  • Comments

IFM SA4300 is a calorimetric flow sensor with display for liquid and gaseous media in a high quality stainless steel housing.
The extended probe 200 mm is suitable for installation in pipelines with large diameters. Reliable electronic flow sensor for water, oil, glycol, air and other media at temperatures up to +100 degrees (for operation at high temperatures, it is necessary to mount the sensor so that the distance between the pipeline and the body is > 50 mm).

SA4300 has two independent outputs:

  1. The first can be used for an IO-Link interface, or a digital or frequency output signal for flow.
  2. The second is used either as an external input, or to control the flow or temperature of the medium with analog 4-20 mA, frequency or discrete signals.

For ease of setup and visual display of the current state of the flow and the switching point on the body of the SA4300 flow sensor, there is an LED display with red or green symbols. The flow rate sensor is configured using the buttons on the housing or via the IO-Link interface. The top of the housing with display rotates 345 degrees around its axis for optimal visual control.
