Product catalog summary
General Characteristics
The continuous level sensor is constructed from stainless steel (AISI 316) and offers measuring resolutions of 5, 10, or 20 mm. It provides various signal outputs including potentiometric, 4-20mA, 0-5V/0-10V, and 4-20mA with digital display. The sensor can measure up to 6 meters in length and withstands a maximum working pressure of 50 Bar. It operates in ambient temperatures ranging from -30°C to +55°C, with a standard working temperature up to 105°C, extendable to 150°C upon request. The device has a minimum protection degree of IP65 and can include built-in temperature sensors (PT, PTC, NTC) upon request. ATEX constructions are available for hazardous environments.
Floats
Various float types are available, each with specific dimensions, materials, and maximum operating conditions. The floats are made from stainless steel (AISI 316) with specific gravities ranging from 0.55 to 0.75. They support different measuring resolutions and maximum pressure and temperature ratings.
Electrical Output
The sensor offers multiple electrical output configurations, including IP65 and IP68 housings with various plug and cable-gland options. The potentiometric principle of operation ensures high reliability, with the only moving part being the magnetic float.
Process Connections
Installation options vary based on the sensor type, with both internal and external installation methods available. The process connections support various thread types and materials, including AISI-316 and steel, with flange options conforming to UNI, DIN, and ANSI standards.
Wiring and Dimensions
The sensor supports potentiometric, 4-20mA, and 0-5/0-10V outputs, with optional digital display. Dimensions are specified with tolerances, and optional built-in temperature sensors can be installed. The nomenclature section provides a detailed breakdown of the sensor's configuration options, including type, float, measuring resolution, length, material, and electrical output.

LINEAR S-1

Continuous level sensor GENERAL CHARACTERISTICS The principle of operation is of potentiometric type, based on the gradual shutdown of a chain of resistors and reed contacts, placed inside the guiding rod, by a magnetic float. The only moving element is the float that moves, for buoyancy, along the measuring rod. This ensures a high degree of reliability. • Stainless steel ─ AISI 316 Measuring resolution 5 – 10 – 20 mm. Potentiometric signal output (LC). 4-20mA analog output (LCT). 0-5 / 0-10V analog output (LCTV). (0)4-20mA analog output with digital display (LCO). Up to 6m length. Maximum working pressure 50 Bar Operating ambient temperature -30/+55°C UR 90%. Standard working temperature up to 105°C. Executions up to 150°C on request. Minimum degree of protection IP65.
