Application

Platinum resistance thermometers allow problem-free temperature measurements with a high level of precision and reliability. Platinum is especially suitable for meeting even the highest measuring technology requirements due to its stability and exceptional reproducibility. Various sensor designs allow an optimum adaptation to the measuring point. The lab sensor models 42441, 42442 are suitable for precision measurements in liquids and baths. Model 42943 is perfect for its use as a reference thermometer.
The needle sensor model 42905 and surface sensor model 42930-0 are very small temperature sensors.

Description

Tolerance classes A, AA, B and C have been defined to ensure replaceability of the platinum resistance thermometers. The permissible deviations are specified by the following numerical equations according to DIN EN 60751.

Class	Tolerance (°C)
AA	0.10 + 0.0017 . t
A	0.15 + 0.002 . t
B	0.30 + 0.005 . t
C	0.60 + 0.01 . t

“t” represents the temperature here. Increased customer requirements have resulted in limited tolerance classes. The tolerance 1/10 DIN is a tolerance limited by 10 times with reference to the tolerance of class B and also only applies to a limited temperature range.
Our Pt100 sensors have the tolerance classes B, A and better.
With the exception of the laboratory sensors, all Pt 100 resistance thermometers in the 42000 series are equipped with 2 m connection cables including plugs. The laboratory sensors are equipped with 6-pin LEMO connectors. Connection cables are required for connection to various devices. (see lower part of the back).
