First , summary
YSZ series spread the pressure changer and adopt the most advanced
diffusion silicon pressure sensor in the world in order to detect
the component , it is the pressure changer of a kind of infant
industry that our factory developed.
The YSZ series pressure changer is advanced diffusion silicon +
computer tool instrument processing + temperature compensation +
analog signal treatment technology crystallization, broad quantity
Cheng its, many kinds of specification and standardized structure
can meet demands of user to the maximum extent .
Whether YSZ series apply industrial process control, in the
following place is it seem his original characteristic even more to
Require the place higher in precision;
Because has adopted the inside temperature compensation circuit ,
can apply to fluctuate in the large place in temperature ;
Can long run under the open-air environment ;
It is can be used in the dangerous place to select the originally
fitting type for use;
Can install it on the pipeline equipment directly , but does not
need to install the support .
Second, main technical indicator:
1.Measure the medium: Compatible with 316 stainless steel
crystallization medium any.
2.Measure the range:
To 0-7KPa of pressure (gauge outfit ) .......2.1MPa
Absolute pressure (vacuum ) 0-7KPa .......0.1MPa
Sealed pressure 0-3.5KPa ............35MPa
5.The voltage of the power and load characteristic: 24VDC Line two
system, can work in 12VDC when there is no load, the voltage 36VDC
of the largest power . Load ability is R =50 (E-12 ), E is the
voltage of the power .
6.Excessive pressure limit: 3 times of specified pressure ＆#118alue
in the Cheng range that it is quantity.
Use temperature: -40 - +85 degrees Centigrade
Store temperature: -40 - +125 degrees Centigrade
8.Stability: For quantity not every for Cheng,drift about not
smaller than by 0.2%ing of ±s (F.S) it /the annual
9.Temperature is influencedTemperature error not big most where
change cause on it is at 0-70 degrees Centigrade for 0.75%FS /the
10.The seat influencesChanger wanton position install very, zero
any it drifts about to be can through is it dispel to return to
zero, quantity one is not influenced .
11.The radio frequency interferes influencing ; Frequency 27-100MHZ
intensity of field interference of 30V/m to radio frequency, output
error smaller than 0.1%, quantity of Cheng.
12.Vibration is influencedTo frequency being 10-500HZ, acceleration
is it smaller than 0.1%, quantity of Cheng to influence all for
30m/s2 vibration their.
13.Crossing the range influences: Bear 1.5 specified pressure after
resuming , is it smaller than 0.04%, quantity of Cheng to influence
14.The voltage of the power is influencedWithin the range of
working voltage, every change 1V output change smaller than 0.005%,
quantity of Cheng.
15.Quantity one is moved5:1
16.Check the humidity: 0-95%RH
17.Dielectric strength: Able to bear the situation of keeping 500V
and has not punctured flashing to leave out the phenomenon for one
18.Start-up time: Not greater than 2 seconds , does not need it in
19.The structure and material
Outer coverMould die casting aluminium
Outer cover spraying: Oxygen spraying of the ring
The outside is protected: Accord with IECIP65
20.Medium contacting department material with examining
The course links one: Stainless steel 1Cr18N19Ti
