level transducer

Product catalog summary

Specifications:
The digital level transducer models NI 1331 and NI 1332 offer a linear measuring range from 150 to 4000 mm and are suitable for fluids with densities between 500 and 1500 kg/m3. They feature wear-resistant, inductive measurement, a slim design, and a rotatable LED display. The output signal is 4...20 mA.

Optional Features:
Options include a 7-segment display, CANopen interface, and reference vessels with various specifications.

Technical Data:
The transducers operate within a temperature range of -60°C to +280°C for NI 1331 and -20°C to +70°C for NI 1332. They support a maximum pressure of 100 bar at 20°C for PN100. The devices are powered by a 24 V DC supply and have a protection rating of IP 65.

Operation:
The level is determined by the buoyancy of a displacer in the fluid, with the output signal being 4...20 mA. Calibration requires knowledge of the medium and its temperature. For dynamic fluids, a protective tube is recommended.

Applications:
The transducers can be used for level measurement with LED display, pump regulation, and continuous level control with electronic controllers.

Installation and Calibration:
The transducers must be mounted vertically for optimal performance. Calibration is factory-set based on order specifications, and the chain length should not be altered post-calibration.

Electrical Connection:
Shielded cables are recommended for error-free operation, with connections detailed in the accompanying figure.

Mounting Position:
The device should be mounted vertically, and insulating the reference vessel is advised to reduce thermal radiation effects.

Dimensions:
The standard chain lengths are 96 mm for PN 40 and 192 mm for PN 63,100, with corresponding numbers of chain segments.
