LCD-H20
Loop Powered LCD Indicator for In-head Mounting
LCD-H20 is a digital indicator for installation directly in a 4-20 mA loop
without need for external power. LCD-H20 is designed for in-head mounting in a sensor connection head with glass window.
The indicator is equipped with high-contrast, easy-to-read LCD digits.
The scale is easily programmable, without reference signal, by three pushbuttons for any values between -1999 and 9999.
As an option, LCD-H20 can be delivered mounted in a connection head.
