Process monitoring device PUC 24

Cleanroom panel for displaying air-conditioning data


The PUC 24 process monitoring system is especially suitable for pressure monitoring applications in cleanrooms, laboratories, pharmaceutical plants and operating theatres. The system has two electrical inputs for humidity, temperature or external pressure transducers. The measurement values provided by these devices are displayed on the graphic LCD display. As well as recording differential pressure, it also measures positive and negative overpressure. Two optional contact points allow the user to connect visual or audible alarms that are triggered any time values rise above or fall below specified limits. A selectable time constant allows the transmitter to be adjusted perfectly to the pressure conditions. The PUC 24 is suitable for wall mounting in cleanrooms due to its smooth, solvent-resistant stainless steel housing. The device is easily integrated into central building control systems via the optional PROFIBUS DP interface.
