A money of a stock, we don't have a ceramic core as diffusion silicon core.
What price is what the core body
What is the diffusion of silicon core?
The diffusion silicon sensor: the basic principle is to use the piezoresistiveeffect of semiconductor and micro machining technology, in particular to the crystal silicon wafer, made of lithography, diffusion semiconductor process a Wheatstone bridge, the formation of sensitive membrane, when subjected to external force produced by the micro strain, change of resistivity, the bridge arm resistance to change (larger to smaller one) in the excitation voltage signal output by computer, temperature compensation, laser trimming, signal amplification and processing method and assembly detection, strict calibration process, produce pressure transmitter with standard output signals.
Ceramic sensor:
(stability is not good anti-corrosion liquid gas diffusion silicon).
Ceramic sensor is dry sensor, process pressure directly on the ceramic membrane is strong, the substrate electrode and membrane electrodecan detect the change in capacitance associated with stress,measurement range depends on the thickness of the ceramicdiaphragm. The self diagnosis function of broken. Guarantee againstovervoltage capacity up to 40 times the normal pressure. High purity of 99.9% ceramic, has the same and resistance to chemical corrosion of Hastelloy alloy. Applicable for vacuum applications. The second chamberis used to enhance the mechanical strength, prevent the damage caused by the sensor medium leakage.
Flat membrane type - need to order (all range can be customized)
An overview.
KSTT801 diffused silicon piezoresistive pressure sensor is a kind of high performance liquid level transmitter designed for field use in bad environment. Its appearance is delicate integration all stainless steel structure, convenient installation, and has the advantages of anti vibration and impact strength, high accuracy, good stability,measurement is widely used in petroleum, chemical, metallurgy, electric power, water conservancy, food, pharmaceutical industry pressure,liquid level and process control.
The working principle of two.
Based on the piezoresistive effect of silicon, monocrystalline silicon as substrate, according to the specific orientation, using micromachining techniques form the elastic element of advanced, integrated circuittechnology in its proper position to form four equivalent strain resistance, form a Wheatstone bridge, applying a constant voltage to the bridge (flow), when the pressure (differential pressure) the elasticelement, the output corresponding to the pressure into a voltage signalproportional to, through the electronic circuit to voltage signal amplification into three wire 0-5V output.
Three technical instructions.
Range: 0 - 2Kpa - 60Mpa (Quan Liangcheng)
Output: 0-5V three wire system
0-10V three wire system
4-20MA two-wire system
Power supply: 12 - 36VDC 24VDC
Precision grade: 0.25%FS
Long term stability: ≤ ± 0.2%FS/
Temperature range: -40 - 85 ℃
The humidity of the environment: 90%RH. "
Environment temperature: -10 ℃ - 85 ℃
Overload pressure: 120%FS
Explosion proof pressure gauge
If necessary please click below link transmitter explosion-proof type pressure gauge
Electrical connection four.
Junction box for a standard HIRSCHMANN connector, pin 3 is connected to the load, the grounding end connected to the power supply negative.The electrical connection diagram as follows:
Installation design
Five. The zero adjustment and full scale
Casing joints and stainless steel screw off HIRSCHMANN, you can see the circuit board increase zero potentiometer W201 and fullpotentiometer W203
External standard ammeter (voltage meter) (more than 0.2) can be adjusted, the steps are as follows:
1 the pressure is equal to zero, zero potentiometer, the standard voltageindicator for 0V; (0V) (current 4MA)
2 full range pressure, full adjusting potentiometer, the standard voltageindicator for 5V; (10V) (current 20MA)
The 3 chapter 1.2 steps repeated two or three times, until it meets the requirements.

Note seven.
1 where the delivery of products with the product certification and instructions for use, including product number, technical parameters,wiring diagram, the factory date, please carefully check, so as to avoid the wrong.
2 should be installed according to the way of connection and thread type, check the site interface and interface products. If the thread interface, should slow tightening, pay attention to sealing, not the torqueapplied directly to the transmitter housing, can only be added in the sixpressure interface.
The 3 wiring shall be in strict accordance with our instructions require.
4 this product line can instrument for precise, forbid disassemble,collision, dropping, throwing up or use sharp instruments poke pressurehole.
Can work for 5 transmitter power, but warm after 30 minutes output stability.
6 use if unusual, should turn off the power supply, to stop using, check,or directly to my company technical department.
The 7 transport, storage should recovery package, stored in a cool, dry,ventilated warehouse.
