Catalogue excerpts

Strap-on Temperature Sensor EE441 strap-on sensors are used for temperature measurement on round ducts and pipes. Typical applications are heating systems (warm and cold water pipes) and solar collectors. In addition to active outputs 0-10 V or 4-20 mA various types of sensing elements such as Pt1000, NTC10k or Ni1000 are available for passive temperature measurement. The innovative IP65 housing and the mounting concept allow for fast and easy installation. EE441 Features External mounting holes » Mounting with closed cover Aluminium contact surface » Mounting on plane surfaces » Very good thermal transfer » Protection against construction site pollution » Fast response time Bayonet screws » Open/closed with a ¼ rotation Hose clamp » Installation on pipes Technical Data Active output Operating temperature Sensing element Output Accuracy Supply voltage (Class III) for 0-10 V for 4-20 mA Current demand Electromagnetic compatibility Passive output 15-35 V DC or 24 V AC ±20% 10 V DC + RL x 20 mA < V+ < 35 V DC DC: typ. 5 mA AC: typ. 12 mAeff EN61326-1, EN61326-2-3 industrial environment Operating temperature (contact area) Sensing element types Measurement current T-Sensor connection Electrical connection -40 °C…+110 °C (-40 °F...+230 °F) see ordering guide typ. < 1 mA1) two-wire screw terminal, 2x max. 2.5 mm2 Insulation resistance Response time τ63 Enclosure material Protection class Cable gland Hose clamp material Storage temperature Working and storage humidity range > 100 MΩ at 20 °C (68 °F) < 1 min polycarbonate, UL94-V0 approved, T-range: -40 °C...+110 °C IP65 / NEMA 4 M16x1.5, UL94-V2 stainless steel (corr. 1.4301 / 304) -30 °C…+70 °C (-22 °F...+158 °F) 5 % rh...95 % rh, no condensation 1) according technical data of the specic T-sensors v1.2 / Modification rights reserved
