TR-200, UHL4, 1488

The temperature regulator of TR - 200, UHL4, 1488, is intended for application in control units of temperature of the nonaggressive liquid or gas environment, switching of chains of direct and alternating current of frequency of 50 and 60 Hz with a rated voltage up to 220B.
TR - 200 temperature relay. The maximum temperature – 200 degrees. Temperature of operation is regulated (adapts the adjusting screw under a protective cover), has 2 normal closed contact. Total length is 155 mm, diameter of a submersible tube of the sensor of 18 mm, M22x1,5 carving, diameter of a cover is 44 mm.
Dilatometric TP - 200 relay. The temperature TR - 200 relay is intended for control, the alarm system and automatic control of temperature of nonaggressive liquids and gases. It is applied in furnaces, washing machines, refrigeration units.
The price is 60 hryvnias (till 17.09.2016)
4000 pieces are available.
Sensitive element of the relay is the dilatometric device consisting of a brass sleeve 1 and springs 2. The TR - 200 relay is installed so that the brass sleeve was, in the environment which temperature, it is necessary to measure. The figured core 3 is fixed in an end face of a brass sleeve. On springs normally closed electric contacts isolated from them are fixed. As the coefficient of expansion of brass is much more, than an invar (the coefficient of expansion of an invar within temperatures from — 50 to + 100 °C is close to zero), at - heating of a brass sleeve 1 it is extended and for a core 6 stretches springs 2. At the same time electric contacts 4 are disconnected. At reduction of temperature the brass sleeve is shortened - and thanks to elastic properties of a spring the 2nd electric contacts become isolated again. Temperature three which are disconnected kongakta, is defined by the size of a gap 9. The preset value of temperature at which contacts of the relay are disconnected is adjusted by rotation of the screw 5. At rotation the screw 5 together with the contact device moves along a motionless nut 6, changing gap size. The relay has limits of control of a preset value of temperature ranging from 25 to 200 °C. An error of operation of contacts of ±5 °C at a speed of change of temperature no more than 0,5 hail. With in a minute. The greatest difference of temperature of short circuit and disconnection of contacts of 5 °C. The most permissible load on contacts of 30 W at a voltage of 220 V of alternating current and no more than 5 W at a voltage of 220 V of a direct current.
