RTD probes with terminal head and replaceable insert

Description

ET*2x series screw-in RTD thermometers with terminal head and replaceable measuring insert are preferred for measuring temperatures in liquids and gases under demanding conditions. Applications include heating installations, ovens, furnaces and plant engineering, as well as industrial automation. The protection tube with welded screw fitting functions as an integrated thermowell and the measuring insert can be replaced without interrupting the process. Depending on the needs of application, platinum RTD sensing elements of specific nominal resistance and accuracy class for temperatures up to ***0 °C, protection tubes of different length, various terminal heads and outputs can be supplied. Measuring insert with sensing element - 1.***4/AISI**6L stainless steel, Ø6 mm various sizes according to protection tube, screw-mountable to terminal head, compression springs for better heat contact with the bottom of protection tube - Pt**0, Pt**0 or Pt***0 RTD sensing element, class B, A or 1/3B according to EN ****1, measurement range ********0 °C or ********0 °C Protection tube Thermowell integrated with terminal head - 1.***4/AISI**6L stainless steel Ø*0 mm, ********0 mm (tubes in stock: E = **0 / **0 / **0 / **0 / **0 mm) - extension neck (length H = *******0 mm) for prevention of terminal head overheating . Welded screw fitting - 1.***1/AISI**6 stainless steel - G1/2 welded screw fitting as standard, G1/4, M*0×1, 5 or other threads by order Terminal heads - types: B: standard aluminium DIN ****9 N: spherical aluminium DIN ****9 with hinged cover S: for agressive environment, DIN ****9, stainless steel - protection class IP*5, on request up to IP*7 - allowed temperature without transmitter: ********0 °C, with transmitter *******5 °C Output - in-head transmitter option - E***0 series transmitters mountable into terminal heads (see: sheet 1.*1) — to provide ***0 mA / ***0 V analog output or digital RS**5 Modbus RTU interface.
