可以。变送器可安装在竖管中用来过滤掉湍流和表面泡沫。管径可选择从 1" 至 6" 。
可以在竖管应用中使用变送器吗？
什么是继电器输出?
A Relay output is a small mechanical dry contact switch. The sensors internal circuit tells the relay to energize or de-energize when a change to the input has occurred. The relay can be wired either normally open or normally closed by reversing the polarity of the circuit.
What is the difference between the Relay and the FET?
The Relay is a mechanical switch. A tiny arm moves inside the relay providing either an open or closed contact. A FET switch (Field Effect Transistor) is a solid state switch, no moving parts. The FET switch is designed for interfacing to a PLC. The maximum rating for the FET is 36 VDC @ 100mA. The Relay is designed for interfacing directly to a device such as a light buzzer or another relay. The maximum rating for the Relay is 60 VDC/VAC @ 1A.
三线和两线UCL-200超声波传感器的区别是什么?
三线制 UCL-200系列的量程 (24.5" & 40") 比二线制的量程(18")更宽.
What size cable should I use to wire a two wire level transmitter back to a relay controller?
Generally, 18-gauge cable should be sufficient for distances of up to 1000 feet. Shielded cable is recommended, especially in areas with high amounts of electrical noise. The entire loop resistance should not exceed 900 ohms.
