Equivalent Circuit
The Type i2P-100 equivalent circuit is a series
circuit consisting of a constant voltage drop
(battery) of approximately 4 V dc and a total
resistance of 40 ohms. Input is shunted by two
6.8 V zener diodes (see figure 9).
Supply Pressure

Recommended: 0.3 bar (5 psi) higher than upper
range limit of output signal
Maximum: 3.4 bar (50 psig)
Medium: Air or Natural Gas

Performance
(3)
Reference Accuracy: ±1.0% of full scale output
span; includes combined effects of hysteresis,
linearity, and deadband
Independent Linearity

: ±0.75% of full scale
output span
Hysteresis
(1)
: 0.4% of full scale output span
Frequency Response
(1)
: Gain is attenuated 3 dB
at 6 Hz with transducer output signal piped to a
typical instrument input
Temperature Effect: ±0.14% per degrees
Celsius (±0.75% per degrees Fahrenheit) of span
Supply Pressure Effect: 0.2% of full scale output
span per bar supply pressure change (0.2% of
full scale output span per psi supply pressure
change)
Vibration Effect: Less than 1% of full scale
output span when tested to SAMA PMC 31.1,
