PW900智能壓力調(diào)節(jié)器是我公司研制生產(chǎn)的新型工業(yè)自動(dòng)控制儀表，該產(chǎn)品吸收了國(guó)外九十年代同類產(chǎn)品的優(yōu)點(diǎn)，同時(shí)還具有它獨(dú)自的特點(diǎn)，特別適用于高溫熔體壓力的測(cè)量與控制，及電網(wǎng)波動(dòng)較大的場(chǎng)合。該產(chǎn)品外形美觀、功能齊全、極好的抗干擾性能使系統(tǒng)可靠工作。
該表采用雙層四位數(shù)碼管分別顯示實(shí)際壓力值和設(shè)定值；輸出窗口單排條碼顯示輸出功率，具有壓力上、下限報(bào)警，可由繼電器觸點(diǎn)輸出、電壓脈沖輸出、雙向可控制硅驅(qū)動(dòng)觸發(fā)器輸出；恒流（或恒壓）輸出，全自動(dòng)面板調(diào)試程序，使系統(tǒng)校準(zhǔn)只需輕輕一按；該表采用三種抗干擾措施，使調(diào)節(jié)器可靠工作；第一、采用光電隔離電路使輸入與微處理器隔離，微處理器與輸出隔離，電源與輸入、微處理器、輸出隔離；第二、采用軟件抗干擾措施，使軟件可靠工作；第三、采用硬件程序監(jiān)視系統(tǒng)，使系統(tǒng)程序受到干擾后能自動(dòng)恢復(fù)正常工作。經(jīng)實(shí)踐表明采用以上抗干擾措施可使系統(tǒng)軟件有很高的可靠性，確保系統(tǒng)工作穩(wěn)定、可靠，輸出功率為PID和模糊控制相結(jié)合，使手動(dòng)自動(dòng)無(wú)擾動(dòng)切換，同時(shí)功率輸出值為步進(jìn)輸出。
該產(chǎn)品廣泛應(yīng)用于石油、化纖、塑料行業(yè)對(duì)高溫熔體壓力的測(cè)量與控制。

PW 900 series of intelligent temp and pressure digital instruments are the products of our company. We are the initial designers and vendors of the double-function digital instruments. PW series consist of PW300, PW300dual, PW600, PW800 and PW900. They incorporate the advantages of the same products from foreign countries in 1990s, as well as new features are added. Actually, they are quite suitable for measurement and control at one point for temp and pressure. PW series are good-looking and of excellent EMC performance.



New features:

Two-layer digital LEDs with four-bit for each layer display actual pressure value and temp value;
Pressure and temp alarms can be easily set;
The output can be generated by relay, voltage pulse or silicon via constant voltage or constant current;
System operation is controlled by the key panel;
Calibration can be easily completed just by pressing CAL key on the key panel.


Three new technical methods are introduced to enhance the EMC performance:

Photoelectric modules insulate the microprocessor from input and output interface;
New anti-jamming methods are used in the system program;
A hardware monitor runs all the time, which can reset the system to normal operation from abnormal operation after distortion.
