hotcontrol Thermocouples and RTDs

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.

• 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.
