BESTACE微差压变送器761系列产品介绍

Model 761 series are low range differential pressure transducers and transmitters. It features a flame retardant plastic enclosure with a metal backing. The unique design makes it can be used at outdoor environment and with easy access to zero and sensitivity adjustments.

The pressure range covers from 0.1"WC to 100"WC， unidirectional or bidirectional. The output can be 3- -wire 0 to 5V, 0 to 10V, or 2-wire 4 to 20 mA, fully protected against short circuit and incorrect wiring. In the voltage version, the output can go down to true zero. The units are temperature compensated. The accuracy can be 1.0%, 0.4% or 0.25% at room temperature.

The patented stainless steel sensor provides good corrosion resistance, excellent performance and long term stability.

Our unique production setup can also make special pressure range (e.g. -0.5"WC to +3.5" WC) to meet special applications.

761系列是低量程差压变送器和变送器。它具有带金属背衬的阻燃塑料外壳。独特的设计使其可以在室外环境中使用，并且易于进行调零和灵敏度调整。

压力范围从0.1“ WC到100” WC，单向或双向。输出可以是3线制0到5V，0到10V或2线制4到20 mA，完全可以防止短路和错误接线。在电压版本中，输出可以下降到真正的零。单位是温度补偿的。在室温下，精度可以是1.0％，0.4％或0.25％。

获得专利的不锈钢传感器具有良好的耐腐蚀性，出色的性能和长期稳定性。

独特的生产设置还可设定特殊的压力范围（例如-0.5“ WC到+3.5” WC），以满足特殊应用。
