Clean Room Monitor and Real Time Data Logger – THP-3003

Libratherm offers model THP-300X, micro-controller based (T + Rh + DP) Indicator cum Transmitter with a 1” high digital display for long-distance visibility and 4-20mA retransmission outputs for T, Rh and DP each. Real-time clock and calendar are visible on demand through keyboard selection.These instruments are specially designed for monitoring and real-time data logging of cleanroom environmental conditions. Models are also available without a data logging facility, i.e. without a real-time clock and built-in memory.

Digital interfaces such as RS-485 or Ethernet are integrated into the hardware to communicate with PC, PLC or HMI. All three indicators have built-in memory and real-time clocks to store the T+RH+DP values at regular and programmable time intervals. The stored data can be downloaded
onto the computer via RS-485 or LAN connection. Libratherm offers Windows-based PC software to monitor and store the data in continuous or batch format for online or offline viewing and analysis in tabular or graphical format. The software allows users to prepare the batch report with
desired fields such as product name, batch name, customer name, etc. The THP series has built-in flash memory to store real-time 20000 + records.

The respective sensors for T, RH, and DP are built into the same indicator, or alternatively, the user can provide an external compatible sensor/transmitter.

The indicator is housed in an elegant SS enclosure with a depth of just 30mm, which makes it easy to conceal inside the clean rooms’ PUF panels. The front facia has slanted borders to prevent dust accumulation. All input and output cable connections are accessible from the top surface, and DP connections are available through suitable nozzles on the bottom.
