CSmicro 2W LTxxH as analog device (mA two-wire-output) – current measurement in GND- (Loop-) 
line 
 
 
 
On the models LT15H and LT22H (sensing heads for ambient temperatures up to 180 °C) and on the special 
versions for 250 °C ambient temperature the GND and Shield is connected inside the electronics. 
 
Special note for current measurement in GND- (Loop-) line: 
In this case the sensing head must be installed isolated from ground. A connection of the GND or Shield wire 
to earth is also not allowed. 
 
For a current measurement in the Power- (Loop+) line the drawing CSmicro 2W as analog device is valid. 
The Shield should be connected to ground or GND.
