Pressure Transmitter

1)Technical parameter
 1.1 to subject: liquid, gas or vapour
 1.2 range ability: please contact us
 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, 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 amplifier: -25 ~ +90 degree
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 over-pressure:
     0 (absolute pressure) - 14Mpa, when range<6Mpa;
     0 (absolute pressure) -32Mpa, when range<20Mpa;
     0 (absolute pressure) - 52Mpa, when range<42Mpa
No damage for transmitter but may cause zero shift, suggest not to operate over-pressure, the max. pressure is 60Mpa for flange template.
 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;
      Note: for tpye LU-CGPS-1200 (1300), temperature affect is double times of above.
  2.4 Over-pressure affect:0.25% 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.
