JUMO 60003232

Thanks to its impact-resistant housing made of high-quality plastic, the mechanical double construction thermostat is very robust and can also be used under harsh conditions. The measuring systems used work on the principle of liquid expansion and can be used up to a maximum permissible sensor temperature on the temperature controller of 135 ° C and on the safety temperature limiter of 149 ° C. The smooth round copper sensors have a diameter of 6 mm. The sensor length of the temperature controller is approx. 87 mm, that of the safety temperature limiter is approx. 66 mm. The long-distance cables are also made of copper and rolled up inside the housing upon delivery. Taking into account a bending radius of 5 mm, the cables can be led out of the housing as required and laid flexibly. The protective sleeve made of brass, nickel-plated, included in the scope of delivery, has a diameter of 8 mm and can be mounted with a G 1/2 thread A according to DIN 3852/2. The maximum permissible ambient temperature on the housing (protection class IP54) is 80 ° C. The housing is attached directly to the lower part of the housing as a wall mount. The desired switch-off temperature of the temperature controller can be easily set on a scale using a setpoint adjuster. The temperature of the safety temperature limiter can be set on a scale using a screwdriver after removing the housing cover. The set temperature is visible at all times through a viewing window in the housing cover. The temperature controller is characterized by a high switching point accuracy of +/- 3% in the upper third of the scale, the safety temperature limiter has a switching point accuracy of + 0 / -5 K in the upper half of the scale. The built-in temperature compensation reduces ambient temperature influences on the switch head to a minimum. A decisive advantage is that no additional auxiliary energy is required for temperature measurement. The electrical connection is made using PushIn © terminals, which significantly reduces installation time compared to conventional screw connections. The maximum permissible switching capacity is AC 230 volts / 16 A. The temperature controller has a switching difference (hysteresis) of approx. 3 K and automatically switches back to its original state by falling below the switch-off temperature. The switching contact of the safety temperature limiter (terminal 2) is opened after the set temperature is reached and the signaling contact (terminal 4) is closed at the same time. The switch contact is locked automatically and can only be unlocked manually after the temperature at the sensor has cooled down by approx. 10 K. When the temperature at the sensor cools below -20 ° C, the circuit between terminal 1 and terminal 2 also opens, but closes again when the temperature rises. If the measuring system is destroyed, the circuit is opened permanently, unlocking is then no longer possible. The switch contact is then in a neutral position. The thermostat can be used very flexibly and is used both in building automation and in heating, air conditioning and ventilation technology. Other areas of application are the plastics industry, apparatus and machine construction, furnace construction and temperature monitoring in laboratory and climatic cabinets. The device is approved according to DIN EN 14597 and PED and has an EAC approval.
