product description
OMNI: evaluation electronic with analog output, switching function and display
General information:
The gearwheel flow meter VHZ measures the flow according to the volumetric principle, where a pair of gearwheels is moved proportional to the flow rate. The movement of the gearwheels is measured through the closed housing wall by a sensor. The devices are suitable for viscous, fluid, self-lubricating media, as well as for aqueous fluids such as soaps, pasts, emulsions etc. which have a non-abrasive character. Because of the volumetric operation, the devices are almost completely independent of viscosity.
The OMNI transmitter on the sensor has a graphical, backlit LCD display which is clearly readable, both in the dark and in bright sunlight. The graphics display allows the indication of measured values and parameters in a clearly understandable form.
The measured values are displayed with 4 digits, together with their physical unit which may also be modified by the user. The electronics have an analog output (4 mA to 20 mA or 0 V to 10 V) and two switching outputs, which can be used as limit switches for minimum or maximum monitoring or as two-point controllers.
The switching outputs are designed as a push-pull drivers, and therefore can be used both as PNP or NPN outputs. The exceeding of limit values is signalled by a red LED which is visible over long distances and by a cleartext message on the display. The housing made of stainless steel has a hardened, scratchproof mineral glass pane. It is operated via a programming ing ring that is fitted with a magnet. Therefore housing cutouts for the purpose of operating elements are not necessary and the tightness of the housing is permanently ensured.
By turning the ring to right or left, you may modify the parameters (e.g. switching point, hysteresis...). To protect from unintended programming, it can be taken off, turned by 180° and replaced afterwards, or it can be removed completely, thus acting as a key.
