Temperature sensor for solar or battery
power
The Moore Industries LRX low-power temperature transmitter has an exceptionally low power consumption of only 3mA, perfect for sites where line power is not available.
The Moore Industries LRX low-power temperature transmitter is designed for oil and gas well-heads and similar installations where line power is not available With an exceptionally low power consumption of only 3mA, the LRX mounts in remote or infrequently accessed field locations where solar or battery power systems are used

Measuring boiler and furnace temperatures simply
Protection tubes and flexible sensors make it possible to replace thermocouples in boilers and furnaces, without shutting down the entire process for days or weeks
The LRX accepts a three-wire 100 Ohm platinum RTD, K-type thermocouple, or direct millivolt input.
It converts the input to a 1-5Vdc signal for direct interface with readout instruments, recorders, DCS, PLCs and computer-based SCADA systems.
It will operate accurately in a wide range of ambient temperature conditions from -45C to +82C (-50F to +180F), and in humidity of 0-95%, non-condensing.
Accuracy is +/-0.15% of span, including the combined effects of linearity, hysteresis and repeatability.
Zero and span are set from front panel potentiometers.
Electrical protection includes transient protection on the output to 24V, reverse polarity protection on the output, and standard RFI/EMI immunity of 10V/m at 80-1000MHz when tested to IEC61326.
An RF option provides RFI/EMI immunity of 20V/m at 80-1000MHz.
For installation in harsh environments, the LRX can be ordered in a tough explosion-proof NEMA 4X (IP66) enclosure.
