Control system
CryoModul
Control system für Liquid Nitrogen
Application
CryoModul is a universally applicable control system for the fully automatic control and monitoring of liquid nitrogen in tanks and transfer lines. CryoModul controls pressure and level in tanks and phase separators. Additionally, CryoModul controls central gas bypass systems, filling levels (CryoFill) and tank switching systems (CryoSwitch).
Structure
Description
CryoModul consists of a stainless steel housing with LED operating buttons, an integrated power supply and individually programmable control unit. The control buttons and the LCD text display can be viewed and operated through a transparent hinged window. Solenoid valves, level sensors, pressure sensors and temperature sensors are connected via cable glands on the underside of the housing.
Features
- Level monitoring with a 4-point sensor system, alternatively with capacitive level or pressure differential measurement
- Pressure monitoring via pressure transducer
- Control of filling, exhaust gas and changeover valves
- Control of gas bypass system or filling system via temperature sensor
- Collective fault signal, potential-free, NC contact
- Setup directly on the control unit
- Communication: Ethernet TCP/IP, Modbus TCP, web interface
