Details
The Aquacomputer MPS Pressure Sensor | Delta 1000 is a differential pressure sensor with two M5 ports and a range of 0 - 1000 mbar, corresponding to a water column of approx. 0 - 1000 cm. It works as a fill level sensor for a reservoir or measures the pressure drop across a filter, a water block or a pump, and it reports over USB or the 4-pin aquabus interface. Fittings are not included.

What the mps pressure sensors are used for
Aquacomputer says the pressure sensors of the mps pressure series can be useful in a variety of situations. Foremost among them is the fill level sensor: it suits virtually any type and size of reservoir, and in this configuration the sensor detects the pressure generated by the water column inside the reservoir.
Another field of application is a differential pressure measurement across filter elements. It monitors residues and clogging, and Aquacomputer calls it a much more precise maintenance indicator than optical inspection. Accordingly, residues and clogging in micro structure coolers can be monitored too. Measured between the inlet and outlet of a pump, the differential pressure serves for operation monitoring and can provide valuable information for hardware testers.
Installing it as a fill level sensor
The sensor must be installed at the same height as the bottom inlets of the reservoir or lower. One port of the sensor, the port "high", is connected to one of the bottom inlets of the reservoir; keep that tubing as short as possible for accurate readings. Additionally, either the second port, "low", has to be connected to a top port of the reservoir, or a pressure equalization membrane has to go into a top port. The G1/4 pressure equalization membrane (53138) is one. A hose from the port "low" to the top must stay filled with air, or the readings become erratic and the real fill level may differ a lot from them. For that reason Aquacomputer strongly recommends the membrane. Fittings and membrane are not included in delivery and have to be bought separately.
Installing it as a differential pressure sensor
Connect both sensor ports to the coolant lines directly before and behind the component you want to monitor, for example with suitable T connectors. The port "high" goes where you expect the higher relative pressure: on a filter or a water block that is the inlet port, with "low" on the outlet port. On a pump it is the other way round: "high" to the outlet port and "low" to the inlet port.
Electronics, alarm output and software
All mps pressure sensors feature an integrated microcontroller with a USB and an aquabus interface, a programmable alarm output and an external temperature sensor input. For monitoring and configuration, the aquasuite software can be downloaded free of charge. The settings are stored in the device's own memory, so the software is not required for operation.
The alarm output can be configured as an rpm signal for a fan connector with fault detection (for example motherboard fan headers). It can also be a switched output, for example to connect a LED. Configured as "power switch", it reaches the motherboard's power switch header through the alarm header to power switch cable (53217), which is not included. Both the pressure and the external temperature sensor input can be configured to raise an alarm.
Four pressure ranges
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. Each one is a differential pressure sensor with two ports:
- mps pressure Delta 40 (art. 53133): range 0 - 40 mbar, a water column of approx. 0 - 40 cm
- mps pressure Delta 100 (art. 53134): range 0 - 100 mbar, a water column of approx. 0 - 100 cm
- mps pressure Delta 500 (art. 53135): range 0 - 500 mbar, a water column of approx. 0 - 500 cm
- mps pressure Delta 1000, this sensor: range 0 - 1000 mbar, a water column of approx. 0 - 1000 cm
On ModMyMods the Delta 40 is item no. 71220, the Delta 500 has carried item no. 71218, and this Delta 1000 is item no. 71249.
What you need to connect it
Two M5 fittings, which are NOT included, go into the connection threads; tighten them gently by hand so the threads in the plastic body are not damaged. Two M3 mounting threads, 24 mm apart, hold the sensor in the case. The USB cable goes to an internal USB header of the motherboard; check that the pin alignment matches before you plug it in. In addition to the USB interface, the 4-pin aquabus interface can directly connect the sensor to an aquaero 5 or aquaero 6 controller (not included in delivery) through the 4-pin aquabus cable (53122). After the first setup, USB may then be removed, and the aquaero supplies the power.
Compatibility
Aquacomputer lists these aquaero controllers for the aquabus interface:
- aquaero 6 XT (53146, 53206, 53250, 53251, 53262, 53263)
- aquaero 6 PRO (53145, 53253)
- aquaero 6 LT (53234)
- aquaero 5 XT (53089, 53125, 53249)
- aquaero 5 PRO (53090, 53252)
- aquaero 5 LT (53095)
The external temperature sensor input is compatible with all Aqua Computer temperature sensors, and these are on Aquacomputer's list:
- Temperature sensor inline G1/4 (53066)
- Temperature sensor inner/outer thread G1/4 (53067)
- Temperature sensor G1/4 (53147)
- Temperature sensor plug&cool (53025)
- Temperature sensor 70 cm (53026)
The aquaero has carried the ModMyMods item numbers 70028 (6 XT), 70027 (6 PRO), 70213 (5 XT), 70174 (5 PRO) and 70175 (5 LT). For the temperature sensors the numbers have been 71162 (inline G1/4) and 71160 (inner/outer thread G1/4).
aquasuite software
Activating this sensor gives you the current aquasuite version with an upgrade service for at least six (6) months; the latest version from that period stays usable with no time limit. The update service can be extended or renewed for a fee, and installation and activation need an internet connection.
