Lake Shore Cryotronics makes benchtop instruments for precision cryogenic temperature measurement. Now the same measurement performance can be achieved in distributed Profibus applications using the company’s new 240 Series sensor input modules, currently available on a pre-sale basis.
Designed for particle accelerators, fusion reactors and any physics or industrial application employing distributed PLC-based control, the modules offer a solution for precision monitoring of cryogenic sensors, including Lake Shore Cernox RTDs, platinum RTDs and silicon diodes.
The DIN rail-mountable modules can be networked to PLCs for temperature monitoring in large-scale facilities. Temperature values are communicated directly to the PLC master device, eliminating the need to use additional, costly analog conversion equipment or complex PLC programming to generate temperature values. Building on Lake Shore benchtop instruments, the manufacturer says the modified measurement circuitry allows for longer cable runs between a sensor and the module. This is useful for applications where sensors must be located in hazardous environments.
The modules are available in two versions, allowing users to balance between the high-speed 2-input module or the high-density, cost-efficient 8-input version.
