Gettorf – Sensor expert EGE introduces the separate operating and display unit SDD for the versatile SDI 853 type inline flow meters with an impulse output, which enables remote meter reading and programming of switching points. This configuration allows users to fit sensors directly into pipes even in poorly accessible places without compromising on control and functionality. Programmable functions include two switching points, hysteresis, and on/off delay. The amplifier unit can also be used to set the impulse value. All programmed parameters and the current reading can be accessed via a 7-segment display. Additionally, series SDI magnetic sensors can monitor maximum and minimum values via a switching output which can be programmed as NO or NC. It also detects reversal of flow – in that case, the measurements are displayed as negative values. SDI flow meters have a measuring range of 0.2…80 l/min. With a maximum measurement error of 2% they ensure maximum precision for a wide range of liquids. Combined with the amplifier unit, the sensors are a very cost-effective solution. The amplifier unit is connected via a 5-pole M12 plug connector and can be fitted on a DIN rail or a mounting plate.
