HYDROSTATIC LEVEL METER Highly Precise Level Pressure Transmitters Digitally compensated / Rangeable / Digital and analog output These pressure transmitters are designed for level measurements where the highest accuracy is required. Digital Output of Transmitter This Series is based on the stable, piezoresisitive transducer and a micro-processor electronics with integrated 16 bit A/D converter. Temperature dependencies and non-linearities of the sensor are mathematically compensated.With the READ30 software and the RIELS® cable K-107, the calculated pressure can be displayed on a Palmtop, Laptop or PC. The READ30 software also allows the recording of pressure signals and the graphic display on the PC. Up to 128 transmitters can be hooked together to a Bus-system. Tutti i dati ed i contenuti di questa scheda sono di proprietà esclusiva di Riels Instruments Transmitter with Analog Output The micro-processor integrates a D/A converter of 16 bit for analog signal outputs of 4…20 mA or 0…10 V. The output rate is 100 Hz (adjustable). The digital output is available on all transmitters with analog output. Programming With the RIELS® software READ30 and PROG30, a RS485 converter (i.e. K-102, K-104 or K-107 from RIELS®) and a PC (Laptop), the pressure can be displayed, the units changed, a new gain or zero set. The analog output can be set to any range within the compensated range The level transmitters are available in two different versions: • PAA-36 X W Absolute Pressure, Zero at Vacuum This probe is applied when the atmospheric pressure is measured by a separate barometer nd when the water level is calculated as the difference between the absolute value and the ambient pressure. • PR-36 X W Relative Pressure, Zero at ambient Pressure This probe is fitted with durable cable with an integral vent tube to the atmosphere. These level transmitters can be subject to internal condensation caused by installations in cold water on warm, humid days. If the reference tube is not terminated in a warm, dry enclosure, RIELS® recommends the use of a purpose built cartridge filled with a silica gel which is fitted at the end of the reference tube. Specifications PR-36 X W PAA-36 X W Overpressure Output Supply (U) Accuracy, Error Band1) (0...50 °C) Standard Pressure Ranges (FS) and Overpressure in Bar Note The ranges 100, 200 or 500 mbar are realized with the 1 bar transmitter. Accuracy for these ranges is ± 1 mbar (0…50 °C) All intermediate ranges for the analog output are realizable with no surcharge by spreading the standard ranges. Option: Adjustment directly to intermediate ranges against surcharge. 1) Linearity + Hysteresis + Repeatability + Temp. Coeff. + Zero + Span Tolerance
