2-wire-Panel meter

Model 301/305:

Autopowered bright red LED- display 201 needs no external powersupply. Current signal 4-20mA provides

the necessary energy. therfore, it is possible to install themeter in places having no auxiliary power

available.

You can now replace the autopowerd LCD- displays, having verypoor visibility, by right red LED-displays.

Model 311:

The wide varenty of sensor types makes the panelmeter 211 idealfor all kind of temperature applications.

Further, the 211 also accepts thermopile infraded sensors andprocess inputs 4-20mA an 0-10V. Sensor

selections, display and output  scalings are easy to dowith front keys. You can also prevent access to the

menu by setting a password.
