PT500-540 TTL數(shù)字壓力變送器使用注意事項(xiàng)
產(chǎn)品供電3.6VDC（范圍：3-5VDC）；
嚴(yán)禁使用硬物（如：螺絲刀、手指、鐵釘?shù)龋┤ナ沟脡盒倔w受壓力測(cè)量輸出；
電源和信號(hào)線按訂購(gòu)產(chǎn)品規(guī)格要求，正確接線；
產(chǎn)品安裝時(shí)，受力部位為“過(guò)程連接六方扳手位”，扳手規(guī)格與六方相對(duì)應(yīng)；
嚴(yán)禁被測(cè)系統(tǒng)的介質(zhì)溫度、壓力量程、激勵(lì)電壓超過(guò)變送器的額定使用范圍；
注意保護(hù)變送器引出電纜，現(xiàn)場(chǎng)使用跨度過(guò)大時(shí)，建議使用金屬管保護(hù)或架空；
壓力變送器屬精密計(jì)量?jī)x器，切勿強(qiáng)加沖擊、摔打，以免損壞芯體；

Precautions for PT500-540 TTL digital pressure transmitter
Product power supply 3.6vdc (range: 3-5vdc);
It is strictly prohibited to use hard objects (such as screwdriver, finger, iron nail, etc.) to make the pressure core body under pressure measurement output;
The power and signal wires shall be correctly wired according to the specifications of the ordered products;
When the product is installed, the stressed part is "process connection hexagon wrench position", and the wrench specification corresponds to hexagon;
It is strictly prohibited that the medium temperature, pressure range and excitation voltage of the tested system exceed the rated use range of the transmitter;
Pay attention to protect the outgoing cable of the transmitter. When the span is too large on site, it is recommended to use metal pipe for protection or overhead;
The pressure transmitter is a precision measuring instrument, do not impose impact or smash to avoid damaging the core;
The product is installed in a ventilated, dry and non corrosive environment, and installed in the open with protective devices to avoid direct sunlight;
