Hydrostatic probe SDS-10 It is intended for smooth measurement of the medium level in tanks, pumping stations, channels and other places with high sedimentation. The liquid level transducer is based on the principle that the measured liquid static pressure is proportional to the height of the liquid in the tank.
The product uses the piezorezstant effect of sensitive ceramic elements to convert static pressure to an electrical signal, which is transmitted to a dedicated digital circuit to: its strengthening, linear compensation, counteracting disturbances, anti -redemption and other signal processing. The result is obtaining a signal with the parameters of a standard industry signal, e.g. 4-20 mA, 0-10 V, etc.
Thanks to the standardized electrical signal, detailed information about the medium level in the tank is obtained, which is used to read parameters and/or levels of levels, e.g. switching on or switching off: pumps, slopes, valves, etc.
Destiny: Chemical plants, sewage treatment plants, various acid liquids and gases other than hydrochocci, dams, rivers and other places with lots of sediments.
Characteristics:
- Much greater measurement accuracy and options for other measuring methods such as conductometric probes or swimming switches,
- A large measuring range when it comes to the depth of the tank and liquid level (0-10 m H2O) and insensitivity to temperature changes (-20 ° C–+80 ° C).
- No moving elements, such as a bending cable in swimmers, which can lead to a float suspension or damage as a result of essay,
- Much lower susceptibility to clogging or preparing with adhesive and permanent sewage fractions than in the case of conductometric probes,
- Permanent working conditions, resulting from the need to constantly immerse the probe in the medium,
- Easy and low installation level, the probe hangs on its own cable only a few cm above the bottom,
- High resistance to a variable and aggressive sewage environment, in ordinary swimmers, they steal, stiff and damage the cables over time, and conductometric probes coincide with impurities or raid and lose their conductivity conditions,
- Levels read through a converter can be easily modified in controllers, in the case of conductometric probes and FloatThis must be interfered with their installation in the tank.
- Warranty and post -warranty service
- 24 -month warranty
