ET20x Series RTD Probes with Cable 1.21

? For measuring temperatures from -50 to +500 ° C? Pt100, Pt500, Pt1000, PTC1000 or NTC resistance sensors ? Double RTD sensing element option ? Available in 2-wire, 3-wire or 4-wire circuit ? AISI 316 stainless steel protection tube ? PVC, silicone, teflon or fiberglass insulated cable

ET20x series push-in resistance temperature probes are intendedfor measuring temperatures in liquids and gases. Applicationsinclude heating and cooling installations, building and industrialautomations, labs.Depending on the needs of application it is possible to order eitherplatinum RTD sensing element with specific nominal resistanceand accuracy class for temperatures up to +500 °C or common thermistors, protection tubes of various-sizes, connecting cablesfor dry and humid conditions, various fasteners and flexible steelarmour for cable.The standard version includes Pt100 class B sensor withmeasuring range from -50 to +250 °C and 3 meters of 3-wire silicone insulated cable.Sensing element - Pt100, Pt500 or Pt1000 RTD sensor, class B, A, 1/3B or 1/10B according to EN 60751, measurement range -50...+250 °C or -50...+500 °C - PTC1000 thermistor (1000 Ohm @ 25 °C), range -30...+150 °C - NTC10A thermistor (10 kOhm @ 25 °C), range -30...+150 °CProtection tube 1.4404/AISI316L acidproof steel Ø3...15 mm, L30...2000 mm (stock tubes have Ø4 and Ø6 mm and length L = 30/80/130/190/230/290/380/530 mm), PTFE coating option for agressive conditionsConnection cable 2-, 3- or 4-wire circuit, shielded or not; maximum operating temperature (continuous/peak): - silicone insulation 180/230 °C, - teflon insulation 260/310 °C, - fiberglass insulation 480/530 °C standard (IP55) or waterproof (IP68) protection tube to cable transition with strain relief.Accessories - flanges and screw fittings, series EA0xx - threaded compression fittings, series EA1xx - threaded thermowells, series EA2xx - flexible stainless steel armour for cable, series SSAxTo provide 4-20 mA / 0-10 V analogue output or digital RS485Modbus RTU interface, E2060 series industrial transmitters mountable onto wall or DIN-rail are available.
