Temperature Transmitter

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.

Features

• Two wire design (supply and output on the same lines).
• Accepts RTD (Pt-100) / thermocouple / millivolt input.
• (4-20) mA non-isolated and isolated output from the sensor.
• ZERO and SPAN adjustments for on-site calibration.
• Easily fits in std. thermocouple head (weather or flame proof or in explosion proof JB).
• Loop supply of 12 to 36VDC (with loop continuity LED)
• Saturation or open sensor current limited to 25mA.
• Reverse polarity protection.
• Available in both head mount and DIN rail mount.

Applications

• Carry thermocouple or RTD signals over long distance without noise and loss of accuracy.
• Eliminates use of costly compensating cable.
• Useful for converting other mV/Ohms signal to equivalent 4-20mA loop
