The NT-ELD Series Electronic Level & Temperature Switch with Display (Nivovent NT-ELD Series) is engineered and manufactured by Bühler Technologies GmbH – a premier German technology company globally recognized for advanced fluid control solutions and hydraulic reservoir automation. The NT-ELD series represents a next-generation smart monitoring solution that integrates continuous fluid level measurement and temperature sensing within a single microprocessor-controlled instrument.
In hydraulic power pack management and industrial lubrication systems, accurate tracking of oil level and operating temperature is vital for protecting pumps, valves, and downstream production lines. The Bühler NT-ELD resolves these operational demands through an intelligent microprocessor paired with a crisp digital LED display. The display head features a 320° rotatable mechanism, allowing engineers to comfortably read live parameters from any mounting angle. The display provides an intuitive programming interface to customize switching thresholds, hysteresis, and output signal formats without needing external programming devices.
Key technical highlights of the Bühler Technologies NT-ELD:
- Integrated Multi-Parameter Monitoring: Continuously measures fluid level percentage alongside real-time oil temperature (°C / °F), completely replacing traditional mechanical float switches and stem thermometers.
- Microprocessor Electronics & 320° Rotatable LED Display: 4-digit LED display clearly indicates measuring parameters, integrated with IP65 programming keys. The rotatable display head optimizes visibility in confined cabinet spaces.
- Versatile Output Signal Options: Offers configurable PNP/NPN solid-state switching outputs (2 or 4 alarm contacts), continuous analog outputs (4-20 mA / 0-10 V) for level and temperature, and supports modern IO-Link digital communication.
- Heavy-Duty Industrial Construction: Sensor stems and magnetic floats are crafted from 316L Stainless Steel (1.4571) or precision-machined Brass, providing high chemical resistance against hydraulic fluids and synthetic lubricants.
- Standardized Process Connection: Mounting flange complies with international standard DIN 24557 Part 2, enabling effortless retrofit or direct installation onto existing hydraulic oil reservoirs.
The Bühler NT-ELD electronic sensor is the primary choice for hydraulic power units in plastic injection molding machinery, CNC machine tools, steel rolling mills, cement plants, thermal power stations, metallurgical facilities, and automated lubrication systems.
