04.03

Sensors are designed for liquid and loose media temperature measurement by immersion (sensor 04.01), and also solid surface temperature measurement by contact method (sensors 04.03 – 04.06).
Cable temperature-sensing elements of the first tolerance class are used in surface temperature sensor modifications 04.01–04.06.
Cable temperature-sensing elements are armoured with steel tubes 4-8 mm diameter.
Sensor pressing to the surface is equal to 5-15 H.

Technical characteristics

sensor tolerance class:  к1 for details see table 5 page 2-9

Individual corrections to temperature values should be obtained together with the secondary unit in compliance with MI 1607-87.
Note: surface temperature sensors can be supplied with HH506RA-type secondary units.  Uncertainty of measurement of these units is equal to ±(0,3+0,05%Т), where Т – measurable temperature value. The unit has two measuring channels. The unit operates on "krona" battery. The unit supports the following thermocouple types: K, J, T, E, R, S, N. The unit allows to store up to 1000 measured values. The unit can be connected to PC. Description see in "Enclosures" section.
