EGE Temperature Sensors: EGE’s programmable temperature sensors feature a compact design and two switching outputs or one analog output. The easy-to-read digital display depicts the temperature to an accuracy of one position after the decimal point.
EGE temperature sensors can be installed in standard T-pieces or welded T-pieces. The packing is made with an additional flat seal or with other suitable materials. Please note the temperature and pressure resistance of the seals for increased process conditions. Fixing the sensor in the T-pieces is only allowed on the screw head of the sensor. After the installation, the display can be turned through an angle of 330° for best reading. In applications with temperatures over +80 °C, the sensor should be mounted from the side into the pipe.
The hysteresis function is for controlling a temperature value. A limiting value can be programmed in this mode. As soon as the measured temperature is higher than the programmed limiting value, the output signals are switched as programmed (NC or NO). The hysteresis value is the different temperatures for the switch-on and switch-off signal of the limiting value. An additional time delay for the switching signals can be programmed for each switching point.
In the frame function mode, the switching function is set depending of a programmed temperature range. The temperature range starts with the programmed lower value and ends with the programmed upper frame value.
The time delay for the switching signal can also be used in this switching mode.
The analog output can be used for transmitting the temperature and getting the proportional current. For that, you assign one temperature for the 4 mA first value and one temperature for the 20 mA last value in the programming mode. Between the temperature values, it is permissible to have a minimal difference of 16 °C / 29 °F.
