Differential pressure module for Si-C320 transmitters. For installation in transmitters already delivered. Connector for external type K thermocouple probe (probe not included, please check our available models).

The Si-PRO-DP modules for Si-C320 transmitters have a temperature compensation from -10 to 50°C (14 to 122°F) and an auto-calibration process that ensures an excellent stability and a perfect reliability of the measurement in both low as high range over time.

  
Main applications: differential pressure monitoring in clean rooms, pharma/cosmetic and semiconductors manufacturing facilities, hospital isolation rooms, operating rooms and other critical environments.
