THP-3001-SSC(Only DP or T or RH) Indicator Transmitter - 1" display with built in real time data storage
THP-3002-SSC(T + RH) or (T + DP) or (RH + DP) Indicator Transmitter - 1" display with built in real time data storage
THP-3003-SSC(T + RH + DP) Indicator Transmitter - 1" display with built in real time data storage

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

Digital interface such as RS-485 or Ethernet are integrated in the hardware to communicate with PC or PLC or HMI. All three types of indicators have built in memory and real time clock to store the T+RH+DP values at regular and programmable time interval. The stored data can be downloaded onto the computer via RS485 or LAN connection. Libratherm offers Window based PC software to monitor and store the data in continuous or batch format for on line or off line viewing and analysis in tabular or graphical format. The software allows user 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.

Respective sensors for T, RH and DP are built-in to the same indicator or alternately provision for external sensor/transmitter is available.

The indicator is housed in an elegant SS enclosure with the depth of just 30mm 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 top surface and DP connections are available through suitable nozzles on the bottom (As shown in the photographs).

Features:
  • Microcontroller based design.
  • Elegant appearance, easy to operate and compact in size.
  • Highly accurate and sturdy in operation.
  • Three colour 1” display for simultaneous indication of T, Rh and DP.
  • Ready for both analog and digital data transmission.
  • Built in memory and RTC for real time data storage.
  • Stainless Steel (SS) enclosure.

FTX-3000-THTemperature + Relative Humidity Indicator Transmitter - with dual 4-20mA retransmission output and RS-485 interface in FLP enclosure


Description:
Libratherm offers micro-controller based only Temperature, only Relative Humidity and both T + RH Transmitter models as specified above in flame proof field mount enclosure, for measuring and indicating Temperature and Relative Humidity in the field or in the process. The measured values are converted to the equivalent analogue and digital values proportional to the Process Input for long distance transmission and to interface to the PLC or DCS or any other field device. FTX-3000 is a very useful device to capture the low level signal from the hazardous area and bringing back the signal to the main control room.

Temperature and Relative Humidity values corresponding to the input is indicated on the digital display and the corresponding display range is converted to the 2 wire current or voltage output of 4-20mA/0-10VDC proportional and linearized to the selected process input. This linearized signal can be used for remote measurement and indication. For the dual input models, two independent 4-20mA/0-10V signals are available. The analog outputs are isolated from the DC power supply.
To interface low level field signals with PLC or DCS or with any other process controller – the measured and displayed analog values are converted for digital serial communication on isolated RS485 bus with MODBUS RTU protocol in slave mode.

Advantage of RS485 interface: Providing the feature of RS 485 digital serial interface is advantageous, since the number of wires coming from the various sensors / transmitters can be avoided and instead, only two wires can be used to interface multiple such FTX-3000 on serial port. The digital communication has the greatest advantage of exactly replicating the process value, that is what is measured at the plant and what is displayed in the control room always matches one to one as compared to transmitting the analogue values. In today’s technology, most of the PLCs and DCS accepts RS485 digital interface.

Features:
  • Microcontroller based design.
  • Single or Dual Temperature / RH input .
  • Isolated single or dual 4-20mA output, proportional and linearized to the selected input.
  • RS-485 MODBUS RTU serial interface.
  • Bright red LED display.
  • IP 65 Flameproof Enclosure – suitable for Gas group I, IIA and IIB.
