631B-0 631B-1/2/3/4/5 液用差压变送器 Dwyer德威尔-上海茂培供应

631B系列 液用差压变送器能精确地监测空气,兼容的液体或气体的差压。输出标准的两线制回路的4-20mA信号。前面板带数字按键,能够容易校准零点和量程。631系列变送器的防护级别为NEMA 4X (IP66),结构牢固,耐压500psi,并能测量差压到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.
