LD301 Differential Pressure Transmitter (D)
; Range: 1.25 to 50 kPa (2); Diaphragm
of 316L SS and Silicone Oil Fill Fluid (1); Flanges, Adapters and Drains of 316L SS (I);
Buna N O-Rings (B); Drains on the TOP (U); with Digital Indicator (1); Connections to
the Process 1/4 NPT (O); Electrical Connection 1/2 NPT (O); with Local Adjustment (1);
with Carbon Steel Bracket (1); without other Special Feature (O).
SERIAL NUMBER -
Three serial numbers are stored:
Circuit Number
- This number is unique to every main circuit board and cannot
be changed.
Sensor Number
- The serial number of the sensor connected to the
LD301
and
cannot be changed. This number is read from the sensor every time a new
sensor is inserted in the main board.
Transmitter Number -
the number that is writtenat the identification plate each
transmitter.
NOTE
The transmitter number must be changed whenever there is the main plate
change to avoid communication problems.
OP_COUNT -
Every time a change is made, there is an increment in the respective
change counter for each monitored variable, according to the following list. The
counter is cyclic, from 0 to 255. The monitored items are:
LRV/URV:
when any type of calibration is done.
Function:
when any change in the transference function is done, e.g., linear,
square root, const, table.
Trim_4mA:
when the current trim is done at 4mA.
Trim_20mA:
when the current trim is done at 20mA.
Trim_Zero/Lower:
when pressure trim is done at Zero or Lower Pressure.
Trim Upper Pressure:
when the trim is done at Upper Pressure.
TRM/PID:
when any change is made in the operation mode, i.e., from PID to
TRM or vice-versa.
Characterization:
when any change is made in any point of the pressure
characterization table in trim mode.
Write Protect:
when any change is made in the writing protection.
Multidrop:
when any change is made in the communication mode, for example,
multidrop or single transmitter.
Pswd/C-Level:
when any change is made in the password or the level
configuration.
Totalization:
when any change is made in the totalization, configuration or in the
reset.
