Atlas Copco 1089057591 is the pressure transducer that reports system pressure to the compressor controller. It is used on Atlas Copco rotary screw air compressors. This aftermarket version has the same mounting and electrical connector as the original, so it plugs in and bolts on where the old one came off.
Sold as one unit. Check the number on your old part, or in the parts manual for your machine, before ordering.

Wrong pressure reading or fault code
A failed transducer shows a pressure that does not match the gauge, reads zero or full scale, or puts a sensor fault on the controller. Check the plug and wiring first.
Compressor loads and unloads at the wrong pressure
The controller loads and unloads from this reading. A sensor that drifts makes the machine cycle at the wrong pressure or trip on high pressure.
Water or oil in the connector
A connector that has taken water corrodes and gives erratic readings. Replace the sensor and keep the new plug sealed.
Fitting tips
Isolate power and vent the line before unscrewing the sensor. Use a new sealing washer or thread sealant suited to the port, tighten on the hex only, and check the reading against a gauge after start up.
