Signal type

Current (2-wire):  4 ... 20 mA

Current (3-wire): 0 ... 20 mA

Voltage (3-wire):

      DC 0 ... 10 V

      DC 0 ... 5 V

      Other output signals on request

Depending on the signal type the following loads apply:

      Current (2-wire) ≤ (power supply - 10 V) / 0.02 A

      Current (3-wire) ≤ (power supply - 3 V) / 0.02 A

      Voltage (3-wire) > max. output signal / 1 mA

Voltage supply: The power supply depends on the selected output signal

      4 ... 20 mA, 2-wire DC 10 ... 30 V

      0 ... 20 mA, 3-wire DC 10 ... 30 V

      DC 0 ... 10 V, 3-wire DC 14 ... 30 V

      DC 0 ... 5 V, 3-wire DC 10 ... 30 V

Temperature error in rated temperature range

Rated temperature range: 32 ... 176 °F (0 ... 80 °C)

Mean temperature coefficient of zero point:

      Measuring range > 0.25 bar ≤ 0.2 % of span/10 K

      Measuring range ≤ 0.25 bar < 0.4 % of span/10 K
