  • The display can be rotated and thus guarantees optimum operation in any mounting position

Application description:
  • The completely fully electronic contact pressure device Precont MAC combines the advantages of a mechanical pressure gauge with the accuracy and longevity of a fully electronic pressure sensor. Therefore, on the large color TFT display of the Precont MAC a pressure gauge in the classical form is modeled to provide a quick and easy reading of the pressure.
  • The measuring element itself consists of a high-purity ceramic capacitive cell, which guarantees the highest accuracy , robustness and long-term stability.
  • The device has a switching output, in which both the switch and the reset point, and NC or NO contact function can be set. The set switching thresholds also appears in the display. The 4 -20mA analog output can be configured freely at zero and end points and provides the possibility to pass the measured value eg as with classical pressure sensors to the control.
  • The Operation is simple using visual keys that work safely even at pollution of the control surface.
  • The great advantage of Precont MAC is that in this contact manometer mechanical moving parts such as bourdon tubes or stepper motors has been omitted. Because of that the system is much more durable and less susceptible to vibration and temperature fluctuations.

Weight0.38 kg

In agricultural and forestry enterprises of all company sizes of, but also in municipal and horticultural facilities, more and more goods and products are loaded and transshipped, which are moved with front loader tractors and forklifts. The interest is growing for already seeing how much weight is currently in the bucket or on the pallet fork when lifting the goods.

Fields of activity:

  • Simple amount detection when handling of goods 
  • No overloading of vehicles 
  • Exact dosage e.g in feed mixtures
  • Amount detection e.g. at substrate introduction in biogas plants 
  • Weight detection e.g. for firewood for moisture determination

Usage:
  • With Precont TN ACS-CONTROL-SYSTEM offers a digital pressure gauge, which is predestined for just such applications. The installation is very simple and can be performed by the user themselves at all front loaders and forklifts. The pressure gauge is built in to the pressure line to the lift cylinder. Via the pending hydraulic pressure, the weight of the load is measured. For the calibration of the system, only the attached tool must be set to zero via a TARE function and then a known weight has to be lifted. This weight is entered into the sensor. From this point, the calibration is complete and all raised loads are displayed in kilograms or tonnes. The system can be used both in single and double acting hydraulic systems. The Precont TN is designed for harsh industrial environments and has dirt-insensitive optical keys and a user-friendly, largearea TFT display. Through this display both a plain textbased operation, and a weight indicator in various forms of representation are possible. The display options range from a large digital display with analog bar, to a pressure gauge with superimposed digital value. Even the colors of the display can be changed. The waterproof design of the sensor and the stainless steel housing also allow the use on open platform touts or e.g. i8n front of the cabin window right on the front loader console. The very high overload resistance of the sensor with a burst pressure of 1200bar and a measurement range of 250 bar ensures maximum safety. The digital Precont TN can also be used not only as a front loader or forklift scale. Conceivable applications are also in connection with the front or rear hydraulics of the tractor e.g. to determine the loading amount of the fertilizer spreader or the load capacity of the sprayer that are attached to the three-point linkage.

Advantages:
  • Easy self-installation and retrofitting
  • Cost-effectiveWhen calibrating only one weighing reference is necessary
  • Simple buoyancy of various tools
  • Large, backlit display 
  • Selection of the display in kg, t, or bar 
  • High accuracy 
  • Display formats can be selected as a pointer, bar or digital value 
  • Dust and waterproof, vibration-proof for use in harsh environments
  • Maintenance-free

  • A thin-film strain gauge is used as pressure sensor. The small dimensions of the measurement sensor ensures a good behaviour against pulsating measuring media and vibrating installations as well as a very good reproduceability and hysteresis and an overload resistance of up to 4-times the measurement range. Due to the high natural frequency of the metallic membrane also fast pressure changings could be measured. The versions Precont KS0 + KS1 has a process connection with an inside places separation membrane in high-grade steel in G1/2A or M20 x 1,5 acc. to DIN 16 288. This process connection is available in two version, with and without damping system.
  • The damping consists of an screw with a small slot that is placed at the medium side of the process connection. The variants Precont KS2, KS 3, KS 4 + KS 5 has a process connection with an front-flush separation membrane in high-grade steel in G 1/2A or M 20 x 1,5 for an seal in FPM or a metallic seal acc. to DIN 3852. The process connection is available with and without damping system. The damping consists of a choke that is placed at the measurement medium side. Ranges > 40 bar have an additional protection plate in front of the separation membrane. The version with damping should be used if an incompressible measurement medium with possible occuring pressure peaks over the measurement range should be measured. Pressure peaks can be produced e.g. by pumps, fast-closing vents, magnetic vents or controle cylinders. The pressure transmitter is conceived for advanced applications.
  • The very small dimensioned housing in high-grade steel is designed in protection class IP65.
