CellaTemp® PZ 21 -PROFIBUS DP-

PZ LWLPZ AnschlussseiteCellaTempPZ Profibus
The sensor head of the CellaTemp® PZ 21 is housed separately from the electronics assembly. Both the sensor head and the fibre optic cable are unsusceptible to electromagnetic radiation. The optical sensor head can withstand ambient temperatures up to 250 °C without cooling. This variant is ideal for cramped, hard-to-access locations.

Caution: The fibre optic cable must be ordered separately (see "Optical Accessories")!
