THP-303-SSC & THP-303-SSW – (T + RH + DP) Indicator Transmitter – 0.5” display (3 x 4-20mA) retransmission output and/or RS485 interface.
Libratherm offers Mini Environment Monitoring System THP-303, micro-controller based Temperature, Humidity, Differential Pressure Indicator cum Transmitter with 0.5” high digital display for long-distance visibility and 4-20mA retransmission outputs for T, Rh, and DP each.
Digital interface such as RS-485 is integrated with the hardware to communicate with PC or PLC or HMI. Libratherm offers windows based PC software to monitor and store the data in a 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.
Respective sensors for T, RH, and DP are built-in to the same indicator, or alternately provision for external sensor/transmitter is available.
This Industrial Digital Temperature and Humidity Reader is housed in an elegant SS enclosure with a depth of just 40mm and hence can be easily concealed inside the PUF panels of the clean rooms. 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.
