Two Wire Temperature Transmitters - China

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 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 require 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 flame proof / 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 center 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 Galavanically 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.
