631B-0 631B-1/2/3/4/5 液用差壓變送器 Dwyer德威爾-上海茂培供應

631B系列 液用差壓變送器能精確地監測空氣，兼容的液體或氣體的差壓。輸出標準的兩線制回路的4-20mA信號。前面板帶數字按鍵，能夠容易校準零點和量程。631系列變送器的防護***別為NEMA 4X （IP66），結構牢固，耐壓500psi，并能測量差壓到0.5英寸水柱。

The Dwyer SERIES 631B Capsuhelic? Differential Pressure Transmitter monitors

differential pressure of air and compatible gases and liquids with accuracy. The design

employs converting pressure changes into a standard 4-20 mA output signal for two

wire circuits. Digital push-button, zero and span adjustments are easily accessed on

the front cover. The Series 631 Differential Pressure Transmitter is designed to meet

NEMA 4X (IP66) construction. Robust housing offers 500 psi static pressure rating on

ranges down to 0.5 in w.c.
