OWEN ДТСXX4. Руководство по эксплуатации и техническому обслуживанию — промышленный термометр (EN)

Table 3 – Electrical resistance of the insulation between the circuits of the SE and between the chain of SE and the metal part of the protective armature at a test voltage of 100 V DC ДТСХХ4 Resistance termometer Short guide This manual is intended to familiarize service personnel with the installation and operation of the resistance termometer ОВЕН ДТС with the cable terminal (hereinafter referred as sensor). More detailed information about the sensor is given in the Operation Manual (see the device page on the website: www.owen.ru ).

Table 4 – Minimum immersion depth Scope The sensor is designed for continuous measurement of the temperature of liquid, vapor and gaseous media, bulk materials and solids that are non-corrosive to the material of the sensor body. The sensor can be used in various industries. Versions Explosion protection ДТС-Exi sensors relate to electrical equipment with explosion protection of the “intrinsically safe electrical circuit type, meet the requirements of GOST 30852.0, GOST 30852.10 and are intended for use in hazardous areas in accordance with the established marking of explosion protection. These sensors are marked with 0Ex ia IIC T1 ... T6 Ga X . The “ X ” means:

connecting sensors to external circuits should be made through intrinsically safe barriers with appropriate intrinsically safe parameters that have valid certificates of conformity with the requirements of ТР ТС ТС 012/2011; installation, connection, operation, maintenance and disconnection of sensors should be carried out in accordance with the technical documentation of the manufacturer; temperature class in the marking of the explosion-proof sensors is selected from the maximum ambient temperature and the maximum temperature of the controlled medium in accordance with Table 5 .

Table 5 – Temperature classes in explosion protection marking Specification Table 1 – General specifications The parameters of intrinsically safe electrical circuits for ДТС-Exi are listed in the Table 6 . Table 6 – Intrinsically safe electrical parameters Installation and connection CAUTION Installation, connection and disconnection of the sensor from the line supplying the measured medium must be carried out in the absence of pressure in the line. NOTICE During installation and operation, the sensor must not be subjected to sudden heating or cooling, as well as mechanical shock.

CAUTION Connect the sensor to the measuring device must be made in strict accordance with the wiring diagram, with the monitor supply voltage disconnected. CAUTION Connecting the sensor in an explosion-proof housing should be made through the barrier of intrinsic protection. The parameters of the intrinsically safe circuits must correspond to the values from Table 6 .
