The converters of the type STU and STUD are intended for converting the signal of the Ni 1000/6180, Pt 100/3850 or Pt 1000/3850 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 could be provided with the bracket for mounting to the DIN slat. 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 are designed to be operated in a chemically non-aggressive environment.
Two variants exist regarding to the design of the converter case:
1. STU Pt and STU Ni: the plastic case is made of POLYAMIDE material, and is identical to, for wxample, the connection head of S 120 sensors. It is provided with a wll bracket or with a clip for attaching to a DIN rail. The terminal board casing meets the IP 65 ingress protection in accordance with EN 60 529 standard.
2. STUD Pt and STUD Ni: the plastic box is made of TARFLON - IRY 2200, which meets requirements of UL 94 V-O standard. It is intended for installation to a switch board on a DIN rail
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) or in an Accredited laboratory.
