Fast, digitally compensated pressure transmitters with analog output
The sensor signal is measured 400 times per second with a highly precise A/D converter (16bit). After each measurement, the exact pressure value is calculated, thereby eliminating
the linearity and temperature errors. The analog output signal is updated via the D/A converter
Analog Output:
Voltage output: 0 – 10 V
Current output (2-wire): 4 – 20 mA
The outputs are protected against reverse polarity and short-circuit.
Digital Interface
In addition to the analog signal output, these pressure transmitters offer a digital, bus-capable interface, offering the following features;
Read-out of the pressure and temperature values
User adjustment of zero and gain
Scaling of the analog output to other pressure ranges or units
Configuration settings
Read-out of information, such as serial number, compensated pressure and temperature ranges
Two wire RS485 half-duplex with 9,600 baud or 115,200 baud
