All BOLA Temperature Probes are sensors based on platinum resistance changes under temperature influence with a deposited table of values.
The thermocouple itself is located at the end of a PTFEGlossaryPTFEPolytetrafluoroethylene -encapsulated stainless steel tube (material code 1.4571).
The stainless steel tube provides certain rigidity, but can be bent to the requested form by hand, so that the probe can be used at the optimum measuring point.
A connection can either be made by using LEMO® couplings or by connecting the strands of the cable directly to your measuring device. The cable is also encapsulated with PTFEGlossaryPTFEPolytetrafluoroethylene /PFAGlossaryPFA Perfluoroalkoxy and connected tightly to the temperature probe.
Reduction of response time
The probes have tapered tips which reduces the response time considerably.
Chemical resistance and no metal
The PTFEGlossaryPTFEPolytetrafluoroethylene encapsulation provides an almost universal chemical resistance. All parts which are exposed to the medium do not contain any metal.
High measuring accuracy
Due to the four-wire system, the influence of output and transfer resistance is almost eliminated (aberration approx. 0.002-0.004 %/Ohm). A comparison is normally not needed. The length of the cable can be quite long.
Safe to handle
Due to a collar ring at its end, the probe cannot fall into the medium.
