AS 1000 – AquaSensor Series

The AquaSensor AS 1000 is for the online detection of water in oils, particularly as an OEM sensor for condition monitoring (Fluid Condition Monitoring).
It records the percentage of water relative to the saturation concentration and transmits this saturation level as a 4 … 20 mA signal.
At the same time, the AS 1000 measures the temperature of the fluid and transmits this as a 4 … 20 mA signal as well The AS 1000 thus enables a continuous monitoring of hydraulic and lubrication oils; precise, permanent, and online.

Features & Benefits

  • Saturation Level: 0 … 100%
  • Temperature: -25 … 100ºC
  • Reliable due to its compact and robust design
  • Inexpensive sensor, also for series utilization
  • Not necessary to calibrate to different types of oil
  • Pressure-resistant, even with pulsations
  • Wide fluid temperature range
  • Early recognition of water problems, resulting in avoidance of disruptions

Pressure Transmitters

Pressure transmitters are designed with two channels. Each channel consists of one sensor element and one evaluation electronics. Because of this, the pressure transducer generates two separate pressure-proportional output signals which are independent of one another. The main areas of application are in the mobile or industrial area of hydraulics and pneumatics, particularly in applications with constricted cavity and as sensor elements in mobile, safety-oriented systems such as a load torque display or load torque limitation in loading cranes or work platforms. Additional fields of application can be found in processes with changing media, in which residues could lead to mixing or contamination of the media.

The variant with HSI sensor detection was specially developed for use in conjunction with HYDAC measurement devices HMG 500, HMG 510, HMG 3000, and CMU 1000.

4 to 20 mA or 0 to 10V output signals enable connection to all measurement and control devices of HYDAC electronic GmbH and linkage to commercially available evaluation systems (e.g. PLC controls).

  • The variant with the front-flush diaphragm was specially developed for applications in which the media used could lead to a blockage, gumming-up, or freezing of a standard pressure connection
  • The variant for applications with enhanced functional safety was specially developed for use in safety circuits / safety functions in the context of the functional safety of machines and plants up to PL d – Cat 3 (in accordance with ISO 13849).
  • Utilization in an SIL 2 – system (in accordance with EN 61508) is also possible.
