Jumo 60003390 Temperature sensor
Its impact-resistant housing made from high quality plastic makes the 1-pole mechanical body thermostat with changeover contact very robust and can also be used under harsh conditions. The measuring system used works according to the principle of liquid expansion and can be used without any problem up to a maximum admissible sensor temperature of 600 °C. The maximum permissible ambient temperature on the housing (protection type IP54) is 80 °C. The case is fixed directly on the lower part of the housing by a plate flange with two screws with hole spacing 65 mm. The desired shutdown temperature can be easily adjusted with the help of a screw driver after removing the cover on a scale. The set switch-off temperature can be viewed at any time via a window in the housing cover. The safety temperature monitor is characterized by a high switching point accuracy of +0/-5 K in the upper half of the scale. The installed temperature compensation reduces ambient temperature influences at the switching head to a minimum. A decisive advantage is that no additional power supply is required for measuring the temperature. The electrical connection is made by push-in© terminals, whereby the installation time is significantly reduced compared to conventional screw connections. The maximum permissible switching power is AC 230 Volt / 16 A. The thermostat has a switching difference (hysteresis) of approx. 35 K and switches back to the original state automatically after this value is fallen below the switch-off temperature. If the temperature at the sensor cools below -20 °C, the circuit opens between terminal 1 and terminal 2, but closes again automatically when the temperature increases. If the measuring system is destroyed, the circuit is opened continuously and the switching contact is in a neutral position. The safety temperature monitor can be used very flexibly and is used both in building automation as well as in heating, air-conditioning and ventilation technology. Other areas of application are the plastics industry, equipment and mechanical engineering as well as furnace construction, and temperature monitoring in laboratories and climate chambers. The device is approved according to DIN EN 14597 and DGRL and has an EAC approval.This text is machine translated.
