Dwyer 液用差壓變送器 629C系列
629C系列濕/濕差壓變送器，以0.5％的精度監(jiān)測空氣及兼容氣體和液體的壓差。該設(shè)計采用雙壓力傳感器將壓力變化轉(zhuǎn)換為標(biāo)準(zhǔn)的4至20 mA輸出信號或現(xiàn)場可選電壓。內(nèi)部體積小，移動部件少，因此具有出色的響應(yīng)和可靠性。 在頂蓋下方可以輕松接觸到接線盒和零點(diǎn)調(diào)整按鈕。 629C系列差壓變送器的設(shè)計符合NEMA 4X（IP66）結(jié)構(gòu)。

The Series 629C Wet/Wet Differential Pressure Transmitter monitors differential pressure of air and compatible gases and liquids with 0.5% accuracy. The design employs dual pressure sensors converting pressure changes into a standard 4 to 20 mA output signal or field selectable voltage. Small internal volume and minimal moving parts result in exceptional response and reliability. The terminal block, as well as a zero adjustment button, are easily accessed under the top cover.
The Series 629C, with the optional factory installed remote sensors, are connected to the unit, either via armored or shielded cable and available in 10 and 20' lengths. Installation is much simpler, reducing labor and material cost versus traditional copper piping installations and no need for valve manifolds.
The 629C family has a robust NEMA 4X (IP66) construction, which is also available with an integral LCD for localized data monitoring.
