ipf electronic has expanded its product line of IO-Link-capable solutions with flow sensors.
The new SL430020 sensors are suitable for all applications in which the speed or presence of air flows or the air temperature need to be determined. To do this, the devices measure the airflow speed and air temperature in an integrated measurement section and thereby calculate from the flow velocity the flow rate and air consumption relative to a normal state. The air consumption is periodically stored in the sensor in a time interval of 15 minutes.
The function of the flow sensors with IO-Link from ipf electronic is based on the calorimetric principle (thermal measurement principle). Here, the heated measurement element of the sensor is immersed in an air flow and cooled by the air mass that passes by. Another, unheated, measurement element records the temperature of the flowing air. The mass flow is determined by the temperature difference of the two described measurement elements and electronically evaluated.
The following measured quantities can be determined with the new functions: flow velocity (Nm/s), flow rate (NI/min, Nm3/h), consumption (NI, Nm3) and temperature (°C). Limit value monitoring can be performed with the two switching outputs as hysteresis or window function. Alternatively, the flow velocity, flow rate and temperature can be output with the analog output (4 to 20mA).
The settings can be performed either directly on the device with the membrane keyboard or with the help of a connected IO-Link master and corresponding software via a PC.
