1.       technical performance

●       to subject: liquid, gas or vapour

●       range ability: 

 

 

●       output: 4-20mA DC

●       power: 24VDC, it may be 12VDC if non-load, max. is 45VDC

●       load characteristic:

●       positive & negative transfer: up and low may not exceed the range limit after positive & negative transfer, whatever the output is.

Max. positive transfer: 500% of the min. span.

Max. negative transfer: 600% of the min. span.

●       Temperature:

temperature of operating for amplifier: -25℃ ～ +90℃

temperature of operating for sensor:  -40℃ ～ +104℃

●       Relative humidity: 0~100%

●       Sensor capacity changes: <0.16cm³

●       Indicate meter (field): scale gauge length: 30mm,

grade: 2.5

●       Isolating explosion: ds Ⅱ BT5,   Intrinsically-safety: ia Ⅱ CT5

●       Span & Zero: external continually adjusted

●       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.

●       Damp: continually adjusted when time constant is between 0.2~1.67 seconds.

●       Settling time: 2s,

 

2. performance index (note: test under the condition of none shift, max. range status of sensor, 316L stainless isolating diaphragm and other standard condition)

●       Accuracy: ±0.25% of the span, including the synthesize errors of linear,     change-difference and repeat.

●       Stability: ±0.25% of max. range (12 months)

 

●       Temperature affect:

zero error:±0.5% / 55℃,  zero & range errors:±1.0% / 55℃, when max. range;

zero error:±3.0% / 55℃,  zero & range errors:±3.5% / 55℃, when min. range;

        note: for type LU-CGPS-1200 (1300), temperature affect is double times of above

●        Over-pressure affect: ±0.25% of max. range (according to permitted over-loads for     different ranges)

●       vibration affect: ±0.05% / g of the max. range, when 200Hz, any axis up.

●       Power affect: <0.005%/V of output range

●       Load affect: none affect when voltage >12VDC input to the transmitter.

●       Mounting position affect: may cause zero error max. 0.24Kpa, but can be calibrated,   none affect for range
