Product Analysis: Kobold NMT-12-0X-X50 Transmitter
The Kobold NMT-12-0X-X50 is a high-performance multi-functional sensor designed for the simultaneous measurement of liquid level and temperature in industrial tanks. By integrating both measurements into a single probe, the NMT series reduces hardware costs, minimizes tank penetrations, and simplifies electrical wiring. It is the preferred solution for monitoring hydraulic oil reservoirs, coolant tanks, and chemical storage vessels where both fluid level and thermal stability are critical.
Dual-Sensing Technology and 4-20mA Output
The NMT-12-0X-X50 utilizes a high-resolution reed contact chain for level detection and an integrated Pt100/Pt1000 element for temperature sensing. This specific configuration provides dual 4-20 mA analog outputs, allowing for continuous real-time monitoring of both parameters via a PLC or digital readout. The «12» in the part number refers to the 12mm guide tube diameter, while «X50» indicates a specific measuring length or resolution variant optimized for mid-sized industrial reservoirs.

Performance and Durability
The NMT-12-0X-X50 is engineered for long-term operational stability. The stainless steel 316L construction ensures excellent chemical compatibility and resistance to corrosion. The analog signals are highly resistant to EMI, allowing for long cable runs between the tank and the control cabinet. Because the level measurement is based on a float moving along a sealed guide tube, the sensor is not affected by changes in the medium’s pressure or the presence of surface foam, providing a more reliable reading than ultrasonic alternatives in confined spaces.

Technical Note
When installing the NMT-12-0X-X50, ensure there is sufficient clearance for the float to travel the entire length of the probe. In media with high particulate content, periodic cleaning of the guide tube is recommended to prevent float jamming. The dual output is easily scaled within most industrial controllers to provide precise volumetric or thermal data.
