ES2 Electronic Liquid Level Transmitter
EX-1845
KING-GAGE ES2
Level Transmitter
Two-wire transmitter provides a direct 4-20 mAdc analog electronic output
signal. The ES2 transmitter is designed specifically for hydrostatic pressure
measurement for liquid level gauging.
Specifications
Pressure Ranges
0-5, 0-10, 0-15, 0-30, 0-50 psig
(Gage pressure measured relative to ambient atmospheric pressure.)
Accuracy
Less than ± 0.20% FS
Includes linearity, hysteresis, non-repeatability errors.
Pressure Media
Gas or Liquids compatible with 316 stainless steel (diaphragm);
silicone rubber (O-ring). All other wetted parts 316L.
Electrical
Input (excitation): 14-40 Vdc
Output (mAdc): 4-20 milliamperes
Span Adjustment Range
Transmitter adjustment turndown is 3:1 for the 0–15, 0–30, 0–50 psig nominal ranges.
Nominal
Minimum Range of Adjustment
0–5 psig
0–3 psig
0–83 in. thru 0–138 in. water / 0–2.1 m thru 0–3.5 m water
0–10 psig 0–3 psig
0–83 in. thru 0–277 in. water / 0–2.1 m thru 0–7.0 m water
0–15 psig 0–3 psig
0–83 in. thru 0–415 in. water / 0–2.1 m thru 0–10.5 m water
0–30 psig 0–10 psig 0–277 in. thru 0–830 in. water / 0–7.0 m thru 0–21.0 m water
0–50 psig 0–15 psig 0–415 in. thru 0–1384 in. water / 0–10.5 m thru 0–35.1 m water
Operating Limit (Maximum Pressure)
Pressure above 300% nominal range (overrange) will result in damage to the transmitter
(200% may cause a shift in calibration).
Non-Repeatability (Worst Case)
Less than 0.02% FS
Operating Temperature Range
0°F to 175°F/ -17°C to 79°C
