Product Description

Technical Data:

● Applicable medium: liquid, gas, steam
● DP Range option: -0.1 ~ 1Kpa,  0 -1~ 6Kpa,  0 -6~ 40Kpa,  0 -40~ 250Kpa,  0 -0.16~ 1Mpa,  0 -0.4~ 2.5Mpa,  0 -1.6~ 10Mpa
● Output signal: 4-20mA (Option: HART [belong to HART Communication Foundation], Square root output), Power supply: 12 ~ 45VDC, Generally 24VDC. Load: RL= (Vs – 12V) / 0.023A ( RL is Maximum load, ≤ 600 Ω, Vs is power supply voltage)sydm24 resistance load

● Range and zero point can be adjusted through the built-in adjusting screw nut or through HART communicator.
● Positive and negative migration:
The maximum positive migration is the difference between the URL (Instrument’s upper range limit) and the setting range, the maximum negative migration is URL.
● Fault alarm: The fault is detected by the self-diagnosis program. It will alarm when the analog output is higher than 22mA or lower than 3.9mA.
● Operation temperature:
-40 ~ 85℃ (analog transmitter), -10 ~ 80℃ (smart transmitter)
-40 ~ 104℃ (sensor: Silicone oil filling), -184 ~ 71℃ (sensor: Inert oil filling)
Flange type remote seal (fill ordinary silicone oil): -40 ~ 150 ℃
Flange type remote seal (fill high temp. silicone oil): 15 ~ 315 ℃
● Storage temperature: 40 ~ 50℃
● Startup time: < 2s
● Volumetric absorption: < 0.16 cm3
● Damping: Adjustable in range 0 ~ 16 s
● Accuracy: 0.2%FS (standard configuration) , 0.1%FS (option)
● Stability: free of maintain within one year
● Temperature effect:
Total error varies <±0.3 URL every 10℃ for the range code 4,5, 6, 7, 8
The total error is doubled every 10℃ for the other range.
● Static pressure effect:
DP transmitter: For static pressure 14 Mpa, ±0.25% URL or ±0.5% range code 3.
For static pressure 32 Mpa, ±0.2% URL. Under process pressure, adjust zero point for correction.
● Vibration effect: 0.1% URL, 10~55 Hz, S=0.15mm, at any direction.
● Power supply effect: < 0.005% of the output range / V
