Ascenta PW618 Pressure Sensor 0-10bar 4-20mA Output - Hirschman Connector, M20x1.5 Port

The PW618 uses a standard two-wire 4-20mA loop-powered configuration. Connect the positive supply voltage (8-30 VDC) to one wire of the Hirschman connector, and the return wire carries the current signal to your PLC analog input or receiver. The sensor modulates the loop current proportionally to the measured pressure.

Yes. The sensor's wetted parts and SUS 304 stainless steel housing provide excellent corrosion resistance against many industrial media. The IP65-rated Hirschman connector protects the electrical connections from dust and water jets, making it suitable for damp or washdown environments common in industrial settings.

Gauge pressure, as measured by the PW618, is the pressure relative to the local atmospheric pressure. It reads zero at ambient conditions. This is distinct from absolute pressure (referenced to a vacuum) or differential pressure (difference between two ports). The PW618 is designed for applications where you need to monitor pressure above atmospheric, such as in tanks, pipes, or hydraulic systems.

Not directly. The 4-20mA output requires a loop power supply of 8-30 VDC and is designed for industrial PLCs with analog current inputs. To interface with a 5V microcontroller like an Arduino, you would need an external 250-ohm precision resistor to convert the 4-20mA signal to a 1-5V voltage, and a separate power supply module to provide the required loop voltage.
