ES2 Electronic Liquid Level Transmitter
EX-1845
Calibration Equipment Setup
To ensure specified accuracy during field calibration,
the equipment and setup used must conform to the
minimum requirements noted in this section.
Milliameter (multimeter)
: 3-1/2 digit minimum,
0.05% accuracy (internal resistance 20 Ohms or less)
Power Supply:
24 Volts DC (regulated); permissible
range is 14-40 Vdc
Pressure Indicator:
0.05% accuracy (corresponding
to transmitter nominal range)
0-5 psig
+ 0.0025 PSI (or 0.07 in. of water)
0-10 psig
+ 0.0050 PSI (or + 0.14 in. of water)
0-15 psig
+ 0.0075 PSI (or + 0.21 in. of water)
0-30 psig
+ 0.0150 PSI (or + 0.42 in. of water)
0-50 psig
+ 0.0250 PSI (or + 0.69 in. of water)
Pressure Regulator:
High precision fine thread adjust-
ment for stable air/gas pressure application
CAUTION: Some pressure regulators will allow a slight
pressure output even when completely adjusted to the
shut position. It is preferable to vent the transmitter to
atmosphere by disconnecting the pressure input to ensure
accurate zero setting of transmitter.
Test Shell Fixture
This pressure fixture is available in the following con-
figurations based on the mounting length of the ES2
transmitter. Threaded 1/8 NPT connections permit air/
gas pressure to be applied to the face of the transmitter
when seated within the test shell.
Part No.
