Temperature measuring transducer RT 420 for head and rail case mounting
- Greisinger electronic
Temperature measuring transducer 4-20mA,
Pt100, 2-/3,- or 4 wire
for head and rail case mounting
Advantages:
Low-price and robust (completely sealed - not pots,
therefore vibration resistant and long time stable) Freely programmable> 25°C) Selectable probe connection as 2-/3- or 4-Leiter
programmable High accuracy (0,1%) Large ambient temperature range (-40
to +85°C) error message in case of sensor damage
or sensor short-circuit functional warranty 5 years
