DIFFERENTIAL PRESSURE TRANSMITTER - USER GUIDE
e. Power Supply Effect
When power supply voltage is within the operating rating, zero and
span changes have less than ± 0.005 % of URL/V.
f. Mounting Position Effect
Installation error of less than 0.058 PSI (400 Pa) can be corrected by
PV = 0 reset.
g. Vibration Effects
Per IEC 61298-3 tests, < 0.1% URL
h. Ambient Temperature Effects
Within the range of -20 to 80 °C (-4 to 185 °F):
± (0.1 + 0.1 TD) % URL Accuracy °C
i. Static Pressure Effects
Effect on zero: ± 0.15 TD % URL / 1450 PSI (10 MPa)
Effect on full scale: ± 0.2 % URL / 1450 PSI (10 MPa)
j. Insulation Resistance
≥ 20 MΩ @, 100 Vdc
k. Damping Time
Total damping time constant: equal to the sum of damping time of
amplifier and sensor capsule
Damping time of amplifier: 0-100 S adjustable
Diaphragm capsule (isolated diaphragm and silicone oil filling)
damping time: ≤ 0.2 S
Startup after power off: ≤ 6 S
Normal services after data recovery: ≤ 31 S
l. Output Signal
Two wire 4-20 mA output with digital communications, linear or
square root output programmable, HART protocol is superimposed on
the 4-20mA signal.
m. Surge Protection
The transmitter has been tested to withstand a transient surge up to
2000 V (common mode) or 1000 V (normal mode) without damage
(Per IEC Std. 61000-4-5).
n. Weight
Net: 8.5 lbs. (3.9 kg) / Gross: 9.5 lbs. (4.3 kg)
