Application

The transmitters PRE-28.Modbus have two operating modes, configuration mode and Modbus mode. The configuration mode

is used for changing settings and detailed diagnostics of the transmitter. In this mode you can also activate a current loop

compatible with a 4-20 mA current output.

Technical data

Accuracy Ł ±0,1% of calibrated range

Long-term stability Ł accuracy for 3 years

(for the basic range)

Thermal error < ±0,08% (FSO) / 10°C

max. ±0,3% (FSO) in the whole compensation range

Thermal compensation range -25...80°C

Zero shift error for static pressure

0,01% (FSO) / 10 bar for ranges no. 3, 4, 5, 6, 7

0,03% (FSO) / 10 bar for range no. 8

0,06% (FSO) / 10 bar for ranges no. 1, 2

Zeroing the transmitter in conditions of static pressure can eliminate this error.

Error due to supply voltage changes 0.002% (FSO) / V
