Rotronic CRP5 Clean Room Panel for controlled environments
Overview
Rotronic’s CRP5 Clean Room Panel incorporates distinctive technology and design to enable easier measurement and management of ultra-clean controlled environments.
The CRP5 is the obvious choice wherever a high degree of cleanliness is vital. It is particularly useful in laboratory clean rooms, hospital operating theatres, in the pharmaceutical, electronics, and foodstuffs industries, and wherever small variances in pressure and environment conditions need to be constantly monitored.
Design and Features
The new Clean Room Panel is specifically designed for clean room applications and is fitted with a diaphragm differential pressure sensor and validated according to cGMP directives.
The CRP5 is distinguished from competitors by its removable HC2-CRP humidity and temperature sensor, which is magnetically attached to the easily cleaned toughened glass front plate.
Other features include:
- Measures differential pressure, humidity and temperature
- Designed specifically for clean rooms
- FDA- and GAMP-compatible
- Digital communication via Ethernet RJ45 and MODBUS TCP / RTU
- Analog input and output signals freely configurable
- Glass front panel highly resistant to chemicals
- Optical operating elements for operation with protective gloves
Benefits
The well thought-out design makes the CRP5 perfect for applications in laboratories and clean rooms. The unit’s comprehensive functional capabilities provide solutions for many measurement and control tasks.
It can simultaneously monitor numerous variables, including differential pressure, humidity, and temperature.
The removable sensor and single glass surface, together with optical buttons, permit easier and more efficient cleaning and operation.
The new panel’s graphical color display can display up to six measurement values and messages and allows display colors to be individually set and changed. The unit can be configured directly using the panel buttons or remotely via RS 485 or Ethernet interface with PC or via MODBUS.
The display highlights alarms for faults, exceeded limit values, warnings, etc. Alerts can also be forwarded digitally via MODBUS, Ethernet, or relays. A mix of analog and digital communication capabilities makes the CRP5 very easy to integrate in any monitoring system.
