8250 液位变送器

　　 Signet 8250液位变送器是和2250液位传感器和2450压力变送器兼容的。这种仪表有现场型和盘装型结构。仪表可有单路和双路输入，对每路输入都配备了可刻度和倒向的4-20mA输出。每块表配置了两个继电器，加上它能够提供的两个附加在外部的继电器（总共为4个继电器）。继电器工作可选高、低，触发、关闭，并包括全部继电器的延时和启动时间调节。仪表还可以接收通过8058转换的，其它输出4-20mA的传感器。自动的液位-容积的转换，允许对罐容积和液位的显示和控制。它们的单位可用加仑（gallons），千克（kilograms），英尺（feet）或米（meters），简单地输入你的罐或容器的尺寸，仪表将根据测量的液位计算出相应的值。

英文简介

8250 ProcessPro® Level Transmitter

Signet 8250 Level Transmitters are compatible with the Signet 2250 Level Sensor and 2450 Pressure Sensor. The instrument is available in field and panel mount configurations, single or dual-channel input and equipped with one 4 to 20 mA output, fully scaleable and reversible for each input channel. The unit also features two relays, plus the ability to support two additional externally mounted relays (for a total of four). Relay operations is selectable for High, Low, Window or Off, and includes fully adjustble hysteresis and trigger time delay.

The unit also has the ability to accept other level sensors with 4 to 20 mA output via the Signet 8058 Signal Converter. Automatic level-to-volume conversion allows display and control of tank level and/or volume in units such as gallons, kilograms, feet or meters. Simply enter the dimensions of your tank or vessel, and the instrument will calculate volume from the level measurement.

Fields of Application:

Continuous level and/or volume monitoring
Local or remote display
Fill start/stop control
Pump protection
Inventory Management
Storage Tank Monitoring
Pump Station Control
Plating Lines
Neutralisation Tanks
