Converters STU are intended for converting the signal of the Pt 100/3850 resistance-type temperature sensing elements to a unified signal 0 to 10 V. These converters can be utilised in any control system compatible with 0 to 10 V voltage output. The case is provided by the console for wall-mounting or a bracket for mounting to the DIN rail. Their standard measuring ranges are listed in the specifications table. Their operating temperature range is -30 to 70 °C. These limits must not be exceeded even for a short time. The sensors arre designed to be operated in chemically non-aggressive environment. Two variants exist regarding to the design of the converter case:
STU Pt: the plastic case is made of POLYAMIDE material, and is identical to, for example, the connection head of S 120 sensors. It is provided with a wall bracket or with a clip for attaching to a DIN rail. The terminal board casing meets the IP 65 ingress protection on accordance with EN 60529 standard, as amended.
DECLARATION, CERTIFICATION, CALIBRATION
- Manufacturer provides EU Declaration of Conformity.
- Calibration – The final metrological inspection – comparison with standards or working instruments – is carried out for all the products. Continuity of the standards and working measuring instruments is ensured within the meaning of the Section 5 of Act no.505/1990 on metrology. The manufacturer offers a possibility to supply the sensors calibrated in SENSIT s.r.o.’s laboratory (according to requirements of the EN ISO/IEC 17025 standard, as amended) or in an Accredited laboratory.
