Temperature Transmitters

Libratherm offers Miniature Head Mount Two-Wire Temperature Transmitter Model LTX-3000-H, which accepts (Pt-100) or thermocouple or variable resistance signal as the input and provides dc current output of (4-20) mA proportional to mV or resistance values. These transmitters are extensively used to minimize the effect of electrical noise and to eliminate the need of long runs of special compensating and three wire cables since an ordinary pair of copper wires can easily be used to transmit the measured temperature without the drop or loss of signal. In addition, transmitting the current signal is more advantageous, since it is less susceptible to industrial RFI/EMI noise compared to the voltage signal. These transmitters are linearly calibrated to the signal produced by a thermocouple or RTD sensors and not to the actual temperature.
LTX-3000 requires no separate power supply as it is powered by current drawn from the current loop itself and is thus intrinsically safe when used with appropriate barriers. It is very compact, economically priced and can be directly mounted inside standard heads of the thermocouple or RTD sensors. It can also be easily fitted inside the flameproof/weatherproof head or junction box. It is available for different thermocouples, RTD (Pt-100) duly calibrated for required temperature range with ZERO and SPAN adjustments for on-site calibration. LTX-3000 is available in the standard size of 44mm OD and 26mm height (with the terminals) and centre to centre mounting hole dimension of 33.0 mm so that it fits easily into the standard head.

The Transmitter is also available in DIN Rail compatible modules Model LTX-3000-D, in weatherproof enclosure Model LTX-3000-W, and in flameproof Model LTX-3000-FLP.

The Galvanically isolated versions are also available in DIN rail and weatherproof enclosure as the Model LTX-3000-DI and LTX-3000-WI respectively, where input and output are isolated.

Isolated versions are useful and recommended for the applications, where the transmitters are mounted away from the sensors. The isolation prevents further the RFI/EMI and ground line interference on the 4-20mA signal loop.

New Model LTX-3000-H-2 is available for duplex sensors and can be fitted in the standard Head.

Libratherm offers micro-controller based FLP Enclosure Process Indicator And Transmitter model FTX-3000 in flameproof field mount enclosure, for measuring and indicating process parameters such as temperature, pressure, humidity, level etc..and converting to the equivalent analogue and digital values proportional to the Process Input for long distance transmission and 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 or Process values corresponding to the input is indicated on the digital display and the corresponding display range is converted to the 2 wire current 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 model FTX-3000-U-2 or FTX-3000-F-2, two independent 4-20mA/0-10V signals are available. The analogue outputs are isolated from the DC power supply. Single FTX-3000 can be used to capture two process inputs, thereby saves on size and price.

To interface low-level field signals with PLC or DCS or with any other process controller – the measured and displayed analogue values are converted for digital serial communication on the isolated RS485 bus with MODBUS RTU protocol in slave mode.

The advantage of the 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 a 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.
Universal single or dual industrial process input (user selectable).
RS-485 MODBUS RTU serial interface.
Bright red LED display.
