The Atlas Copco 1089952502 is a differential pressure sensor for rotary screw air compressors . Its nameplate shows a measurement span of 0.00 to 5.00 bar and a process-connection torque of 5 Nm maximum. That combination points to a device that watches the pressure drop across a filter or separator element and reports it to the controller. This article explains what the part does, where it fits, and which details to confirm with your dealer before you order.
What This Sensor Does
A differential pressure sensor measures the gap between two pressure points rather than a single absolute pressure. In a compressor lubrication or separation circuit, one side of the sensor sees the upstream pressure and the other side sees the downstream pressure. The element inside responds to the difference. A clean filter passes oil with little resistance, so the difference stays small. As the element loads with contaminant, resistance grows and the difference climbs.
The sensor turns that mechanical difference into an electrical signal. A thin diaphragm or a silicon sensing chip flexes with the pressure, and the sensor outputs the change as a proportional voltage or current. The compressor controller watches the signal and raises a service alarm when the reading reaches the threshold. That is how the machine knows a filter is due for change without anyone opening the panel.

1089952502 Pressure Range and Process Connection
The 0.00 to 5.00 bar span is the headline figure on the nameplate. A bar is roughly 14.5 psi, so the full scale reaches about 72.5 psi. Most clean filter elements sit at a fraction of a bar of drop, which leaves the upper span as headroom for a heavily loaded element. A wider span such as 5 bar also tolerates installation variation and brief pressure spikes without slamming the sensor to its limit.
The process-connection torque of 5 Nm maximum is a mechanical installation limit, not an electrical one. This sensor screws into a threaded port on the filter manifold. Tightening past 5 Nm risks cracking the body or stripping the thread; leaving it loose risks a slow leak that the controller reads as a false pressure reading. Use a calibrated torque wrench and stop at the spec.

Where 1089952502 Fits
Sensors of this family sit in the oil circuit of oil-injected rotary screw compressors. They commonly monitor the pressure drop across the oil filter and across the oil separator, two elements that clog on a predictable schedule. When the measured difference crosses the alarm point, the controller flags maintenance. The 0–5 bar span suits these duties because both elements can show a meaningful rise in drop near the end of their service life.
The exact mounting point for 1089952502 depends on the compressor model and build. Atlas Copco fits differential-pressure sensors at different taps across its GA and related oil-injected ranges. Confirm the location on your unit with the serial number before assuming it replaces a sensor at a specific port.
