JCGP Gauge Pressure Transmitter
JCGP type (smart) pressure transmitter has high overpressure strength and good stability.
Input span: 0~0.25kPa, 0~10Mpa, 0~40Mpa.
Service medium: liquid, gas and steam
Overpressure limit:
Span is the impose below 6Mpa: 0 (absolute pressure) ~14MPA
Span is the impose of 20Mpa: 0 (absolute pressure) ~32MPA
Span is the impose of 40Mpa: 0 (absolute pressure) ~52MPA
Flange can afford 60MPa pressure.

Techncal Parameter
● Service: liquid, gas and steam
● Measuring range : 0~0.06 kPa to 0~40Mpa
● Output signal : 4~20mA DC (four-wire 220V AC power supply, 0~10mA DC output for special)
● Power supply : 12~45V DC, generally 24V DC
● Features of loading: relation equation of loading impedance RL and power voltage
Vs: RL <= 50(Vs-12)
● Indicator : pointer-type linearity indication 0~100% scale mark or LCD indicator, LED indicator.
● Explosion proof : a. explosion isolation d II CT6
b. intrinsically safe ia II CT6
● Positive and negative shifts : after positive and negative shifts of zero absolute values of upper-and-lower-limit values of span and measuring range not exceed 100% of upper limit of measuring range.( smart type : turn down ratio 20:1, 40:1)
Maximum positive shift is 500% of minimum adjusting span; maximum negative shift is 600% of minimum adjusting span.
● Temperature range: amplifier operation temperature range: -29 ~ +93C
(LT type: -25 ~ +70C); measuring component of fill silicone oil: -40 ~ +104C
flange type transmitter fill hi-temperature silicone oil: -20 ~ +315C normal silicone oil: -40 ~ +149C
● Static pressure : 4, 10, 25, 32Mpa
● Humidity : relative humidity 0~100%
● Volume absorption : < 0.16cm3
● Damping (phase step response) : For silicone oil, generally between 0.2s and1.67s, continuous and adjustable
(no shift, under standard operation conditions, fill silicone oil, 316 SS diaphragm)
● Accuracy class: +/-0.25%, +/-0.5% (smart type: +/-0.1%, +/-0.075%)
● Dead zone: no (<=0.1%)
● Stability : within 6 months not beyond absolute value of basic error of maximum span
● Vibration effect: on a random ax upward, at vibration frequency of 200 Hz, error +/-5%/g of upper limit of measuring range.
● Power effect : < 0.005%/V of output span
● Loading effect : no effect from loading at stable power
● Effect of installation position : at most 0.24kPa of zero error, no effect on span
