1.3 output: 4-20mA DC
1.4 power: 24VDC, it can be 12VDC if non-load, max. is 45VDC
1.5 positive and negative transfer: up and low may not exceed the range limit after positive and negative transfer shifting, whatever the output is.
Max. positive transfer: 500% of the min. span.
Max. negative transfer:600% of the min.span.
1.6 Temperature:

temperature of operating for sensor: -40 ~ +104 degree
1.7 relative humidity: 0 ~ 100%
1.8 sensor capacity changes: <0.16cm^3
1.9 indicate meter (field): scale gauge length: 30mm; grade: 2.5
2.0 isolating explosion: ds II BT5, Intrinsically-safety: ia II CT5
2.1 span and zero: external continually adjusted
2.2 static-pressure and over-pressure limit: if add 0 (absolute pressure)-14Mpa to any one side of the transmitter, no damage for transmitter.
2.3 static-pressure affect:
2.3.1 zero error:+/-0.5% of max.range,when operating pressure is 14Mpa.
2.3.2 range error: is a system error,can be calibrated.
2.3 damp:continually adjusted when time constant is between 0.2-1.67s
2.4 setting time:2s

2) Performace Index (Note: test under the condition of none shift, max. range status of sensor, 316L stainless isolating

disaphargm and other standard condition)
2.1 Accuracy:+/-0.25% of the span, including the synthesize errors of linear, change-difference and repeat.
2.2 Stability:+/-0.25% of max. range (12 months)
2.3 Temperature affect:
     Zero error:+/-0.5% / 55 degree, zero & range errors:+/-1.0% / 55 degree, when max. range;
     Zero error:+/-3.0% / 55 degree, zero & range errors:+/-3.5% / 55 degree, when min. range;
2.4 Over-pressure affect:+/-1% to +/-3% of max. range (according to permitted over-loads for different ranges)
2.5 Vibration affect:+/-0.05% / g of the max. range, when 200Hz, any axis up.
2.6 Power affect:<0.005% / V of output range
2.7 Load affect:none affect when voltage>12VDC input to the transmitter.
2.8 Mounting position affect:may cause zero error max.0.24Kpa, but can be calibrated,none affect for range.
