse time to tem­per­a­ture changes for fast re­ac­tions of the con­trolled sys­tem, es­pe­cial­ly with po­ten­tial-con­tain­ing mea­sur­ing point
  • Ro­bust to me­chan­i­cal stress and less sen­si­tive than e.g. re­sis­tance ther­mome­ters to shocks and vibrations
  • Very com­mon and well-known sen­sor type
  • Ef­fec­tive­ly priced

RTDs

In many ar­eas of in­dus­try, tem­per­a­ture is mea­sured with re­sis­tance ther­mome­ters. For this pur­pose, an ohmic re­sis­tor is used as the tem­per­a­ture sen­sor. Its re­sis­tance val­ue is tem­per­a­ture-de­pen­dent. Plat­inum has be­come es­tab­lished as the re­sis­tor ma­te­r­i­al. The most com­mon­ly used plat­inum al­loy bears the des­ig­na­tion Pt100, which we man­u­fac­ture in ac­cor­dance with DIN EN 60751.Other types of sen­sors avail­able in­clude. For example:

  • Pt100
  • Pt500
  • Pt1000
  • Ni100
  • Ni120
  • var­i­ous NTC sensors
In or­der to min­i­mize the in­flu­ences of the line re­sis­tances and their tem­per­a­ture-de­pen­dent fluc­tu­a­tions, we man­u­fac­ture not on­ly sen­sors with 2‑wire con­nec­tions but al­so those with con­nec­tions for 3- and 4‑wire cir­cuits. You can se­lect the lim­it de­vi­a­tion ac­cord­ing to class A or class B.

Prop­er­ties and ad­van­tages:
  • high­er mea­sur­ing ac­cu­ra­cy than thermocouples
  • best long-term stability
  • high chem­i­cal re­sis­tance due to platinum

Designs of the temperature sensors

Sen­sors of all de­signs can ba­si­cal­ly be sup­plied as ther­mo­cou­ples and re­sis­tance thermometers.

Min­er­al-in­su­lat­ed ther­mo­cou­ples / sheathed re­sis­tance ther­mome­ters, al­so known as min­er­al-in­su­lat­ed ther­mo­cou­ples / re­sis­tance ther­mome­ters, rep­re­sent a spe­cial de­sign of tem­per­a­ture sen­sors. They con­sist of a flex­i­ble thin-walled sheathed ca­ble, which en­ables a long ser­vice life due to its vi­bra­tion-re­sis­tant con­struc­tion. They dif­fer from oth­er tem­per­a­ture sen­sors by their com­pact de­sign, short re­sponse times to tem­per­a­ture changes and pli­a­bil­i­ty, so that they can al­so be brought to mea­sur­ing points that are dif­fi­cult to access.

The sheath is easy to weld and sol­der due to the ma­te­r­i­al (1.4541 and 2.4816), has the best strength prop­er­ties at high­er tem­per­a­tures and meets the typ­i­cal re­quire­ments in en­vi­ron­ments with gaseous and liq­uid media.

Con­nec­tion plugs and com­pres­sion fit­tings are avail­able in nu­mer­ous variations.

Con­nec­tion types:

  • Open ends
  • Tran­si­tion sleeves
  • LEMO con­nec­tors
  • Com­pen­sa­tion connectors
  • Mi­ni com­pen­sa­tion connectors
  • Nu­mer­ous oth­er con­nec­tion types on request.

Fre­quent applications:

  • Hot run­ner nozzles
  • Fume gas analysis
  • Fur­nace construction/plants
  • Steel works
  • Lab­o­ra­to­ries
  • Test fa­cil­i­ties and test benches

Suit­able for tem­per­a­ture de­tec­tion on in­jec­tion and die cast­ing molds in plas­tic and zinc die cast­ing. An­gle sen­sors are ad­van­ta­geous wher­ev­er no straight ca­ble out­let is pos­si­ble or de­sired, e.g. for rea­sons of space. The an­ti-kink spring of the con­nect­ing ca­ble serves as me­chan­i­cal pro­tec­tion. The fas­ten­ing is car­ried out, for ex­am­ple, with a com­pres­sion fit­ting or a screw-in thread.

Plug-in sen­sors are prefer­ably used for tem­per­a­ture mea­sure­ments in solids, e.g. hot glue ap­pli­ca­tion heads or weld­ing / seal­ing jaws of pack­ag­ing machines.
The tran­si­tion of the ca­ble to the pro­tec­tive tube is strain-re­lieved. The stain­less steel ther­mow­ell pro­tects the mea­sur­ing point against chem­i­cal in­flu­ences and me­chan­i­cal damage.
Fix­ing is by di­rect in­ser­tion in­to the bore­hole or by a flange.

Ther­mo­cou­ples and re­sis­tance ther­mome­ters with bay­o­net lock are prefer­ably used for tem­per­a­ture mea­sure­ments in solids, slid­ing bear­ings and tools, e.g. in the plas­tics in­dus­try dur­ing plas­tic in­jec­tion mold­ing or extrusion.

Due to the spe­cial shape of the mea­sur­ing tip, these tem­per­a­ture probes are suit­able for use in flat and point­ed bores.
The di­men­sion­al­ly sta­ble pres­sure spring made of rust- and acid-re­sis­tant stain­less steel, which al­so as­sumes the bend pro­tec­tion, en­sures a con­stant con­tact pres­sure of the mea­sur­ing tip in the bore­hole. The in­stal­la­tion length can be var­ied by twist­ing the bay­o­net cap.

The di­am­e­ter of the bay­o­net cap is avail­able in sev­er­al dimensions.
Screw-in adapters are avail­able in var­i­ous designs.

Ring ther­mo­cou­ples were de­vel­oped for tem­per­a­ture mea­sure­ment on sur­faces. These are easy to at­tach with a screw and are suit­able for nu­mer­ous ap­pli­ca­tions, e.g. hot run­ner manifolds.

For tem­per­a­ture mea­sure­ment on pipelines and all cylin­dri­cal shapes. At­tach­ment is by weld­ing or sol­der­ing. The an­ti-kink spring of the con­nect­ing ca­ble serves as me­chan­i­cal protection.

Com­mon terms are al­so pipe clamp ther­mome­ters or pipe clamp re­sis­tance ther­mome­ters. They are used for tem­per­a­ture mea­sure­ment on pipelines and cylin­dri­cal bod­ies. Fas­ten­ing is done with the ad­justable clamp­ing band. The an­ti-kink spring of the con­nect­ing ca­ble serves as me­chan­i­cal protection.

For tem­per­a­ture mea­sure­ment on molds, e.g. hot run­ner manifolds.
This sen­sor is par­tic­u­lar­ly space-sav­ing and easy to at­tach to the flange with a screw. The an­ti-kink spring on the con­nect­ing ca­ble serves as me­chan­i­cal protection.
