Pt100Pt1000Pt500

- resistance intrinsically safe temperature sensor for hazardous areas - ATEX Exi approval: II 1G Ex ia IIC T4-T1 Ga; II 1D Ex ia IIIC T135°C÷450°C Da - temperature range -40...+550°C - operating temperature of connection heads max. 150°C - stainless steel sheath - threaded process connection - optional: sensor with a replaceable measuring insert - possibility of mounting a 4…20 mA temperature transmitter The resistance thermometer SCR103-Exi consists of an exchangeable measuring insert, outer protective tube (thermowell) with neck, and aluminum connection head. Mounting a temperature transmitter with 4...20 mA output signal is possible. The measuring insert represents the replaceable element of the complete sensor, which reduces the time and costs of maintenance of the measuring apparatus installed in the object. Spring fixation of the measuring insert provides perfect pressure to the bottom of the protecting tube, reduces the time of reaction of temperature changes, and increases the accuracy. It also reduces natural vibration. Thus, mechanical and electrical defects can be avoided. Application areas: - fine chemical industry, - light energy industry, - general industrial services.
