CAS DataLoggers has supplied Accsense A1-01a wireless environmental data loggers, B1-06 wireless data logger gateways, and Dwyer E1-36 pressure transducers to a hospital for monitoring differential pressure and temperature in its cleanroom.
Hospital Cleanroom
Entry and exit for the cleanroom are through airlocks. HEPA filters are used to keep the environment free from particulate matter. The ambient temperature in the cleanroom and two differential pressure points that are situated outside and inside the room have to be monitored. Failures have to be detected immediately for preserving the integrity of the room.
For monitoring the ambient pressure and temperature, three Accsense A1-01a wireless environmental data loggers were used. The B1-06 has a built-in 10/100BaseT Ethernet, which allowed a linkage between the data and the Internet. The E1-36 pressure transducers enabled the monitoring of differential pressure both outside and inside the cleanroom. The wireless devices were easy to install. The Accsense sensor pods had 0-5 V and 4-20 mA inputs, and vibration, light, humidity and internal temperature sensors. They featured digital inputs, external analog sensors and a +5V DC output to provide power for external sensors. The pods acted as repeaters and the pod and gateway had a range of 250' and 90' indoors.
The data can be monitored wirelessly in real-time, and stored in cloud-servers. It can be downloaded into many databases in .csv format. Alarms can be set up to trigger phone, pager or email warnings. The data can be seen as charts in ranges for as long as 90 days or as short as 5 min. These devices help prevent delay in staff response time to address equipment failure. The dataloggers helped the hospital to ensure its safety measures and cleanroom integrity.
