Product Detail

PT-DP003 capacitive differential pressure transmitter can precision measurement for liquid
level and density of various containers. Transmitter is fixed to the container with pipe flange.
Fit to measure medium of high temperature、high viscosity and easy to subside or strong
corrosive。Membrane subassembly have plane and plug-in types.flange size:3inch and 4inch;
pressure grade: 50Ib and 300Ib. The membrane can select 316 stainless steel, Hastelloy or
tantalum according to measure medium.

Output	Analog output: two wire 4～20mADC Digital output: two wire 4～20mADC and variable digital signal in accordance with HART AGREEMENT.
Power	supply voltage 12.5～45VDC
Limit load	Max load resistor Rmax in loop decided by the supply voltage,see the below drawing. HART AGREEMENT require the load resistor not less than 250Ω,not more than 600Ω
Communication distance	Max. 1.5Km, multi-address communication can connect 15 smart transmitters Max.
Output display	4 digital display,5 digit LCD display, pointer type.
Marking	ExiaII CT5 ;explosion-proof isolation type
Zero offset	can positive offset or negative offset,but can not overstep the utmost value
Temperature	environment temperature:-40～85℃ (When choose LCD : -20～70℃) Medium temperature: -40～104℃
Static pressure and one side overload	150Ib flange：3.45Kpa（absolute）～1.89MPa（37℃） 300Ib flange：3.45Kpa（absolute）～4.9MPa（37℃）
Relative humidity	5～98%RH
Startup time	less than 5 sec
Capability change	less than 0.16cm3
Damp adjust	0.20～25sec.
Malfunction alarming	If appear malfunction, automatism diagnose function will output 3.9 or 21.0mA
Protection	To avoid the datas are modified random,can utilize software or protect switch lock the memory data.

Reference condition	zero is the lower limit and not offset, temperature 25℃, Atmospheric pressure, 24VDC power, silicon oil , diaphragm 316L, data adjust range the same as the up and lower limit of the range
Accuracy	±0.1%, adjust range ≥0.1URL ±[0.05+(0.005URL/span)]%, adjust range 0.025URL~0.1URL ±[0.01+(0.006URL/span)]%, adjust range 0.01URL~ 0.025URL Note: accuracy have include the influence of linearity,hysteresis and repeatability
Stability	±0.1%URL/year
Tem. influence	±（0.05%URL+0.15%span）/20℃
Static pressure influence	zero error 0.1URL/6.9Mpa
Libration effect	withstand frequency 200Hz at any direction, arouse error ±0.05%URL
Power influence	0.005%/V
Load influence	no load influence
Install position influence	about 250Pa zero offset, can be eliminate via calibration,no range influence
RF interference	drift is ±0.1%span in the condition of 30-1000MHz frequency and the most field intensity 10V/m
