Differential Pressure Transmitter

SYDM24DP is capacitance type differential pressure transmitter, easy to install and use, safe and explosion-proof. Adopt advanced integrated circuit and SMT technology, high precision, small size, easy to adjust, good stability, strong ability of one-way overload protection, can be used in industry of power, metallurgy, petrochemical, pharmaceutical, instrument processing etc..

Applicable medium: liquid, gas, steam

Range: 0-40 MPa 

Output signal: 4-20mA, (Option: HART, 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)

 Range and zero point can be adjusted through the built-in adjusting screw nut or through HART communicator.

Positive migration:

The maximum positive migration value is the difference between the URL and the setting range.

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.

Vibration effect:  0.1% URL, 10~55 Hz, S=0.15mm, at any direction.

Power supply effect: <0.005% of the output range / V
