МП3/ЖК Current signal 4-20 with a HART-based digital signal with an indicator (liquid-crystal indication) for all climatic categories

Control and indication elements, configuration variants

The indicator is installed into the electronic converter body frame in the gauges with version code MP3 (see the Table 14). In the pressure measurement mode the indicator displays the measured pressure value in the pre-set measurement units: kPa, MPa, mm of mercury, mmAq, kgf/cm2, kgf/m2, bar, Pa, warnings or diagnostic messages.

ЭнИ-100 adjustment is conducted for:

  • versions МП3 и МП3/ЖК — with the help of a built-in keyboard, with the application of a HART-communicator or HART-moden and computer;
  • versions МП2 — only with the application of a HART-communicator/HART-modem and computer.

  • — «4-20» — linear-increasing dependence;
  • — «20-4» — linear-decreasing dependence;

6 — status field — it is intended to indicate the presence of the following types of sensor configuration locks:

  • — «О» — lock changing settings from the keypad and HART Protocol;
  • — «Н» — lock change the settings for the HART Protocol;
  • — «М» — lock the correction of zero with a magnetic button;

7 — барограмма — display the current measured pressure value in relative value according to the set upper (100 %) and lower (0 %) limits of measurement;
8 — measured value — display the current measured pressure value in numerical form according to the set units;
9 — indication of the selected unit — the main units of pressure measurement that are most commonly used in the pressure sensors produced ЭнИ-100: kgf/cm2, Pa, kPa, MPa;
10 — text string — text string displays additional unit values that cannot be displayed in the Units field (for example, mm Hg). art., mm of water. kgf/m2, bar), also serves to display the menu of the pressure sensor, navigation through which is made using a four-button keyboard.

The gauge configuration menu allows one to set the value for upper and lower limits of pressure measurement, correct «нуль» from the installation position and static pressure, change measurement units, output signal conversion characteristics (linear or root-extracting), damping time, calibrate the gauge against the reference pressure, calibrate current output.

The data exchange with a converter through a HART-protocol allows gauge identification, output parameter configuration, reading the measured pressure value, output current and output signal in %, output current setting, analog output signal calibration.

The digital signal from the gauges ЭнИ-100 can be accepted and processed by any HART-device (HART-communicator or HART-modem and computer) supporting the HART-protocol.

There is an opportunity to correct «zero» with the help of external magnetic key.
