High precision measurement instrument for monitoring of differential pressures, available in 2 versions as pascalswitch 20 and pascalswitch 100.
Outstanding accuracy, reproducibility and long-term stability
Two threshold values including delay function and hysteresis are freely programmable throughout the whole measurement range
Two integrated relays and led`s indicate when the threshold values are crossed
The sensor is easy to calibrate by the end user
The device parameters can be set easily by using the pascaltool-palm configuration software or a palm pc emulator
Option:special version pascalswitchc 20 and pascalswitchc 100 with rs232-connecting interface for an easy integration in a process visualisation or control system. A dll [dynamic link library] as software development kit is also available.
