“SIStec SL3 ABB LM80 LASER Level Transmitter 30M Range 4-20mA With P801 Dust Tube” is a laser level transmitter produced by ABB company, the following is its relevant introduction:
How it works: The SIStec SL3 ABB LM80 LASER is based on pulsed laser technology, in which the transmitter fires laser pulses at the target surface, the laser encounters the surface, reflects back, and is detected by a sensitive optical receiver inside the instrument. By measuring the time of light transmission between the instrument and the target surface, using the time of flight calculation, combined with the known container height, the level can be accurately measured,

Performance characteristics:
Measuring range: SIStec SL3 ABB LM80 LASER for level applications, measuring range up to 100 meters; When used for positioning applications, the range can reach 150 meters, but the title specifies that the measurement range of this model is 30 meters, which may be limited according to the specific application scenario.
High accuracy: The SIStec SL3 ABB LM80 LASER features high precision timing and complex signal processing for precise measurement.
Non-contact measurement: It is a maintenance-free, non-contact continuous level sensor, which can avoid wear, corrosion and other problems caused by direct contact with the measured substance. It is suitable for granular solid materials and opaque liquids, and can measure solid and opaque liquids at any Angle.
Strong anti-interference ability: it has a narrow beam divergence Angle, almost no false echoes, and is not interfered by sediment, structure or blanking on the side of the silo. It can also penetrate light and moderate dust, and can work normally in a dusty environment.

Output signal: The SIStec SL3 ABB LM80 LASER provides continuous 4-20mA current output for easy connection with other industrial control devices, as well as a single point relay output for high and low alarm functions.
Other features: Built-in laser pointer for accurate alignment of narrow or tall containers; With automatic range function, can measure the property level; CSA, ATEX and IECEx explosion-proof certification for use in potentially explosive environments.
Supporting parts: Equipped with P801 dust-proof tube, can prevent dust and other impurities into the transmitter, affect the measurement accuracy or damage the internal components, help to maintain good working condition in dusty industrial environment.
Application scenario: Widely used in mining, petroleum, chemical, grain and other industries, can be used to measure the level of granular solid materials or opaque liquid in various storage tanks, silos, silos and other containers, such as gold and metal ore, coal, corn, plastic particles, oil and fuel storage container level measurement.
