Standard equipment —
CRYO LC®

CRYO LC® consists of the basic module as a built-in unit for C-rail with a level probe manufactured to customer specifications and the display and control unit (optional components) and housing.

The CRYO LC® can be used in containers and systems of all sizes where the level probe can be installed.

  • Pressure-independent operation
  • Switch-on protection against manipulation and incorrect operation
  • PLC-compatible interface
Productinformation

Reliable control and
regulation of filling levels.

Functions

Level detection: detection of 4 levels (LEVEL 1 to LEVEL 4), display and signal output (= potential-free changeover contacts).
Level control: automatic control of the level between LEVEL 2 and LEVEL 3.
In both functions, an alarm is triggered if the level falls below LEVEL 1, exceeds LEVEL 4 or sensor short-circuit or sensor wire breakage.

Application

The device can be installed in different ways:

  • Compact unit, wired ready for operation, in housing with display and operating unit
  • Switch cabinet installation, modular, CRYO LC® basic unit for mounting on C-rail, display and operating unit with ribbon cable ready for installation in the switch cabinet door
  • Switch cabinet installation, modular, CRYO LC® basic unit for mounting on C-rail, without display and operating unit, control and signal polling can be done directly by a PLC
  • two display and control units on one CRYO LC® basic unit (local and remote)

 

Application examples:

  • Phase Separators
  • Dewars/Cryostats
  • Cooling baths

Level detection:

The filling level is detected by four sensors.
A fifth PT sensor is located at the lowest point of the level probe as a reference sensor. Only when this reference sensor falls below a temperature of approx. -100 °C is the level detection activated. The states LEVEL 1 to LEVEL 4 are displayed on the display and control unit and can be accessed on the basic unit via the potential-free changeover contacts. If LEVEL 4 is exceeded or LEVEL 1 is not reached, an alarm is triggered (visually and acoustically on the display and control unit or via potential-free changeover contacts on the basic unit).

Level control:

The level is automatically controlled between LEVEL 2 and 3. If the level falls below LEVEL 2, a potential-free change-over contact on the basic unit switches, via which a solenoid valve can be controlled. When the level reaches LEVEL 3, the changeover contact switches again and the solenoid valve closes. The filling process is indicated on the display and control unit via "FILL". The function can be switched on and off on the display and control unit using the "AUTO FILL ON" and "AUTO FILL OFF" keys.

 

Convincing advantages:

  • Modular structure
  • fast assembly
  • Simplest operation
  • Individually adapted level control and level probe, depending on application and customer requirements
  • For installation in a control cabinet or as a separate, stand-alone unit
  • Measurement and control independent of pressure, as measurement is made against a reference sensor
  • The basic unit can be operated simultaneously with at least two display and control units (local and remote control)
  • Switch-on protection against manipulation and faulty operation/device only goes into automatic mode when the reference sensor is colder than approx. -100 °C
  • level measurement self-monitoring, as the sensors are monitored for wire break and short circuit
  • Each signal (LEVEL 1-4, Fill, Alarm) is doubled as a changeover contact
  • Potential-free changeover contacts: with high switching capacity (230 VAC/3 A), therefore external devices can also be directly controlled via them
  • SPS-compatible interface
  • flexible power supply in wide ranges (85-264 VAC and 24 V DC)
