The body of the Tem­per­a­ture-Range-Probe is a com­po­nent that cor­re­sponds to a boil­er tube – either with an applied pro­tec­tive lay­er or made of pro­tec­tive lay­er mate­r­i­al. It is named after the front part of the probe, which can be adjust­ed to a freely selec­table, con­stant tem­per­a­ture range. This allows us to record the impor­tant para­me­ters simul­ta­ne­ous­ly over a wide tem­per­a­ture range and also to deter­mine crit­i­cal tem­per­a­ture thresholds.

The TRP can be deployed and removed at any time. Depend­ing on the task involved the dura­tion of expo­sure can range from hours to months. In this way, spe­cif­ic or even sev­er­al vari­able oper­at­ing states can be mapped. After appli­ca­tion, we dis­man­tle the probe body in our lab­o­ra­to­ry if nec­es­sary and exam­ine it on a micro ana­lyt­i­cal lev­el to deter­mine the cause, type and inten­si­ty of the cor­ro­sion or func­tion­al impairment.

The probe design of the TRP is suit­able for a num­ber of dif­fer­ent types of exam­i­na­tion. In addi­tion to mate­r­i­al tests, it can also be used to col­lect find­ings on the cause, mech­a­nism and dynam­ics of cor­ro­sion and foul­ing. Appli­ca­tion sce­nar­ios include the inves­ti­ga­tion of del­i­ques­cence cor­ro­sion, high-tem­per­a­ture chlo­rine cor­ro­sion, salt melt cor­ro­sion as well as thick and/or hard fouling.

A com­bi­na­tion of probe car­ri­er and probe head has been devel­oped for apply­ing the Tem­per­a­ture-Range-Probe (TRP) to spe­cial cas­es. For this a mod­u­lar struc­ture is used. One probe car­ri­er can be used for sev­er­al tests and can be equipped with dif­fer­ent probe heads. There­by, the struc­ture of the probe head can be shaped more eas­i­ly and more economically.

This com­bi­na­tion is espe­cial­ly suit­able for sev­er­al sim­i­lar tests. Addi­tion­al­ly, a pro­tec­tive tube can be installed for this com­bi­na­tion as well as for the stan­dard TRP. In this way, fur­ther degrees of free­dom can be var­ied, such as depth of instal­la­tion and positioning.
