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
