Details
The Aquacomputer MPS Pressure Sensor | Delta 40 is a differential pressure sensor with two M5 ports and a range of 0 - 40 mbar, corresponding to a water column of approx. 0 - 40 cm. It reports over USB and, in addition, over aquabus. Please note that fittings are NOT included: the M5 fittings and, for fill level use, the membrane have to be bought separately.

Fill level sensor for a reservoir
Aquacomputer says the sensors of its mps pressure series can be useful in a variety of situations. Foremost among them is fill level monitoring, and that works for virtually any type and size of reservoir. Set up this way, the sensor detects the pressure generated by the water column inside the reservoir.
The sensor must sit at the same height as the bottom of the reservoir, or lower. One port of the sensor, the port "high", is connected to one of the bottom inlets of the reservoir, and the tubing between them is kept as short as possible for accurate readings. Additionally, the second port ("low") either runs to a top port of the reservoir, or a pressure equalization membrane is installed in a top port. A hose on the port "low" has to be filled with air, otherwise the readings become erratic. For that reason Aqua Computer strongly recommends the membrane.
Differential pressure across a filter, cooler or pump
Another field of application is differential pressure measurement across filter elements, to monitor residues and clogging, and Aquacomputer calls this a much more precise maintenance indicator than optical inspection. Residues and clogging in micro structure coolers can be monitored accordingly. Measured between inlet and outlet of a pump, the differential pressure serves operation monitoring and can provide valuable information for hardware testers.
Both sensor ports are connected to the coolant lines directly before and behind the component, for example with suitable T connectors. The port "high" goes where the higher relative pressure is expected: the inlet port of a filter or a water block, and the outlet port of a pump.
Electronics, alarm output and software
All mps pressure sensors feature an integrated microcontroller with a USB and aquabus interface, a programmable alarm output and an input for an external temperature sensor. Pressure and the external temperature reading can each be configured to raise an alarm.
The alarm output can be configured as an rpm signal for a fan connector with fault detection, for example the motherboard fan headers. As an alternative it works as a switched output, for example to connect a LED. Configured as a power switch output, it connects to the motherboard's power switch header through the alarm header cable (53217), which is not included.
The aquasuite software for monitoring and configuration can be downloaded free of charge. When you activate the sensor you receive the current aquasuite version with an upgrade service for at least six (6) months. After it expires, the latest version from that period stays usable without a time limit; the service can be extended or renewed for a fee. Installation and activation need an internet connection.
Pick the right pressure range
At the moment, four versions of the mps pressure sensor are available, and they differ in pressure range. Please select the sensor best fitting your requirements:
- mps pressure Delta 40 (art. 53133): differential pressure sensor with two ports, range 0 - 40 mbar (water column approx. 0 - 40 cm)
- mps pressure Delta 100 (art. 53134): differential pressure sensor with two ports, range 0 - 100 mbar (water column approx. 0 - 100 cm)
- mps pressure Delta 500 (art. 53135): differential pressure sensor with two ports, range 0 - 500 mbar (water column approx. 0 - 500 cm)
- mps pressure Delta 1000: differential pressure sensor with two ports, range 0 - 1000 mbar (water column approx. 0 - 1000 cm)
This Delta 40 is ModMyMods item 71220. The Delta 500 has carried item number 71218 and the Delta 1000 carries 71249.
What a run needs
Each M5 port takes one fitting, tightened gently by hand so the threads in the plastic body are not damaged. For fill level use, a G1/4 pressure equalization membrane (53138) goes into a top port of the reservoir. The internal USB cable goes to a USB header of your motherboard. To connect the sensor directly to an aquaero 5 or 6 controller (not included in delivery), use a 4-pin aquabus cable (53122). Once it is configured on the aquaero, the USB link may be unplugged, and the aquaero then supplies power over aquabus.
Compatibility
Aquacomputer lists these controllers for the aquabus interface:
- aquaero 6 XT / PRO / LT
