          90.2425 熱表用熱電阻溫度傳感器,PTB認證,帶連接電纜
          90.2425 Heat meter resistance thermometers with connecting cable, PTB approved
          產品特點:
              ■ for temperatures from 0 to 180°C, Type Direct Short (DS), Direct Long (DL), Pocket Long (PL) and Pocket

          Short (PS)
              ■ approved to calibration regulations EO 22 and EN 14 34 as interchangeable
              ■ temperature probes according to AGFW regulation FW 202
              ■ paired and certified in-house
          產品應用:
              Heat meter resistance thermometers Type PS are preferably used for temperature measurement
          in closed pipe systems. Mounting in ball valves avoids drainage of the system for
          installation purposes and replacement after the end of the certification period.
              The versions Type PL and PS are preferably fitted in pockets with close tolerances, which
          have the relevant approval. For correct temperature acquisition, it has to be ensured that
          the external diameter of the temperature probe matches the appropriate and approved internal
          diameter of the pocket.
              The measuring insert is normally fitted with a Pt100 temperature sensor to EN 60 751,
          Class B in 2-wire circuit. Versions with Pt500 or Pt1000 are also approved. 4-wire connections
          can be provided.
              The resistance thermometers can be measured, paired and certified at temperatures between
          20 and 200°C in the in-house Heat Test Laboratory KF2, which has state approval,
          or in the accredited test laboratory.
