EGE has extended its range of inline flow and temperature controllers, adding sensors for low flow rates. The new SDN 552/5 and SDN 552/6 series detect flow rates between 50 and 2.000 ml/min as well as media temperatures from 0 to +60 °C, ensuring space-saving monitoring at reduced acquisition costs. Users can choose between sensors with two analog outputs (4...20 mA), two switching outputs, or one analog and one switching output for flow and temperature data. Equipped with a three-digit digital display, the sensors are easy to program: the parameters limit value, hysteresis, NO/NC, time on/off delay and average value can be adjusted to the requirements of specific applications. Current readings and stored parameters can be accessed anytime. The programming functions are secured by an access code which can also be programmed. The sensors are based on the thermodynamic principle and have no moving parts which protrude into the medium. They withstand pressures up to 10 bar and feature IP65 protection. The units are fitted into pipes via a pipe coupling or a hose adapter. Installation on a base plate is possible via integrated threaded bushes. Optionally, a metal installation plate is also available.
