LCD-H20 loop-powered LCD display for mounting in INOR connection head

Description

The LCD-H20 loop-powered LCD head-mountable display is a digital indicator for mounting directly into a 4-20 mA loop without the need for an external power supply.

The LCD-H20 display features bright, easy-to-read LCD numbers that are easily programmable with three keys without a reference signal for values between -1999 to 9999.

As an option, the LCD-H20 can be purchased with a connection head. The instrument is designed to be mounted in the head with a glass window. For direct sensor input, the transducer can be integrated directly into the sensor housing.
